I agree with Brian.
To me, the Japanese manufacturers tend to build a street bike first and force it to race, especially in AMA/WSB. Obviously Ducati builds there bikes with racing in mind because they know, every superbike they make, will race at some point. Its changing though, the 1098/848 are nowhere near the corse bikes. Everything from frame and swing arm to gear ratio's and compression ratio's are different on the modern corse bikes. In the past, you could get a hold of an R bike, and it would be pretty darn close to the RS version, especially with the 748R, which is very close to the RS model. They've had to dumb the 1098R down a lot and thats just frustrating.
If Ducati were smart, they'd produce a limited edition RACE-ONLY version of the 1098R with no emission crap, track fairings, race gear ratio's, adjustable rear sets, ya know.. stuff that makes a track bike, a track bike. Charge whatever they want, $50k? I mean, who cares what they charge. This way, you don't have to buy an RS, which needs to be re-built every day and you can get out of the box performance direct from Ducati, instead of your local tuner.
