RFX offers this front sprocket for KTM SX 50, SX 50 JUNIOR ADVENTURE, SX 50 MINI ADVENTURE GS, SX 50 PRO SENIOR LC, SX 50 SENIOR ADVENTURE 2001-2008. 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 KTM SX 50?
