EVO Powersports CFMOTO U10 XR Series Primary Clutch Bolt
The EVO Powersports (EVP) XR Series Primary Clutch Bolt is an essential fail-safe for the CFMOTO U10. The factory clutch bolt has a relatively small minor diameter, which makes it prone to shearing if the clutch slips on the crankshaft. When the OEM bolt breaks, the resulting damage to the crankshaft, housing, and secondary clutch can be catastrophic.
To solve this, EVP collaborated with ARP, the world leader in high-performance fasteners, to create a bolt that allows for significantly higher hold-down torque. This increased clamping force prevents the clutch from rotating independently of the crank. As part of the XR (Xtreme Racing) Series, this bolt has been punished in drag, desert, and short-course racing to ensure it remains the strongest link in your drivetrain.
