AMA clarifies proposed Youth racing rule changes for 2007
The AMA is clarifying two proposed rules changes that could affect motocross and other Youth racing classes for 2007.

Many youth racers and their parents have contacted the AMA recently about proposals approved in early October by the AMA Congress, the Association's rules-making body for amateur racing and road-riding events. Two proposals have drawn the most questions and comments:

A change in displacement limits in certain classes in motocross only, which would eliminate different displacement limits between four-stroke and two-stroke machines.
Changes to Youth regulations that would allow four-stroke motorcycles up to 150cc (such as the newly introduced Honda CRF150R) to compete in Super Mini and "schoolboy" 12-15 classes.
All competitors should remember that rules changes proposed by the AMA Congress do not take effect until or unless they are approved by the AMA Board of Directors. The AMA Board will next meet on November 18-19 to consider proposals from Congress, among other business. Unless otherwise stated, rules approved by the AMA Board will take effect February 15, 2007.

The final decision made by the AMA Board on these rules will be posted on this website.

Proposed changes

Here is a summary of the two rules changes proposed by AMA Congress that have drawn the most questions:

In motocross only, new displacement limits would be applied to class 2 (100cc-144cc), class 3 (145cc-250cc) and class 4 (251cc and up). This means that both two-stroke and four-stroke motorcycles would be limited to the same maximum displacement and the limits would apply to A, B and C classes.
In Youth racing, the displacement limits would be changed in the Super Mini (12-15) and Class 16 (86cc-125cc age 12-15) classes to allow 75cc-150cc four-stroke motorcycles (such as the Honda CRF150R), in addition to the current two-stroke limits. In Super Mini, the maximum displacement for two-strokes would be increased to 112cc.
AMA members can best influence future rules-making processed by contacting their representatives in the AMA Congress. You can find your Congress representative online. Comments may also be sent to AMA staff, who will present Congress' proposals to the Board, by using the contact form on this website.

It won't happen. 250 two stokes make 10 more horsepower and way more torque than a 250f. Yeah, that sure is a lot more fair

you made it sound like it had already passed in your other posts.

And why do you hate 4-strokes so much?

Ride them stock, put a "Q" silencer on them and they still do everything better than a two stroke, are still fun to ride, and they are still cheep!

Guess what? 2-strokes aren't cheep either if you dump as much aftermarket junk into them as most people do their 4-strokes.

[crfdude3591]

doubt it or believe it, it is gonna happen. it passed the congress unanomiously with a 53-0 vote and no complaints from manufacturers. it is expected to pass the board unanomously again in november.

4-strokes do not do everything better. why does it take 80-100% more cc's to make equivalent horsepower then? why do 4-strokes have more moving parts and a more complicated firing system? 4-strokes are old technology. they have been around much longer than 2-strokes.

2-strokes arent cheaper in the short run, yes. but when a 4-stroke blows up, you might as well buy a new bike. the initial cost is also more expensive, as well as parts, service and accessories.

a "Q" silencer isnt enough either. they will still pe around 96db, which is very loud and the sound carries too. the fim recently lowered their sound limit to 94db for the '08 racing season (they also use a diffferent method of measure). it is predicted that the ama will take this rulle on too.

btw - i dont hate 4-strokes, i just dont believe that the current advantage they recieve is very unfair, and the big, heavy, outdated machines dont belong on the track in our sport.

dude alls u do is complain about the fourstrokes whats the point?
its the best thing out there right now get over it dude

[crfdude3591]

im just trying to inform people that care about what they will be riding next year.
and i they arent the best thing. but im not going to argue any more. believe what you want, but it may not be the truth

"2-strokes arent cheaper in the short run, yes. but when a 4-stroke blows up, you might as well buy a new bike. the initial cost is also more expensive, as well as parts, service and accessories."

How can two-strokes cost more in the short run, but have a cheaper initial cost, cheaper parts, and cheeper service and accessories than four strokes? If you learn to take care of them yourself and leave them stock they as cheap to ride as 2-strokes.

And if the ama takes on the 94db rule like you say than Bam, One less complaint about 4 strokes! They will still be easier to ride and more tractible (if that is a word) than a 2-stroke.


"4-strokes are old technology. they have been around much longer than 2-strokes."

Are you trying to make a point? RC has been around for longer than me I guess that means that he isn't as good?

Oh and find me a race ready 2-sroke on the track that is only 94db. Yeah, good luck with that one.

I think it's time has come. If 4-strokes are better than 2-strokes than they should run the same displacement. If they can't hang with them, than they aren't better after all.
We will see how many riders win at Lorreta Lynns next year on 250Fs.

ABSOLUTELY. The beauty of all this is that we now have 3 classes again. Hail the return of open bikes ;-)

Same CC's? Hahaha..... 4 strokes are overweight & under powered. Their only saving grace is that they are easier for lesser skilled riders to ride.

Sounds like the four stoke guys are getting nervous about losing there double displacement advantage!

I will take a 4 stroke 450 over any two-stroke on a motocross track anyday. That is why I bought one!!

And unless they start making a 160 two-stroke or something, not many of the little teeny-boppers that ride the "lites" class are going to be able to handle the 250 2stroke and its abrupt power. So the price will still be just as high because they will be dumping a grand into their two-stroke motors to make them as fast and ridable as the stock 4stroke 250's.

And then if you make the two-stroke as fast, it still is't as ridable. Don't forget that is why people went to the 4 strokes in the first place.
