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.

Products by Prism Supply Co. in our web shop:

Prism Supply Battery Trays Antigravity 4-Cell

Custom battery carrier that holds the battery securely and safely in the frame. Specially made for 4-Cell Antigravity batteries. Laser cut from 3mm thick stainless steel plate, so it will probably last forever.

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.

A clean and and unobtrusive appearance are the decisive design features of this throttle grip by Prism Supply. The ingenious pulling mechanism consisting of a chain and carriage, allow for precise linear pulling actuation. Just a 90° twist will fully open your throttle (27 mm cable pull at the carb end). The clamp, polished to a high gloss, as well as the gas handle sleeve are made of aluminium. Suitable for all handlebars with 1" Ø and designed for all gas cables with snap ring (Ø 5/16”, 1996→). Throttle lock screw and grips must be ordered separately.
