A 3 Speed Grass Track gear kit to fit the original Yamaha case.
The gears in the R1 are the weak point of the drive train, so we have developed a 3 speed gear kit using stronger gears than standard.
The kit comes with new gears & input shaft, we will modify the original output shaft to accept our kit.
It is designed to fit into a standard case with no modifications required.
Ultra tough construction for rough terrain, gears are REM super finished increasing life and reducing friction. This results in core strength of approximately 30% greater than most manufactured gears.
