For Suzuki Vinson 500 (03-09)
New version with complete roller assemblies
A new kit that contains complete drop in roller assemblies. This kit is designed to re-calibrate the shift pattern to help recover some of the losses from installing oversized tires. Bottom and midrange acceleration and performance are greatly improved. Also aids in performance when operating at higher elevations. This kit can be used with stock or oversized tires, however, when used with stock tires at low elevation it can cause a slight loss of top speed.
