Rouleau 8X10

This genuine Honda 8x10mm roller is a key component in the centrifugal clutch and starter motor system of models like the CT70, ATC70, TRX70, and C70.

Replace these rollers when they’re no longer perfectly round, worn rollers can disrupt clutch timing, affecting both starting performance and acceleration. These rollers enable smooth clutch engagement based on engine RPM, critical for proper operation of the starter motor and centrifugal clutch.

As an original Honda part, 91101-039-010 offers long-lasting quality and is essential during clutch overhauls. For consistent engine response and drivetrain durability, always choose OEM replacement parts.
