PBR steel front sprocket 520 pitch for HUSQVARNA CR 250, WR 250, WR 360, WRK 240, CAGIVA WMX 250 and KAWASAKI KX 250, KX 500

PBR offers this front sprocket for HUSQVARNA CR 250, CR 360, WR 250, WR 360, WRK 240, CAGIVA WMX 250 and KAWASAKI KX 250, KX 500 1983-1999. 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.

Specifications and fitting tips

• Chain pitch: 520
• Material: Steel
• Front sprocket version: Standard
• High quality steel alloy 18NCD5
• High wear resistance

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.
