The transmission components of your scooter transmit the engine's power to the rear wheel so they need to be in optimum condition. Here you'll find common wear parts such as belts, roller weights, clutches and clutch springs. Maybe you want to make better use of your engine's power? We have transmission tuning parts too, stiffer springs, variators with agressive ramp angles, rollers in different weights, anything you could need to tune your drivetrain to your heart's content.
