Motorcycle Electrical Parts, Batteries & Fuel Tuners

Batteries, starters, stators, regulator/rectifiers, ignition coils and modules, plug wires, switches, wiring, and fuel-management tuners. Electrical gremlins are diagnosis problems more than parts problems — a bike that keeps killing batteries usually has a charging-system fault, so test stator output and charging voltage before buying the third battery.

AGM and lithium batteries both beat old flooded types, but lithium wants a lithium-specific charger. Fuel tuners matter whenever intake or exhaust changes move fueling outside the stock map — emissions-related tuning products carry the same CARB restrictions we flag on exhausts. Dielectric grease on connectors is the cheapest reliability mod on this page.
