The small toothed sprocket on the gearbox output shaft: it is what drives the chain.

Choose the number of teeth from the list.

AFAM offers this front sprocket for BETA RR 125, RR 125 4T MOTARD, RR 125 4T MOTARD LC, YAMAHA WR 125, WR 125 X, YZF 125, HM CRE 125 BAJA 4T, CRM 125 DERAPAGE 4T, CRM-F 125 X and RIEJU MARATHON 125, MARATHON 125 SM PRO, MARATHON PRO 125 SM 2008-2026. 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?

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

Choose the number of teeth from the list: fewer teeth on the front sprocket (or more on the rear) gives more acceleration, the opposite gives a longer gearing.

Cross-Mania tip: Replace the front sprocket together with the chain and rear sprocket, renew the sprocket nut or circlip and check the output shaft seal.
