JT SPROCKETS steel rear sprocket 50T, 428 pitch for KAWASAKI KLX 140, KLX 140 L, KX 100, KX 80, KX 85 1986-2027

JT SPROCKETS offers this rear sprocket for KAWASAKI KLX 140, KLX 140 L, KX 100, KX 80, KX 85 1986-2027. The rear sprocket receives the engine’s power through the chain and turns the rear wheel. Its number of teeth sets the gearing: with more teeth the bike accelerates harder but has a lower top speed; with fewer teeth it is the other way round.

Why fit a new rear sprocket?

The benefits:

• New teeth that hold the chain properly and make it last.
• The number of teeth is chosen to suit the terrain: more teeth for slow, tight sections, fewer for fast tracks.
• Aluminium or steel: aluminium is lighter, steel lasts much longer; “mud-release” models have cut-outs that clear the dirt.

When should you replace the rear sprocket on your KAWASAKI KX 85?

Pointed, hooked or uneven teeth, or a chain that lifts easily off the back of the sprocket: the chain kit needs replacing.
