Built for riders looking to upgrade a stock 6-speed setup, the Fat 6 Super Gear Kit is assembled into a 6061 billet aluminum big bearing trap door to help reduce flex in high-performance use.
It features straight-cut gear teeth with a 53% increase in width compared to stock for added load capacity and strength, plus a lightened one-piece steel shift drum and aerospace-grade 9310 steel gears.
JIMS® quick shift ring technology helps minimize the annoying clunk when shifting, while gear ratios remain similar to stock with a 1:1 final drive ratio. Compatible with your stock gear selector and requiring no modifications to the case or exhaust mount.
Made in the USA and assembled in JIMS technologically advanced facility.
