SHOCKING!

WHAT IT COSTS TO KEEP YOUR MODERN FOUR-STROKE JAPANESE MX BIKE RUNNING!
BY: MATT CUDDY & RICK SIEMAN

As a public service, Superhunky.com brings you a shocking expose’ on how much it costs to rebuild a new four stroke Japanese MX bike. We disguised our voices with hi-tech voice-altering devices (helium balloons) and called a few well known motorcycle shops around the country. We got some scary numbers for what it costs to rebuild just the top end on one of the newer Japanese high-zoot four stroke motocross bikes, 450’s to be exact.

Hold on to your wallets, because the costs are staggering.

I first called a Honda shop in Los Angeles, California. And after inhaling some helium,  I spoke with the service manager. I had a standard set of questions that Rick and I agreed to that seemed to be appropriate.

“Hi, I own a 2008 Honda CRF450R that I bought used, the last ride it started sounding funny, and backfired out of the carb a few times when I was really pushing it. How much will it cost to fix? What’s a new top end cost? How about the head? Can’t I just adjust the valves, bore it and get a new piston, and it’ll run OK again?”

From the other end of the receiver came an exasperated sigh, and the service manager seemed to then read a pre-written set of answers, from a piece of paper perhaps stapled to the wall in his office:

“Oh, that’s a hard one to diagnose without first seeing the bike. You can’t bore out the cylinder, it’s paper thin nikasil coated on a composite cylinder, either you buy a new one, or have the old one re-plated, costs around five hundred bucks. The piston, wrist pin and rings will run you another four hundred dollars.

The titanium valves are the weak point on a CFR450, they don’t bend or break, but shatter and ruin the whole top end, head and all. That costs about two thousand dollars. Then you have the installation, gaskets, labor, anti-freeze, tax, etc. runs about twenty five hundred all-in, ready to go.”

Garsh, that’s a wad of dough there, mister. Think I’ll just dump this thing and buy an old CR500, thanx anyway.” And I hung up.

Outrageous! I could buy a nice used Dodge Dart, and have enough money left over for a years supply of Lucky Lager! What are the Yamakawasuzionda folks thinking? Do they want to give dirt riders heart attacks!? Good Lord Almighty.

It was Rick’s turn, so he called another dealer on the other side of the country, in the Pittsburg area, and asked the same set of questions.

HONDA DEALER PITTSBURGH, PA

I told the service department the following:

“I just bought a 2008 CRF450R and I went down to my buddy’s place in West Virginia where it wasn’t snowing and rode for about two hours. Then I got back firing out of the carb and we heard a bad knock in the top end. We checked and the knocking was in the bottom end, too. I guess I probably need a complete rebuild.  Well, I know it’s hard to get a ballpark total on a rebuild, but what would a guess-timate price be?”

The response:

“Assuming that all the major things need replaced, about $3000 plus should do it.  That would be a piston, rings, rod, gaskets and such … plus the labor.  And that don’t include the trans and clutch.”

I protested:

“I just paid $3200 for this bike!  It ran OK up and down the street, but I only rode it for less than two easy hours.  My buddy has CR 500 and he says he does a top end every few years.  He told me that the new four stroke racers have a short fuse.”

Response:

“Hey, it’s a race bike. You might save a few bucks if you get some non-Honda parts.  But I won’t guarantee those parts.  It’s still gonna cost you about three grand for a rebuild.”

More from me:

“How many hours will you guarantee the rebuilt motor?  What if I do the work myself;   get it bored and put in a new piston and rings? I can do basic mechanical work.”

Response:

“Nobody will guarantee a race bike. You can’t bore the cylinder.  It’s coated with a real thin liner.  If that’s screwed, you’re looking at a new barrel.  Look, these new bikes are really high tech and they ain’t designed to live real long … just go real fast for a while.  If you’re just gonna play ride, then you ought to get a CR500 like your buddy.”

Last from me:

“Well, about how many hours could I figure on out of a fresh motor on my 450?  Roughly.  Just a ballpark … not racing, just out having fun, you know.”

Response:

“I don’t want to give you a hard number, but you can probably figure on 15 or 20 hours. That’s about it.”

Last from me:

“Well, about how many hours could I figure on out of a fresh motor on my 450?  Roughly.  Just a ballpark … not racing, just out having fun, you know.”

Response:

“I don’t want to give you a hard number, but you can probably figure on 15 or 20 hours. That’s about it.”

BLASPHEMY! Fifteen to 20 hours from a dirt bike that costs over eight grand new! What is going on here? Some plot to ruin the sport of dirt biking? That had to be wrong, so I called a Kawasaki dealer right down the street, and asked them the same pre-agreed to set of question:

2010-Kawasaki-KX450Fe-small.jpg

“Hi, service please.”

“Service, how can I help you?”

“I have an ’08 KX450F MX bike that I bought used a couple months ago, and it’s started making funny noises like a low knocking noise, and it’s backfiring out of the exhaust pipe every time I downshift. What could be wrong?”

Service: “Oh, you’ll have to bring it in so we can do a leak-down test on the top end, sounds like it might be worn out.”

“And how much will that cost?”

Service: “Free”

“What if the top ends is shot, how much to fix it?”

Service: “Oh, we’ll take it apart for you, see what’s wrong …might be something simple.”

“ How much for that?”

Service: “Oh, that’s free too…”

“Free?”

Service: “Yes, free.”

“Well I suppose putting the damn thing back together again if free too, since it will cost about three thousand #$&^%$# dollars to fix, right gummo?”

Service: “Err, well…err…um…”

“That’s what I thought!” and slammed the receiver down as hard as someone who was light headed from helium inhalation could muster.

FREE MY ASS! This is a conspiracy! Will it go full circle once again, where we have to buy street bikes and strip ‘em down like the old days, instead of buying one of these exploding cigars?

Oh I was on a roll now! Who to call next? The Suzuki shop! Yes!

TO BE CONTINUED

This is just the tip of the proverbial iceberg. I was perusing Dirt Bike magazine and saw that new 450 MXers are going for right around eight grand sitting on the showroom floor. So that means with dealer prep and set up, taxes, off-road registration and other graft included, a new 450 dirt bike will cost around nine thousand hard earned Yankee dollars strapped down in the back of your truck.

To think that you can only get fifteen to twenty hours of moderate riding out of one of these technical marvels before a rebuild is in order, is outrageous. And it’s worse on the smaller bikes, like the 250 four strikers that live at 13,000 rpm all day, and explode even worse than the big ones.

This is the first installment on a subject that no one else wants to talk about, the throw-away MX bike. We’re going to dig deeper into this controversial issue, and hopefully be able to make some sense why it happened, and what you, the hard core dirt biker can do about it. Stay tuned.

I agree the prices are outrageous. But honda designs these parts to fail every 20 hours. The make a percentage on every part they sell to you…. It’s all about making money now. Like if you go to a dealer to buy some sprocket bolts, they want about $35, sometimes dealers don’t even include the nuts to them! I go around the corner to a hardware store and but the same exact bolts besides having a gold plating on them, for $4.50…. (For a BAG of them!)

It used to be about high value, and good customer care. Now it’s about having big fat wallets, and only decent customer care as long as you pay them to help you….

Looking to buy a used 2003-2007 YZ/CR/RM 250 give her a wash and a fresh piston just so I don’t feel guilty. Good as new.

By bleake637 on February 3rd, 2010 at 5:30 pm

That’s no joke. My poor delusional friend has an ‘08 KTM 450 that went “thunk” the other day. Bent the rod, trashed the head, etc. He took it to a dealer and after looking at it they suggested just parting it out and quoted him $3200 to try and fix it granted the tranny was ok, which it probably isn’t. I told him he needs a CR500 engine for the frame now! I’ll take my cheap and easy YZ250 any day thank you.

By 357 Racing on February 3rd, 2010 at 6:11 pm

Just blew my 88cc crf50 motor up. Dropped a valve, valves, head, piston, cylinder are paper weights now. My other pit bike motor is now buring oil, needs new valve seals.

My 10 year old 2-stroke weed whacker still running strong = priceless

I hava an 08 YZ250. I am very guilty of lack of maintainance since I have not raced in years. I spend my time on the kids bikes and ignore my own. My bike has many hours on it and by compression check there is still no reason to rebuild yet. Used to be 4t was indestructable and 2t was high maintainance. Tables have turned and the 2 stroke is the longest lasting cheapest most high powered racing engine you can possibley run. I own 08 yz250, 03 kx65, 08 kx85, 87 cr500, and an 05 230 honda 4t 4 wheeler. Yes the 4 wheeler is most reliable but crank the HP up and then it is junk. Any 4 strokes going to Croom this weekend that want to look at my rear fender???

By irace2tmotos on February 5th, 2010 at 11:23 am

I know it has been done before, but the prices of rebuilding a two stroke should be shown to all.

There still is and will never be one of these overpriced, over weight, ill handling, run for 1 week 4 junks in my toy box. I have had motorcycles since 1970. Lot’s of them! My 1994 Suzuki DR 350 had 8900 miles on it and never had the top end off yet, still runs strong.

That’s funny the one dealer says “hey it’s a race bike”. I see the same dusty 4 junks sitting in the same place on my local dealers showroom every time I visit. I laugh really hard as I walk by on my way to the parts counter to buy parts for the older 2 strokes I’m totally rebuilding for less than 3 grand… LOL. I can totally rebuild older 2 strokes all day that will out last, thrill me when I hit the gas, and out run the new 4 brokes.

A 500 AF will roost all over a new 4 joke. Every time I visit my dealer for parts for my 2 strokes, I tell him I will never buy the products he is selling now, and other dealers who sell Service Honda, KTM, Gas Gas, TM, Ossa, Maico and Yamaha, will get my dollars.

DO NOT BUY THESE FAULTY PRODUCTS, IF THEY WERE AUTOS THEY WOULD BE RECALLED BY THE CONSUMER PRODUCT SAFETY COMM,among other groups, in fact I’m sending info to them for exactly this concern. These products are a safety hazard, and a rip off.

Let’s get thew REAL word out! Either build good products the consumer will buy, bring back the 2 strokes, or go out of business!

Check out the new Gas Gas line!

So a 450F lasts 15-20 hours. How long does a 250 2-stroke last?

By JohnNicholas on February 5th, 2010 at 11:14 pm

2STROKERREVOLUTION – remember that the 15-20 hours is the recommended service interval on the four-stroke. For the YZ250 two stroke, Yamaha recommends replacing the rings after every third race and the piston every fifth race.

In actual practice the difference will be in how you use your machine. If you are a hard core racer competing in the Nationals you service schedule would be much more often than a trail rider on the same bike. I know guys with YZ250’s that race motocross and only change the piston and rings once a year!

In Pro Racing the factories change the motor after every event and sometimes after practice! Costs for four-stroke motors runs between $12,000. and $25,000 depending on who you are talking to.

If you were to race a two-stroke at the Pro level you could easily rebuild a complete motor for less than $2,000.00 per event.

That is a huge difference in a racing investment, no wonder the factories are having so much trouble getting sponsors to support this kind of costly racing!

The sad part is that many people base their buying decisions on a bike based on what wins in Pro Motocross. Even if they don’t race motocross…

Unfortunately the guys that actually buy the bikes are beginning to catch on. At first I’m sure some of them just thought they were having bad luck, but after blowing up multiple motors, they got the picture…

Hopefully they decided to buy two-strokes instead of taking up another sport!!

By 2STROKEREVOLUTION on February 9th, 2010 at 1:42 am

So if you race a 250 2-stroke, a 450F, and a 250F in motocross at the same pace what would be the expected life of each engine?

Just piston and rings? Valves? Full rebuild? Clutch?

By Paul on February 13th, 2010 at 3:05 pm

About 10 years ago I heard from a very reliable source of a test conducted with the ‘big 4′ 250 MX engines. The engines were set to run on a dyno at redline, at Max HP, approx. 7500RPM, and left in the room until the motor failed. The Honda CR 250 held up the longest at over 80 hours! That is 80 hours of top revs without a break. How long would you bet on a 250/450F to last in that same test?
So far, I am on my 10th season of play riding, racing on my 81 490 Maico since rebuilding it 1999. I took it apart last season to paint it and the motor did not need any new parts. Nothing! I ride vet expert classes and do not baby the bike like some of my 450F riding buddies. I’ve seen 4-strokers blow apart where peices scatter all around the bike.

So I just rebuilt my ‘02 KX250, guess how much it cost just for the top end with gaskets…. $230 (Canadian $$$) I could have gotten a full rebuild with the crank and gaskets for $480. The old girl was still running strong and I used to race it when it was brand new. When I took the piston out there where no marks on the cylinder or the piston. I could have just threw a new set of rings in and it would have been good, but I figured I’m already in there I may as well do the whole top end. I was really close to buying a KLX450 cause I could have gotten it for $5600 but I’m glad I didn’t. Plus 4 jokes sound like crap when you pipe them up.

By elementx665 on March 27th, 2010 at 1:05 am

my 02 kx250 has never had a topend or anything. just new spark plugs thats it and still runs like a beast.
