Chain Guide Doppler Derbi / Aprilia / Gilera gold

Chain guide

The function of the chain guide is to prevent the chain from slipping. It is a wear part that you should check regularly and replace if necessary.
There are OEM quality chain guides to simply replace the original, but also tuning chain guides that ensure a longer life.

For old or rare motorcycles, you can also use a universal chain guide, which may need to be adjusted.

Please always remember to check not only the chain guide, but also the slider.
In general, you should always replace the entire chain kit, not just individual componenten, to extend its overall life:

• Front sprocket
• Rear sprocket
• Chain
