JT SPROCKETS steel front sprocket 11T, 420 pitch for GILERA RCR 50, SMT 50, ZULU 50 and APRILIA MX 50, RX 50, SX 50 2001-2020

JT SPROCKETS offers this front sprocket for GILERA RCR 50, SMT 50, SMT 50 DRIFTING, ZULU 50 and APRILIA MX 50, RX 50, SX 50 2001-2020. 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.
