INNTECK Front Sprocket 13 Teeth for SUZUKI DRZ 400, RM 250 1986-2020

On SUZUKI DRZ 400, RM 250 from 1986 to 2020, the INNTECK 13 dents 432KC-13 front sprocket fits in place of the original part. Mounted on the gearbox output shaft (countershaft), the front sprocket passes the engine's torque on to the chain. Every tooth is loaded on every turn of the wheel: a worn front sprocket makes the chain jump and speeds up wear on the whole drivetrain.

Specifications

• Brand: INNTECK
• Manufacturer part number: 432KC-13

When to replace it?

• Teeth thinned, pointed or hooked.
• Chain that jumps or slaps under acceleration.
• Play between the sprocket and the shaft, or marked splines.

Check it every time you service the chain and replace it along with the rear sprocket and the chain. Many riders change the front sprocket with every new chain, because it wears much faster than the rear sprocket.

Fitting tips

1. Loosen the sprocket nut or bolt while holding the rear wheel with the brake, before slackening the chain.
2. Clean the countershaft and check the oil seal behind the sprocket.
3. Fit the sprocket the right way round, with a lock washer or threadlocker as on the original assembly, and tighten to the manufacturer's torque.
4. Set the chain tension and lube it with chain lube.
