18T Manual Clutch Assembly for 50cc 70cc 90cc 110cc 125cc Pit Bike ATV

Product Overview

Restore reliable clutch engagement and power transfer with this 18-tooth manual clutch assembly, designed for select 50cc, 70cc, 90cc, 110cc, and 125cc 4-stroke horizontal engines commonly used on pit bikes, dirt bikes, youth ATVs, quads, and mini off-road bikes.

Built for manual clutch applications, this clutch assembly helps solve common issues such as clutch slipping, poor engagement, weak power transfer, worn friction plates, or a burnt-out factory clutch pack. The 18T drive gear is designed to match compatible manual clutch horizontal engines where the original clutch uses the same gear tooth count and dimensions.

Manufactured with a durable steel gear, reinforced clutch components, friction plates, and springs, this assembly is built for regular off-road use, trail riding, and small-displacement pit bike applications.
