I think most people have trouble getting off the line quick with the VFR box and tall first gear

I run the gsxr flywheel, i know it's alot more costly, but the difference between the gsxr and standard is massive, but the difference between total loss and gsxr is not that much IMO. and for me i would rather have one less thing to worry about between races (remebering to charge the battery) especially if you have to change wheels or repair damage from an off.
