NO new car marketed in the United States has been powered by a two-stroke engine since Saab phased out its hard-to-housebreak 3-cylinder in the late 1960s, when federal air pollution laws were taking hold. And with images from Eastern Europe of belching Trabants still fresh, there hasn’t been much of a clamor for a two-stroke revival, either.

The following essay is the result of an e-mail that I received, a high school student asked some questions about the differences between two-strokes and four-strokes. After e-mailing some information, this is the end result as written by a 10th grader for one of her classes.

Have you ever heard the statement “that guy just has “it”? Sort of like how James Stewart and Ricky Carmichael have “it”? What exactly is this “it”? Sometimes it’s a group, sometimes it’s a nuance, a nebulous factor that is difficult to quantify. In this discussion, the “it” is off-road motorcycling. We will look at just what state (condition) is “it” in.
I’m not big into numbers. They have their purpose, but there is more to life that cold hard statistics. And, if you live by stats, you will just as surely die with and by them. I’ve sat back and watched as my customers have shot themselves in the foot with numbers. They went with the numbers and left performance on the table; cost themselves money and some even irritated me to the point where I got rid of them as customers. Principle over money is my motto. My point is this: there is a big picture out there, and those who control off-road motorcycling, and its future, well, they are flat missing it.

We have met the enemy and he is us.
Imagine that a major manufacturer could build an engine that was eight pounds lighter than the typical powerplant, revved quicker, produced ten more horsepower (per quarter liter), had one-tenth the moving parts, cost less to maintain, and could be rebuilt for a quarter of the price of a modern engine. Wouldn’t that be wonderful? Shouldn’t that designer win the Nobel prize?

You may or may not have noticed, but in my area, as well as many others in the United States, you can buy a used 4-stroke dirt bike of the same year as a 2-stroke for same price if not cheaper. Why is this, you may ask? There are many factors as to why this is happening. First of all, you have to realize that an “Asking price” is NOT the same as a “Selling price” on almost every occasion. While there are many people asking “X” amount of dollars for a their 2007 KX250F, they are almost always selling it for less, even if their price is “Firm”.

The infamous sound of the new two stroke Maico will soon be reverberating around Australia with news that the brand is about to make a major come back down under through Australian company Maico Australia.
After several months of contractual negotiations and logistical arrangements through distributors Maico U.K. an exclusive distribution deal will see the complete range of handmade two strokes will be heading for the sunny Gold Coast shores over the next few months.

Where did the 500?s go? These monster two-stroke machines used to rock the race courses of America with a thunderous roar. Anyone who was anyone strove to graduate to the Open class. The 125 class was for schoolboys, and the 250 class was for paperboys-the 500?s were for men. The men might still be around, but the crackling cakle of the 500cc two-stroke machinery has faded away.
Today, the 500 class is all but forgotten. With the exception of the Service Cycle CR500AF and KX500AF, there are no classes for them in local racing, and not a single highfalutin” AMA National factory rider racing today has ever raced a true-to-life Open bike. It wasn’t always so.

Until someone builds a production 4 stroke MX bike that will outpull my 21 year old CR500, I call this 4 stroke revolution a failure.
by JohnNicholas on 11/13/2008
I don’t know how I found your site I found it by accident but it’s a great site. I bought my first CR250R because they were cheaper since people were unloading to the 4 stroke garbage. I heard they required more talent to ride and I was up to the challenge.
I had the intention to purchase a 450 in 2 years but after riding my cr250 for 3 years I have no desire to get a four stroke. Everything your saying is right. People who blow off 2 strokes don’t know anything about motorcycles. I know plenty of racers that run 4 strokes but as soon as the race is over they run back to their 2 strokes because they love the bikes.

Travis Pastrana is my 2stroke hero. Hands Down. It could be because of all the stories I’ve heard over the years, growing up so close to where he lived or maybe the fact that he has shown his loyalty to the fun, freedom, and sound of his RM Or maybe, its just his NO FUCKS GIVEN attitude while still being the nicest, most down to earth guy. All about the fun, All about 2strokes. So what do I want to see in a race where anything goes, where there is No unfair AMA displacement rules, No lets tear down peoples bikes that we know cant afford to have factory built motors..No dictating what bikes we see on tv…… Mr. TP199

“Join the movement before it’s too late.”
With so much attention focused on the four-stroke and many folks claiming the end of two-strokes is near, reading something as strong and supportive in a mainstream magazine is a breath of fresh air.

This is not a new debate by any means, the boating industry was one of the first to address the disparity between the two and four.
In boating you have a choice between two stroke fuel injection or four stroke. At least they have a choice!

Following countless test sessions, although realistically it’s that good, only one forty minute stint was needed to realise that this just had to be standard equipment for next year, here is the first picture of the new shock absorber designed and manufactured specifically for the 2011 M.M.X.
Weighing in at approximately one and a half kilo’s less that the previous Reiger shock; the all new unit features a wealth of adjustment, with 50 click settings on the rebound, 45 clicks on the high speed compression, and 25 on the low speed compression as standard. With the top end of the shock beautifully manufactured from Billet and a coated rod, it is expected that the production models will come with an anodised reservoir and will be manufactured to suit the weight of each individual rider when the customer orders his or her bike.

The two-stroke highlight of this years Loretta Lynn’s Amateur Championship was the performance put in by 42 year old David Jones in the Vet B/C 30 Plus class. The Cleveland, Ohio resident rode the wheels off of his 2004 Kawasaki KX125 to take the overall, winning the coveted National Championship.
David has participated at Loretta Lynn’s for more than ten years! His previous best finish was in 1999 with a 5th place. Over the past few years he had some bad luck with crashes, sometimes not making it past the third turn before going down.
by JohnNicholas on 09/24/2009
In our local area the resurgence of two-strokes continues to grow. Sure there has been great debate about which is better… two or four. The truth is that without the displacement advantage the four-stroke would never have made the advances into motocross racing.
Just the fact that the manufacturers are concerned that a rogue privateer on a two-stroke just might be able to beat their factory backed racers should tell the complete tale.

The following Article appeared in the September issue of DirtRider DownUnder magazine as a guest column. Written by Terry Baisley the Vice President Of Sales for Fly Racing. Enjoy!
I long for the days of the good old two-stroke motorcycle. When you could rebuild a top-end by yourself without having to have the knowledge of an engineer to figure out where all the pieces went and how they fit back together. When the biggest challenge was to remember to put a rag over the crankcase so you didn’t drop a circle-clip ‘downstairs’.

I love two-strokes! I race them, fix them, restore them and promote them. There are always a heard of two-stroke machines in my workshop every month.
One problem when fixing or restoring two-stroke bikes is rusty exhaust pipes They are such a pain to get cleaned up. I’ve tried sanding them which takes too long, requires hours and a ton of elbow grease.
by JohnNicholas on 09/05/2008
Not to start any conspiracy theories or anything, but I have heard told in most of the US Motocross media that some of the Japanese manufacturers are no longer making any two strokes. Sure Yamaha and KTM are still in the game here is the good ‘ol USA, but the word is that Honda and Kawasaki dropped them completely.
Or is it????
by JohnNicholas on 09/04/2009
If there was ever a mis-conception to be perpetrated on the motocross public, it’s the fabrication that the four-stroke is in some way superior to the two-stroke. Now before we dive into what has turned into an endless debate, let’s get everyone on the same page first.
The demise of the two-stroke in motocross is politically motivated, plain and simple. There are reasons for this that we will never be privy to. mostly why this insane change was brought about in the first place.
by Chris Barker on 09/03/2008
Where to start?
OK You have guessed it I have a passion for 2 strokes, and having raced them for many years and being involved in the MX industry since 1992. I was seeing a dramatic change taking place, the new breed of oversized and overly noisy 4st’s had been given such an unfair advantage class wise it almost destroyed the humble 125 especially, add to this the huge costs involved in their up-keep things were changing and a change I was not happy with, so after a few beers in the pub one night with some fellow 125 riders I set about making a proper 125cc class.
by JohnNicholas on 08/25/2008
Before you go to the races it is a wise idea to make sure all your money spent and all that effort involved will add up to great finish and a fun day! Many riders, maybe just starting out, or seasoned vets and pros forget about a very important part of their high tech racing machines….The gasoline! Yes, that expensive petroleum fluid that makes your bike rip IS important!
Whether it be really expensive racing fuel or just really expensive kinda junky fuel from a local gas station (heaven forbid), the correct fuel temperature will make a difference in the performance of your bike when starting the race!

We hear this scenario way to often. People getting priced out of this sport is reality. Some of these people are very talented, and are faster and more dedicated than the competition. Where are they? They can’t afford the rebuild and maintenance cost’s associated with racing a Four Stroke at the professional (or Semi) level.

A long time TSM supporter and reader Bill T. posted the following photos on our forum. In addition to taking photos, he spoke with each of these brave racers and added a short description to go along with each photo.

In this new feature section of the TSM site we’ll be introducing you to racers and industry people. These interview answers are not edited or changed for content, only spelling and punctuation will be corrected. So what you get is down to earth answers direct from the folks being interviewed.
In this edition we introduce Randall Everett. If you have been a reader of the site you may have watched Randall pounding out some laps on his YZ250 in the feature video. It was so amazing hearing the way Randall rides that bike that we figured we’d get in touch with him and ask some questions.

Believe it or not, there is more than one way around a track.
There was a time when the only people who rode four-strokes were grizzled old prospectors tooling around the Southwestern desert (And some guy named Scott Summers) No more! The four-stroke has replaced the two-stroke. The two-stroke had been the bread an butter machine of the last 40 years. The vast majority of riders racing today learned how to ride on a 50cc, 85cc or 125cc two-stroke. Then when they decided to make the step up to the big time, they switched to a valve-and-cam machine.

KTM has announced record 2008 sales of 25,000 two-stroke bikes and says it sees no end to the high-performance two-stroke. Australian firm Orbital is testing a 200bhp, fully emissions-compliant 1000cc twin that’s lighter and more fuel efficient than any rival four-stroke. Aprilia craves an accessible performance middleweight, says it could easily render its seminal RS250 Euro-3 compliant and has twice already come close to releasing such a bike. R&D departments in Europe, Asia and North America are arriving at the same conclusion: everything you know about two-strokes is wrong, and their revenge against the four-stroke is imminent.

This berating may be viewed as some random individual who is voicing his singular and own misguided opinion. However, it is a letter from a MX fan that did get around the circuits, and did talk and listen to a lot of parents. These are the very parents that the next generations of MX fans and riders are built on. The people who are the reason MX have the support of sponsors like Redbull, Monster Energy just to mention a few. These are the same parents who are purchasing the bikes, gear and are paying the bills to keep those very same bikes and events running.
I am NOT a lone voice or a SINGLE opinion. There are many parents and 25 year old pilots, who no longer want to spend the vast amounts of dollars required to simply race and maintain a modern 4 stroke motor.

After reading the MXA Online article titled “NASCAR Race Teams take a Financial Hit, Could Motocross Teams Be Next” I decided to weigh in on the two stroke slant on the cost of motocross racing.
As stated in the MXA article “the motorcycle manufacturers have footed the whole bill for their racing efforts over the last 40 years.” This will not be the case in the coming years. In fact starting as early as 2010 we will see at least one if not more major manufacturers dropping their factory backed racing efforts.

I have been riding regularly for the past six to seven years. I progressed from the 80 to the 85 then started riding a 250f. After riding and racing the 250f for almost five years, I was ready for a new bike. I really excelled on the 250f and I really think/thought it was a great bike. By that time I was competitive in the C class on the AMA level.
The bike purchase decision was an extremely tough one. It was the beginning of this year when I started looking and there were just so many options. I was really looking at buying the 2009 CRF450R, because i was coming off of a Honda, and I really wanted more power. I am a very thorough person when checking out a purchase, and buying a new dirt bike was a high priority. After enduring the 2009 bikes being released and even then waiting on the tests to come out. (I usually check all the bike tests and comparisons to help me choose, I particularly think MXA has a good brain on bike tests)

Hey guys… Father’s day is coming up. And what better way to celebrate than with a nice comfy chair. Of course for any right minded motocross racer that chair should have wheels and while you’re at it add a motor to move you around.
These things are so strange that they are a must have. Can you imagine having these in the man cave (some call it a garage) and holding races with your best buds?

The past few weeks has been a blast if you’re a two stroke motocross fan. A few (former?) pro racers showed up at some local tracks on their two stroke machines.
A few weeks ago Travis Pastrana showed up at High Point Raceway on his Cernics Suzuki RM250. There is not a lot of information about this race but here are a few photos. Travis races hard with style and grace. Pure poetry in motion on a motocross bike.

This story is about my son “Lalo.” Lalo got his first motorcycle when he was 12…a 1980 XR200. He picked-up riding naturally, but complained that the XR was too slow. For his 14th b-day we gave him my old 2000 YZ125. After some “relearning” what a clutch was really for, he began to really rip on his 2-smoker. He did so well, that last year we got him a 1995 CR250. Here is where we begin……

Over the past few months many interviews with the Super Stars of Motocross seem to contain a question about two-strokes. Of course asking them what their thoughts are about them. Kind of a loaded question.
As an example, here is one that was posted on Vital MX by MXEditor – Sean Goulart where he interviewed James Stewart at the Fuel TV Studios in NYC.

Over the past few years the media seems to have coined new terms to apply to two-stroke motocross machines. When the two-stroke is mentioned words like vintage and nostalgic seem to pop up. Everywhere from message board users to Ralph Sheehan and Jeff Emig on Speed Channel seem to have gotten the “memo”.
How can this be?

For 2013, TSM has started putting efforts into running a pro race team. To get our feet wet we put together a YZ 250 for Daytona SX piloted by Ryan Smith #831. We had very limited time for bike/rider prep, so we did what we could. It was more of a team building effort than anything else. The time ran out fast, the YZ 250 came together nicely after some delays and backorders.

After last week’s polls, it looks like our wheels will shine with red hubs and black rims, Charles will be getting to work polishing the swingarm, and white plastics will be the backdrop for some killer graphics. After hours of sandblasting, the parts are being powder coated to look brand new. Very Impressive, Please definitely check out the build pictures in the forum. Pretty soon what was just taken apart, will start to be reassembled. Keep a watch on the forum, some new polls will be posted in the next couple of days.
The motor has been shipped off to Eric Gorr and Forward Motion, who had signed on as a bike sponsor and has now signed on to become a TSM site sponsor. In addition to Forward Motion, Motocrosstracks.com and Lineman MX Training have also joined the TSM Sponsors Family. Please check out their websites and be sure to follow them on all social networks.

When I woke up, the thought “how can we gather more support for the two-stroke”, ran through my sleepy brain.
While it’s true that Two Stroke Motocross.com is not entirely responsible for the shift happening in motocross as we speak, the tide is changing. I hope in some way that the stories, articles, tests and press releases published on TSM have helped.

Up until last year I had always owned two stroke dirt bikes. Vintage Can-Am’s, Suzuki PE’s as well as more modern RM’s were the only bikes in my barn. The old ones were for vintage racing and the newer ones were for Hare Scramble racing and just enjoying the ride. For a very long time a 1990 RM250 called my barn home and for good reason, it fit me like a glove and at the zing of its exhaust note many four strokes met their match. Even bikes 10 or 12 years newer ate its dust, I’m sure that a better rider for them would have changed the results some. But we are talking about trails that I knew so well that I could ride them at speed in failing daylight.

Our first poll is up under our forum! Pretty basic to start with, but without it you wouldn’t have much to ride on. A color needs to be chosen for the frame. Your choices will be Red, Black, White, or Silver. The frame will be powdercoated the most voted upon color, courtesy of Power Play Motorsports. Just a few reminders: You must sign up for our forum to be eligible to vote and You will only be allowed to vote once. Polls will be posted on Wednesdays and running till Sunday. The results of the Polls will be posted on Mondays in the forum. Happy Voting! Vote Here.
TSM has been abuzz with some exciting news! TSM has teamed up with Eric Gorr and his company Forward Motion to make this worn out 125, a 144 work of art. In case you’ve been living under a rock and are unfamiliar with the talented Mr. Gorr, he is the author of the Motocross & Off-Road Performance Handbooks as well as several specialized publications. I’ve even heard some refer to him as a God. I would highly suggest checking out the bike build Eric teamed up with Service Honda on, http://www.eric-gorr.com/. So, it looks like we have a motor!

First off, I would like to thank everyone for the “well wishes” Charles has received after is wreck this past weekend. While still healing, of course he is busy with all types of ideas for the future of TSM. We really feel our two-stroke community is more than just an online website and we have all of our loyal readers to thank for that.
One of the ideas being discussed is TSM RACING. This possibility seems closer to a reality and the ball has started to roll. TSM is building a bike and we want YOU to help. We are starting with a 2001 YZ125 stripped down practically stock. Throughout the build we will be taking polls and asking our readers for their ideas and suggestions on what parts should be used. We will even gladly take donations of parts. Our goal is to have a bike that is more than just a company sponsored bike, we want a two-stroke family built bike.

I just bought my first 2-stroke bike a few months ago. Its a 2005 KTM 250 EXC. I’ve always preferred 4-strokes because they lack the “hit” and I always thought they had more low-end. I was ready to buy a 450 4-stroke but started looking into 2-strokes. The more I researched, the more I learned that 2-strokes can be as good, if not better than 4-strokes in the woods.
The 250 has been great. Its much lighter than a 450, and to my surprise runs well at extremely low rpm. The stall resistance is amazing and the engine lugs as well as any 4-stroke I’ve ridden. It seems that a 4-stroke will flame out before the 2-stroke. I thought I’d miss the engine braking of a 4-stroke, but I’ve never even thought about it on my 250. I think it makes me a better rider.

The sport of Motocross is suffering, the fans are diminishing. Why? Four Strokes.
I’m sure many people will disagree with what I have to say, but most know where I am coming from.
by JohnNicholas on 01/14/2009
Whenever the debate between two strokes and four strokes begins, proponents on both sides bring up various reasons to defend their position.
In many cases, real facts with proof are ignored, misused or misunderstood. At times, the arguments boil down to hearsay. Some of it blatant lies.

Motocross today wouldn’t be very much without the people who capture it on film for the rest of us to see. Without the backroom boys and their cameras, the media content that’s available to us in the 21st century would be strictly limited to whatever we could record on our phones. For this installment of Rider Talk, TSM sat down for a chat with Troy Zeigler, the owner of Elevated Visuals, an action sports media production outfit. Oh, and Troy’s also an avid motocrosser himself.
