How to Replace the Rear Sprocket on a GasGas EC 250?

Model: Gasgas Ec 250
Part: Checks and maintenance

Video tutorial

To replace the rear sprocket on the GasGas EC 250, loosen the bolt that secures the central spindle, which holds the rear wheel to the swingarm. Once this bolt is loosened, you can remove the spindle and take off the rear wheel.

Before doing this, detach the chain from the corresponding sprocket. This will allow you to unscrew all the bolts that secure the sprocket to the centre of the wheel so that it can be replaced with a new spare part.

After installing the new sprocket, reassemble everything.
