By upgrading to a low ratio first gear you allow faster acceleration and quicker ET's without running out of gear before the end of the track. Also great for land speed racers who want a little help getting off the starting line.
Changes ratio from 2.43 to 2.50 (35 tooth)
*Fits Kawasaki ZX12R 00-05
