if it helps, y not think of it as a race kit that comes on wheels instead of in boxes?

Doncha wonder about the real economics of XBRR? They're selling for $30K, but with only 50 to be sold and with Buell's financial commitment to racing, they might actually cost twice that much to build, especially if development costs were included. So the Lucky Fifty get a hella swell racebike for a fraction of what it would cost to build up from a streetbike. Meanwhile, competitors on other brands--taking the route implicit in the rules--pay full retail to turn their streetbikes into racebikes and end up at a disadvantage to the factory-subsidized XBRR.

Re: One Man's Opinion: Hardly Legal, Son

A big difference with Indy '94 was that the entrant, Roger Penske, tried to point out the pushrod engine rule loophole to the sanctioning body, USAC. If you don't plug this hole, I'm gonna hafta build a damn motor to take advantage of it, Roger warned. They didn't; he did.

Now that this previously undiscovered FX loophole has been exposed, I wonder if others will take advantage of it. Elsewhere, someone opined that Ducati might be able to wrap their air-cooled motor in a 999 chassis and sell it as a production racer. Punched out to 1340cc, it would leave the Buells--and everyone else--in the dust.

Are you referring to Ducati?

Pushrods aren't mentioned in the AMA FX rules, so a Ducati SS1000 would be treated the same as a Buell XB12R.
AMA Formula Xtreme motorcycles are based on production fourstroke street motorcycles. The motorcycles in this class must have the following engine displacements:

450cc - 600cc 4-stroke multi cylinders

595cc - 750cc 4-stroke liquid-cooled twin cylinders

850cc - 1350cc 4-stroke air-cooled twin cylinders...

Twin-cylinder air-cooled motorcycles:

Engine modifications are unlimited
