On the StealthStarter Kickdrive there's no built-in solenoid as on other Harley starter motors. In order for the high starting currents no to pass via the handlebar push-button, there's this here relay.

After extended market-research of the right part for our aims — which were not always completely non-destructive — we stayed with the one that we propose on this page. From a technical point of view this part is a true solenoid, the contact surface corresponding to an AGW 4 wire (~21 mm²). Since we equip the Cannonball StealthStarter with a slightlly smaller 16 mm² cable, you are absolutely on the safe side with this relay.
