...and, just to add:

My 450 makes a corrected 45-48HP at the rear wheel. That's like a true 35 horsepower motorcycle. Do we really need to have steering dampers on that!?!

When we were racing supermoto, we were *not* requiring belly pans.

Bart can speak to this, but basically the purpose of a bellypan is to prevent catastrophic oil release such as that caused by a thrown rod. Multi cylinder motors have the potential to do much more oil spreading than a single, since a single will stop with a busted rod, whereas a 4 cylinder will keep whipping the rod around and carve through the cases.

That's similar to the reasoning behind 5.2.CC. exempting 2-strokes from needing a bellypan.

It's Ray's call, not Tbag's! [-X

Oh man, let's not go there. I really don't want to see protests about someone not having wired pinch bolts or having holes in their leathers. Just tell Ray about it..

I'm just telling ya what the rulebook says... if Ray-Ray want's to deviate, then that's his perogative.

Can't protest a technical infraction FWIW.

Thought 2-strokes were exempted due to the fact they have NO oil in the crank case... :roll:

True, but the problem lies in the fact that MOST two strokes that are road raced already come with a belly pan. Therefore, if you were to race an RZ350, for example, be prepared to get black flagged by corner workers until everyone is on the same page that you aren't required to have one. Dan Qualtaire got fed up enough he ended up making one out of a turkey basting pan. I don't Think Chuck has had any issues with his CR500.

I think most 2 strokes share the cases with their clutches & transmissions, which generally have oil. :roll:
