The rear sprocket is the large sprocket bolted to the rear wheel hub: together with the front sprocket and the chain, it transmits the engine's power to the wheel. Made of aluminium, it weighs much less than a steel sprocket, which cuts unsprung weight and makes the bike feel livelier.

Choosing the right number of teeth

For the same bike, go for the number of teeth of your current sprocket (it's often stamped on it). More teeth on the rear sprocket shortens the gearing: more acceleration, lower top speed. Fewer teeth lengthens it. Even one or two teeth make a clear difference; if you change a lot, the chain length may need adjusting.

When to replace it?

Teeth worn to a point or into a hook shape, worn down on one side only.
Chain that lifts away from the sprocket when you pull it rearwards.
Drivetrain noise, jerkiness or a chain that jumps under load.

Check the sprocket every time you service the chain. Always replace the rear sprocket, front sprocket and chain together: a new part running with worn ones wears out very quickly. Aluminium wears faster than steel, especially in sand and mud.

Fitting tips

Clean the hub and check that it isn't cracked or distorted.
Fit the sprocket the right way round (markings facing out) and tighten the bolts in a criss-cross pattern to the manufacturer's torque, with medium-strength threadlocker if the manual calls for it.
While you're at it, replace the front sprocket and the chain if they're worn.
Set the chain tension as per the manual, with the wheel aligned, then lube it with a suitable chain lube.
Recheck the bolt tightness and the chain tension after the first ride.

Why RENTHAL?

The Fatbar is made exclusively in the Renthal factory, from the brand's own 7010-T6 alloy: 28.6 mm at the clamps, 22.2 mm at the ends so you keep standard controls, and no crossbar. Its variable wall thickness saves weight and its shot-peened surface improves fatigue resistance, which counts when you're landing jump after jump.

Frequently asked questions

Aluminium or steel?
Aluminium is lighter and works well for motocross and racing. Steel lasts longer: it's the best choice for enduro, sandy terrain or if you put in a lot of hours.

Should the chain be replaced at the same time?
Yes, if it's worn: a stretched chain wears out a new sprocket in a few hours.
