My vote would be for a turbo hayabusa as I like the busa in stock form much more than a liter bike. Between turbo and all motor there is no comparison really. The turbo setups make more power and you can keep the motors to stock displacment and specifications for all purposes. All the "I was in boost and my tire almost came out from me in a corner talk" is from people that don't own turbo and might try and go dive into a corner WOT with one. You can succesfully ride a turbo in a corner just as well as any other bike. The bikes don't build boost unless the throttle is wide open. If you ride into a corner and keep your throttle under control you will be fine. IF you do alot of track riding and street light to street light then maybe an all motor setup is for you but a good rider can still beat you in about 99% of situations on a stage 1 turbo. By the way the turbo's are much more fun and make ALOT more power
