Moturo reinforced sprocket 14 teeth 420 for ATV Pocket Quad

Moturo reinforced drive sprocket, 14 teeth, 420 chain for ATV, pocket quad, and dirt bike

The Moturo 14-tooth drive sprocket for 420 chains — the reinforced version for your ATV, pocket quad, or dirt bike, serving as the typical wear counterpart to the chain. 6 mm material thickness, ready for installation.

The drive sprocket is located on the transmission output shaft and transmits the engine torque to the chain. 14 teeth for 420 chain pitch, 6 mm material thickness according to manufacturer specifications. The reinforced design withstands higher torque peaks than the standard sprocket.

When changing the drive kit, it is recommended to replace the sprocket, chainring, and chain at the same time, as uneven wear leads to increased stretching of the new chain.

Replacement takes about half an hour using a socket wrench for the mounting nut, a tool for the locking washer, and a torque wrench.
