Ignition cover

The ignition cover, or alternator cover, has a relatively simple job: it protects the ignition from moisture and the rider from rotating parts.

Ignition cover and performance

On 50cc motorcycles with AM6 or Derbi engine and scooters, internal rotor ignitions are often combined with an ignition cover with cutouts to prevent the ignition from overheating.

On motocross bikes, plastic ignition covers are often replaced with sturdier aluminum covers.

Note: Always remember to use a new ignition cover gasket.
