The amount of mileage you get out of a clutch will depend on multiple factors such as rider weight, terrain and driving style. In this guide we explain the common signs that your clutch is worn out and help you check the clutch for wear and damage.

Increase the life of your clutch

All 50cc mini motos have a maximum rider weight. Exceeding this maximum weight will cause the clutch too experience excessive ware and lead too the clutch pads wearing down too the metal and can also lead too the springs in the clutch breaking.

Another common cause of clutch wear is excessive revving of a mini moto. Whilst revving your mini moto when stationary might sound really cool. It will lead too clutch wear as the pads on the clutch will be slipping. It is recommended that when riding a mini moto the bike is brought up too speed and not revved whilst stationary. This will help increase the lifetime of your clutch.

Bolts to remove gearbox

The clutch on a mini moto 50cc sits behind the gearbox and so you will need to remove the gearbox to gain access to the clutch. The four bolts circled above will need removing so that the gearbox can be detached from the engine. All four of the bolts will need a 8mm spanner or sprocket to remove them. 

3) Slide the gearbox out of the way

Carefully slide the gearbox so that the clutch is clearly in view. If care is taken then the chain will not become detached from the gearbox meaning it does not need to be reattached. If the chain does come off you need to make sure it is reattached before reassembling the bike.

4) Assess the state of the clutch

Above is a photo of a clutch that is brand new. If the springs on your clutch have become detached or the pads have worn down to the metal then its time for a new clutch.
