For the ultimate in clutching, we look to STM to provide us with an amazing clutch setup configured to your power, tire size, gear reduction, and riding style. The strength of the STM full billet clutches cannot be denied. Remarkable at withstanding aggressive driving. There is strictly no better, more reliable way to put down power. Please note, we do not offer the primary or secondary only in order to get you a bad ass setup that will do exactly what it is supposed to do. If you want to step up to the next level of reliability and clutching, this is the setup for you.
