Prism Supply Co.

Prism Motorcycles began by designing and manufacturing high-quality custom motorcycles and parts. Later they realized that there was a lack of quality made clothing and motorcycle accessories and expanded the company to encompass all things motorcycle/ outdoor related. To create something designed by the rider, for the rider. Something that matters. Something that sticks around for generations. Something made in the USA.

Prism Supply Quick Stick Starter Lever
Prism Supply Quick Stick Starter Lever
The part is mounted, instead of the solenoid cover, with three screws on the starter and complety replaces the electrical starter circuit. Moving the lever to the right (in the direction of travel!) causes the starter pinion to engage in the starter clutch and closes the contact for the starter motor. A spring on the lever prevents it from becoming loose. Fits Big Twins and Sportsters, but may need to be relocated or modified depending on exhaust system.
