AFAM steel front sprocket 420 pitch for HONDA CR 80, CRF 110, MONKEY, MSX 125, MTX 80 RF 1982-2027

AFAM offers this front sprocket for HONDA CR 80, CRF 110, MONKEY, MSX 125, MTX 80 RF 1982-2027. The front sprocket sits on the gearbox output shaft and passes the engine’s power to the chain, which turns the rear sprocket and the rear wheel.

Why replace the front sprocket?

The benefits:

• An inexpensive part that protects a new chain and rear sprocket.
• Made of steel to withstand much heavier wear than the rear sprocket.
• Changing the number of teeth is the simplest, cheapest way to alter the gearing.

When should you replace the front sprocket on your HONDA CRF 110?

Dished or hooked teeth: replace it straight away, otherwise it will ruin a new chain within hours.
