Two Stroke Motocross.com: Questions Answered, Misconceptions Debunked.

By JohnNicholas • on November 20, 2009

During the past two years of this web sites existence, we have received a great deal of feedback, much has been extremely positive, with an out pouring of support. Thank you!

Not surprisingly some has been… well… not so good. Most of this negative feedback seems to come from those that don’t understand the nature, reason or the ideals this site is built upon. This article attempts to address those misunderstandings.

This is a web site devoted to the promotion of two-strokes in motocross racing. That’s kind of easy to understand when you read the name on the top of the page. But the doubters have quite a bit to say, some valid and worthy of a response. To date, we’ve answered each e-mail or comment individually, but have now decided to address the biggest misconceptions right here on the site.

While the chances are high that the doubters may never read this at all, I felt that it was important to share our philosophy and beliefs with you, our esteemed readers.

How do you like the new logo?

How do you like the new logo?

In the simplest terms, our goal is to promote and support two strokes in motocross in a truthful and respectful manner. We provide an opportunity for alternate manufacturers to reach a wider market, enabling them to supply machines, parts and support for those interested in the two stroke. Two Stroke Motocross also provides a platform to share news, information and technology about these light, simple and powerful engines.

So in no particular order here are some of the biggest myths about this site.

Stick_it_outFour-Strokes Suck!

The truth is that we don’t hate four-strokes. They can be great bikes. They allow beginners and vet racers to race without having to devote a great deal of riding  time in order to be competitive. When they’re not pushed to extremes and maintained properly, they can last a very long time.

Whenever we speak about the difference in cost between the 2 and 4 on this site, we are referring to what it costs for fast, competitive racers to compete. When you attempt to race in the A or Pro level, it is imperative to hop up the machine. Otherwise you will be left behind. The 250F machines are the ones that need big bucks devoted to the engines in order to be competitive. When the bikes are tuned to the high level required to be competitive, the chances of catastrophic problems increase.

Obviously all race machines require regular maintenance. This goes without saying. But when a catastrophic problem does occur, it will cost you significantly more with a four-stroke. If you think about it reasonably for just a few moments, it’s easy to understand the reason, there are many more moving parts. Also, if your machine is hopped-up, that adds an additional level of expense.

Quote from SuperMoto Junkie "rolling chassis,got it cheap from a dude that blew two engines in as many months,its an 07 crf450."

Quote from SuperMoto Junkie "rolling chassis,got it cheap from a dude that blew two engines in as many months,its an 07 crf450."

The stories of four-stroke owners unable to repair their bikes because the cost to repair them is more than the bike is worth are too numerous to ignore. In fact, there are folks that make money by buying these machines at a deep discount from the frustrated owners. These guys usually fix them and sell them or part them out. Sometimes they used to create new generation two-stroke bikes with the latest chassis design.

The issue to consider is what happens to the guy that gets burned on his “technologically advanced” four-stroke? Does he quit racing altogether? The chances are very high that he does. He leaves motocross, never to return. So instead of building up the base of new racers, the four-stroke “revolution” is having the exact opposite effect. Less people are getting involved with motocross.

"Ohh Man! I have to make payments for how long?"

"Ohh Man! I have to make payments for how long?"

This is simple to understand. Take into account that many riders have to finance the purchase of their new bikes. Could you imagine what it’s like to own a broken machine that’s sitting in your garage and you still have to make payments on it? That would be the ultimate slap in the face!

To add insult to injury, the used market for four-strokes is is getting worse as folks discover that it’s almost impossible to know how long a used four-stroke will last.

Usually a rider will buy a bike, race it for a year or two, then sell the machine, using the cash from the sale to off-set the cost of the next new one. But in this used bike market, he can barely sell it for enough to cover the down payment, so now he has to finance a greater and greater amount of money.

The question is, how many 5 year or older four-strokes do you see at the track? There are very, very few of them. But when you look at the two strokes, you see machines that can be 10 or more years old. The truth is that it’s inexpensive to rebuild the two-stroke. Plus the resale on used two-strokes can be higher than newer model four-strokes.

Need proof?

My local used bike dealer sells used two strokes all the time. In fact he has a hard time not selling them! When he advertises a two-stroke for sale, he gets a bunch of calls and e-mails for them.

They have tried a few times to sell used four-strokes. There were almost no calls on them, even when they were priced much lower than comparable or even older two-strokes. In fact they could go weeks or months with no interest on the used four-strokes. The only way they do sell, is if the dealer drops the price to almost nothing. It’s so lopsided, that they now refuse to sell any used four-strokes.

Displacement Disadvantage

Why is it that every time displacement is brought up, it strikes fear into the four-stroke lovers? In fact, no one has ever really answered this question in a meaningful manner. Lot’s of hot air and subterfuge, but no real explanations.

Still, the 4-stroke supporters shout from the roof tops that their machines are more technologically advanced than the two-strokes.

While they look similar, the bigger one is usually faster.

While they look similar, the bigger one is usually faster.

While it may be true that they have been updated more recently than some of the two-stroke offerings, what they all seem to leave out is that they are double the displacement.

How can something twice as big be a better machine or more advanced? It just doesn’t make sense.

In auto racing, the catch phrase for years has been “there’s no replacement for displacement.” Why is this so often quoted? Because in almost every single case, a bigger displacement engine will be faster. Yes, there are some exceptions to this “rule”, but for the most part it holds true.

Then there are some that attempt to explain that because the two-stroke fires on every stroke and the four-stroke fires on every other stroke, that the four-stroke needs to be twice the displacement. This has no basis in either mechanical or engineering fact.

Then there are others that say that displacement doesn’t mean anything. That machine size doesn’t matter because certain racers, on certain days can use a 125cc machine to beat a 450F’s.

Sure if your name is Ricky Carmichael, Chad Reed or James Stewart and you’re racing someone that’s not as good, they could beat them while using a mini-bike. When these guys compete against each other though, then displacement means a great deal. These guys have the ability to race almost any size machine to it’s limits. Unlike most mortal racers where displacement does make a big difference.

The four-stroke engine was invented by the German merchant and engineer Nikolaus August Otto in 1876. Photo of Gottleib Daimler who created the first motorcycle circa 1885.

The "technologically advanced" four-stroke engine was invented by German merchant and engineer Nikolaus August Otto in 1876. Photo of Gottleib Daimler who created the first motorcycle circa 1885.

What’s hard to understand is that for 72 years motocross was based on displacement, equal displacement. Until, in the early 1990′s, when a rule was set to allow the four-strokes a displacement advantage. Although it wasn’t until 1997 that Yamaha exploited the rule. Remember that the maiden championship series that the YZF400 four-stroke competed in, it won. Why wasn’t this rule abolished then and there?

No one really believed that the four-strokes were actually good enough to win all the time. Even with the almost double displacement advantage. This included most of the manufactures, the pro racers and the fans.

Because they had a huge displacement advantage people were drawn to them like bears to honey.  Then like any new technology, the four-strokes improved dramatically until the horsepower exceeded the smaller two-strokes. Who wouldn’t want to have twice the displacement with a mellower power delivery? By 2004, there were virtually no two-strokes competing in Pro Motocross. How can this be fair?

Two Stroke Motocross wants a level playing field – meaning equal displacement. If not equal displacement, let’s create a series that will allow two-strokes only or equal displacement racing.

Two Stroke Motocross is Biased Towards Two Strokes

Duhhh! Of course almost every article written on this site is about two-strokes, it is called Two Stroke Motocross. The reason that this site exists is that the mainstream media does not write very much about two-strokes. But the media receives most of it’s revenue from advertising. Guess who the largest advertisers are? Correct, the manufacturers of motorcycles. So what do they write about? The stuff that their advertisers sell and market. This is not a conspiracy, this is basic business.

Another example, is when the top stars of motocross are asked if they prefer two-strokes or four-strokes. Hmmm, let’s see, they’re being paid millions by a company to race the latest four-strokes that the company sells. What would you say? “No… I hate the piece of crap they make me ride, I rather race a two-stroke.” Hell no. If you were in their place you would say the same thing. It’s not a conspiracy, it’s the right thing to do.

Although as an interesting aside, it was fun to see James Stewart riding a two-stroke YZ250 during his ride days this year. While we’ll never know the reason that he did, it’s hard to imagine that Yamaha didn’t have another 450F for him to ride on these event days.

As for bias towards the two-stroke, we just tell it like it is. Every article we write is checked and researched to be sure that the information is true and factual. If we can’t confirm something is true or not, it will be noted that it is a rumor or that there is no conformation at the time the article was published. If the four-stroke is faster or is better in some way when compared to a two-stroke (of equal displacement) it will not be covered up or “edited” to make the two-stroke look better.

As an example, look at the Two Stroke Motocross article from a few weeks back. There was a video from Wildwood, New Jersey of a race between a 250 two-stroke and a bunch of 250 four-strokes. If you watch the video closely, you will notice that the two-stroke racer (Dakota Kessler) was going all out to beat the 250F’s. In no way was it a cake walk for him. He was successful because he was able to hang it all out and keep that old CR250 on the pipe. It was a terrific race and very exciting. It does show that equal displacement bikes can be raced head-to-head fairly. Well at least on that day and at that track.

Why Are There No Articles on SuperMoto? Quads? Freestyle? Road Racing? Etc.. On Two Stroke Motocross?

This is simple. While we love all forms of motorcycle racing and any instance where two-strokes are use in competition, our expertise is in motocross, so that’s the area we concentrate on. We are more than willing to publish articles about other forms of two-stroke competition. If you have news, information or stories that are meaningful or about new technology, please feel free to contact us and we’ll get it out there.

Too Freaking LOUD!

Sound issues. The loud and obnoxious sound of the four-stroke reminds regular folks (those that don’t like motorcycles) of Hell’s Angels. This is not an association that will help motocross to grow. In fact, it has done a great deal of damage to our sport. Riding areas and race tracks are being closed all over the world because of the noise. This issue must be dealt with in order for our sport to thrive.

Nostalgia

Seems that lot’s of detractors feel that only old guys want two-strokes. Supposedly, this is because two-strokes were the bikes “back in the day.” That might be true of some 30 somethings, but certainly not of everyone.

"I miss the good old days."

"I miss the good old days."

It’s not just the old guys that want two-strokes. The truth is many of the older guys prefer the four-stroke, because it’s easier to ride/race. In fact, if you are old enough (in your 40′s or older) you remember when motocross (scrambles at that time) consisted mostly of four-strokes. In which case, you’re probably more likely to buy a four-stroke.

Instead of guessing what others are interested in or what they are thinking, do what we do, ask the racers that you see at the track. In this way we made a discovery, the tide is turning. More and more racers are switching to two-strokes.

Some of the older guys are extremely interested in technology for motocross and are the first to adapt to new things. Although they realize when it actually is an advance and not just a marketing catch phrase. Most want whatever bike that best suits them, utilizing the newest technology available to them.

While all this debate between the two-stroke and four-stroke rages on, the truth is that in 10 or 20 years there may be something that is even better. As long as it is better and not a step backwards, it will be adopted by the masses.

News Flash! Some young people actually prefer two-strokes. Go figure.

Comments

"Go ahead... make my day."

"Go ahead... make my day."

Here is where we claim a home town advantage. When someone attempts to comment using lies, slander or saying stupid stuff, it gets deleted. This does not happen often and when it does an e-mail is sent to the “offending” writer, asking them to re-write it without the offending material.

You do not have to agree with everything written on this site, in fact if you know differently, we want to hear about it. This can be done in a respectful manner and should include facts. This site is not a free-for-all with no rules.

There are many sites that have forums that allow just about anything. They end up being “ruled” by bullies and know-it-alls. It appears that whenever someone could contribute to the spread of ideas, if these precious few disagree, they bully, call names and make fun of the new person until they just stop posting.

This site is a safe place to spread ideas, comment, disagree, or talk about the future. Just act like a mature adult. We have 15 year olds that understand this and act like adults. It can be done!

Conclusion

This site exists because people like you are interested enough to visit the site in your search for news and information about two-strokes. Why is this even possible? Because there is so little information all in one place about this subject.

Two Stroke Superhero? Well... not quite.

Two Stroke Superhero? Well... not quite.

We do our best to bring you worthy and timely information about two-strokes.

The truth is that no matter what is written on this site, if you disagree and your mind is made up, nothing written here will change your opinion. But that is not what this site is all about. No one can ever change your mind except you.

We’re here to learn about what is happening in the world of two-strokes, to examine ways to promote them and to encourage the riders that choose two-strokes. Two strokes are a viable alternative and there is support out there.

If you love two strokes, the way you can make a difference is to buy one. Whether they are new or used. From a major manufacturer or one of the smaller manufacturers. Buy the bike you feel is best for you. Go do it.

Thank you for reading!

Nice piece.

The issue will never be resolved for some people because they live in a world where if you don’t agree with them, they believe you’re telling them they are “wrong”.

The perfect dirt bike model world would offer choices in all displacements, either 2 or 4 stroke and the ability to race them at all levels.

Now if 2T-MX just had a discussion forum to go along with that fine new logo……………It would be to see what sort of traffic such a forum would generate. Traffic = sponsor interest = income= ability to grow…… ;)

By JohnNicholas on November 20th, 2009 at 2:41 pm

Hey Targo,

The thought has been there to set up a forum, but I had a few reservations. It opens you up to an enormous potential for fights, put downs and stupid stuff.

Can there be a forum that is respectful? I’d like to think so.

What do you the readers of this site think. Would you like to see a forum here dedicated to the two stroke aficionados?

Thanks!

By SCOOTER042 on November 20th, 2009 at 3:27 pm

Good write up.

Bring on the forum! Keep it small and simple and don’t ask questions, just delete anything that is in left field, It’s your forum, you make the rules. Zero tolerance for haters.

BRAAAP!

By Targo on November 20th, 2009 at 3:49 pm

I ran my own forum [equestrian] and it can be a lot of work to keep a lid on things. That said, I think a small forum without ANY “off topic” subject allowed [politics/etc.] would be great.

Start very small….one or two forum and if it needs to grow it can. Nothing looks sillier then a extensive site with many forums that aren’t used and there are quite a few of them out there.

Don’t take any BS from people either, if they don’t like how your run YOUR forum they can post elsewhere. Make the forum rules clear and enforce then fairly. People will still complain but that’s what some people do. Allow nothing to get personal between posters……focus on issues/ideas and not each other.

By billywizz on November 20th, 2009 at 4:04 pm

Here in the UK so many racers are turning to 2 strokes, they are sick of the cost of repairs & extreme depreciation on 4 strokes, this is right across the board including expert club riders. @ my local club (Whitby one of the premier tracks in the North of England) the 2009 expert club championship was won by a 2 stroke rider, oh! & 2nd & 3rd place were both on 2 bangers! this has not happened for years, also the pre 89 evo class bikes (nearly all of which are jap 2 strokes) are becoming more & more popular competing in dedicated championships across the country. Often riders are ditching a 4 stroke in favour of a bike which suffers no depreciation & just so much fun to ride – going back to the future!!!! keep up the good work.

Alright you asked for it!!

There is now a forum on Two Stroke Motocross. It is a work in progress, but it’s now up and running.

Buy a two-stroke, you say? Why don’t mind if I do. Next on my list of bikes-to-get is the ’78 Maico 440 Magnum. I’m really looking forward to getting my paws on a good ol’ big-bore Maico. I love my 250 Husky, but my dad’s 390 Husky needs someone to show it who’s boss! Although, I imagine that if I bought and rode a 440, he’d roll out his ’86 Maico 500 and I’d be back to square-one again. I wonder if I’ll ever catch up to the guy.

By motoman465 on November 21st, 2009 at 8:22 am

Very well written article just like all the others on this site, John. I have been saying for years that the four strokes have a place and a following. Just do not take away our choice if we want to buy and race modern 2 strokes. I am going to go get in on the forum right now, awesome idea. Thank you!

By Chris2T on November 21st, 2009 at 10:46 am

Hi John, just read your article and you put into words many of the feelings i have had over the last dozen or so years.
The one thing that I hear ALL the time that confounds me is this: a 250 4 stroke cannot compete on a regular basis with a 250 2 stroke, i think there is nearly universal agreement on that. Yet when you give the 4 stroke an 80% displacement advantage to 450cc, all of the sudden you hear people marveling over the “amazing power and tractability” of the 4 stroke over the 2stroke. Huh? Is this not the most illogical crap you ever heard? It can’t compete head-to-head, yet when given an advantage it is marveled over?? I mean it’s unbelievable!!

For nearly a century motorcycles competed against motorcycles of like displacement. When the rules were finally changed to give the 4 stroke an advantage why wasn’t more made of the triumph of the 2 stroke over the 4 stroke? I mean the 4 strokes finally capitulated!!! Instead all we heard was how amazing it was that a 4 stroke could even compete against the 2 stroke at all, and therefore they deserve all the accolades. Bottom line is that nothing was made of the fact that the 4 strokes threw up the white flag. Only legislation brought them back. Again, shameful. The 4 stroke fans are in denial.

I remember a few years ago when the CRF150R was being introduced and there were proposed new regs for the 85cc class, Roger Decoster was confounded that the regulations for each of the classes didn’t match. 125cc 2T v 250cc 4T = 100% displacement advantage. 250cc 2T v 450cc 4T = 80%. 85cc v 150cc 4 T = 75%. He said it perfectly – where is the parity?? Makes you wonder just who is the genius that is setting these rules!!

Don’t get me wrong, there are some things I dearly love about 4 strokes. I hugely admire their smokeless operation, how efficient they are with fuel, and some of their engine characteristics such as low end torque, how some of them look and sound, and how long lived they can be if not tuned to insanity. But there is just a pervasive unfairness out there that really turns me off to the whole 4 stroke thing.

Regarding direct-injection 2 strokes. I have been patiently waiting for years now to see a mass produced DI 2 stroke, and I can’t figure out what the delay is. On one hand, Aprilia has offered the 50cc Ditech scooter for over a decade so I thought maybe the direct-injection system only works on small engines. Yet Evinrude has produced 3.1 liter V6 outboard engines with DI for over a decade also so it can’t be a size thing. My guess is that the patent holders to the DI technology have made the licensing prohibitively expensive, whereas 4 stroke patents all expired over 50 years ago.

I enjoy all things 2 stroke. I’ll never forget the garbage i heard during the first season of 4 strokes in MotoGP. All season long i heard about the “amazing” and “technologically advanced” 4 strokes. But in reality the only bikes to beat the 500′s that year were the 5 cylinder Honda RC211V’s – with double displacement and an extra cylinder! That’s the enormous advantage it took to bring down the 2 strokes!! They should have just retired the strokers in dignity without letting bikes with more than twice the engine take them down. Shameful. Makes you think that there was real hatred out there for the 2 stroke, which is silly considering we’re talking about engines lol!

Anyway, so those are some of my thoughts on the whole 2 stroke thing. Thanks!

Chris

By motoman465 on November 22nd, 2009 at 10:59 am

I agree with everything that has been said about this article, but a few things I am a little curious about.

First, Chris2T mentioned Roger Decoster. Is he a sell-out? He carries quite a bit of weight with Suzuki. Is he trying to do anything to help the situation or is he just going right along with the four stroke snowballing?

Also, Chris2T mentioned how the supporters of four strokes are heralding their reliability and superior torgue. I have owned my 1982 Yamaha IT465 for nearly a decade now. I have done one top-end on it, replaced the clutch, and little else other than routine maintenance. I once ran the same plug for three years and only changed it because I thought it was time. When Dirt Bike Magazine tested the IT465 against the KDX420 they asked who needs a four stroke? Referring to the low-end power of the IT. I was in a mud race at Broome last month and was letting the RPM’s get so low in one corner I thought for sure it would stall. I just rolled the throttle on and it never hesitated.

Like everyone is saying if the four stroke competed against a two stroke of the same displacement the four stroke would go down. Don’t compare a 250 2T to a 450 4T. Compare open bikes to open bikes!

In regards to this statement;
“Regarding direct-injection 2 strokes. I have been patiently waiting for years now to see a mass produced DI 2 stroke, and I can’t figure out what the delay is. On one hand, Aprilia has offered the 50cc Ditech scooter for over a decade so I thought maybe the direct-injection system only works on small engines. Yet Evinrude has produced 3.1 liter V6 outboard engines with DI for over a decade also so it can’t be a size thing. My guess is that the patent holders to the DI technology have made the licensing prohibitively expensive, whereas 4 stroke patents all expired over 50 years ago.”

You along with many others are waiting the release of direct injection two stroke engines. I was wondering what the delay is as well, since DI is available on outboards, snowmobiles and scooters and not on MX machines.

Then it hit me, for those applications throttle control is not nearly as important as motocross. For the most part in those applications they just accelerate up to full speed and run there. An MX bike accelerates , slows down, accelerates, etc, etc.

We have heard first hand accounts of riders testing fuel-injection on two strokes, these folks were sworn to secrecy by the respective manufacturers and would not even confirm if they were FI or DI. But they did say they are testing them and they work really well.

The patents for the DI system are held by Orbital in Australia. I have heard some crazy numbers bandied about when the cost of licensing is brought up. This may indeed be the hurdle keeping these machines off the showroom floor.

My guess is that the manufacturers working on this technology want to ensure that FI/DI will work under all circumstances and will be heralded as a great advance in technology and become a must have for MX. With large amounts of money at stake they can not afford to release a bike that didn’t live up to the very high expectations of the buying public.

They would also want to ensure these machines would actually sell, so they can recoup their R&D expenses.

It’ll be very interesting to see the machines the factories bring out for the new 125 European Championships in April. My guess is that we’ll see some interesting technology on those bikes. Although they’ll probably be tightly under wraps before that first race.

Friends of twostrokes are friends of motocross =)

Heres an essae about emerging 2t technology.
Its long and sometimes very technical, but candy for the soul.

I can’t imagine motocross without two strokes. The sound, the smell, the engine, everything i love in two strokes. I’m like you and I try to fight to keep two strokes motocross. It’s why i’ve bought a beautiful RM 125 2010 from suzuki, it’s a very great bike and it’s sure i’ll never change it for 4 strokes RM-Z 250. Long lives two strokes motocross !!!!!!!!
Thanks for your site
Braaaap !

Hey Fred125…

We want to see photos of your new bike!! Is it really a 2010 model?

Where do you live? Have you ridden it yet?

Inquiring minds would like to know! :-)

By fred125 on November 28th, 2009 at 1:12 pm

Hey Johnnicholas
I live in France !
The bike is really a 2010 but unfortunately (or not!), the model is the same as the 2008. I received it last week end and i’ve not ridden it yet because of heavy rain here and tracks closed.
The bike is really beautiful with its sparkling yellow, excel rims, Renthal fatbar, very good position, the weight (pretty with 87kg!), everything is perfect on, just have to wait for my rockstar makita graphic kit !!!
