JT SPROCKETS steel front sprocket 13T, 428 pitch for KTM SX 85, BETA EVO 80 2T SENIOR and HUSQVARNA TC 85 2004-2024

JT SPROCKETS offers this front sprocket for KTM SX 85, BETA EVO 80 2T SENIOR and HUSQVARNA TC 85 2004-2024. 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.
