JT SPROCKETS steel rear sprocket 420 pitch for HONDA CR 80, MBX 80 FWD, MT 50 S, MTX 80 RF, MTX 80 RS 1980-1993

JT SPROCKETS offers this rear sprocket for HONDA CR 80, MBX 80 FWD, MT 50 S, MTX 80 RF, MTX 80 RS 1980-1993. 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 HONDA MT 50 S?

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

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.
