Moturo 3-shoe clutch water-cooled 37cc Pocket Bike ATV Quad Dirt Bike

Moturo 3-shoe racing clutch for pocket bikes, ATVs, quads, and dirt bikes

The Moturo 3-shoe racing clutch for pocket bikes, ATVs, quads, and dirt bikes (37 to 49 cc) — the tuning component for clean engagement from idle. 75 mm outer diameter, adjustable spring tension, ready for installation.

The clutch is mounted on the crankshaft and transfers torque to the bell housing and thus to the drive sprocket or variator. Three individually adjustable springs determine the RPM at which the shoes engage — higher preload shifts the engagement point upward. 75 mm outer diameter, 10 mm bore with keyway, universal dimensions for standard 37 to 49 cc setups.

Replacement takes about half an hour with a socket wrench set and torque wrench.
