Moturo 14-tooth sprocket for LIYA 49cc Mini Cross Dirt Bike

Moturo drive sprocket 14 teeth for LIYA 49cc Mini Cross Dirt Bike

The Moturo drive sprocket with 14 teeth for your LIYA 49cc Mini Cross, Dirt Bike or Pocket Bike — a classic wear part in the drivetrain. 4 mm chain pitch, 14 mm shaft mount, ready for installation.

The drive sprocket is located at the engine output and transfers power to the drive chain for the rear wheel. With 14 teeth, it acts as a reduction gear for 49cc two-stroke pocket bikes from LIYA. The 14 mm shaft mount fits common LIYA pocket bike engines, and the 4 mm chain pitch corresponds to the standard chain in this class.

Check for signs of wear before ordering: if the tooth flanks have worn down into a shark-fin shape or the chain skips, it is time for a replacement. It makes sense to replace the chain and, if necessary, the rear sprocket at the same time.

Replacement takes about half an hour with a socket wrench set and circlip pliers.

Frequently Asked Questions

Does the sprocket fit other 49cc pocket bikes?
If the shaft diameter (14 mm) and chain pitch (4 mm) match, yes. Compare with the existing part before ordering.

Is a circlip included in the delivery?
No. When replacing, it makes sense to install a fresh circlip at the same time.

When do I need to replace the sprocket?
When the tooth flanks wear down into a shark-fin shape or the chain skips. It is sensible to always replace it together with the chain.
