johnny x i know exactly what each bike is ! i was saying WHICH WOULD BE BETTER IN THE SMART CAR !!!! which is the gsxr motor , the motor is lighter and its geared better for the street
You can stop PM'ing me copies of all your posts.
The GSXR engine is actually much better suited to track use. The higher rpm power curve and slightly tighter gearing means keeping the engine "on the boil" provides better lap times. The 'busa engine feels lazy compared to the gixxer engine, until you look at the speedo and realize that you're about to blast through 250.
The Smart car chassis is considerably heavier than the motorcycle, and therefore the lower rpm power curve and greater torque of the larger 'busa engine works better. As rrocket said, the weight difference between the two engines is negligible, especially when considering the total weight of the car/engine combination.
As for your comparison of the gixxer and 'busa stating that the liter bike is so much better because it achieves the same (or better) performance despite a 300cc+ disadvantage and has a much lighter chassis, I was pointing out that these two bikes are not alternatives. They are completely different machines with different purposes. The GSXR-1000 is a track bike. The engine revs insanely, the chassis is light and the steering is hair-trigger compared to the larger, heavier Hayabusa. The Hayabusa would be slaughtered on the track, as it is really a street-bike. I like to get out of town on my bikes, and the 1000 is too small and has too aggressive of a riding position for me to spend the day hunting roads with it.
Oh, and don't PM copies of all your posts.
