Description
Our new (2026 version) Roadster kits are designed to eliminate ignition and charging problems in one straightforward installation. Electrics connect directly to the standard Yamaha wiring loom* and require only basic set-up. The system retains the original AC lighting arrangement while natively upgrading the electrical system to 12-volt operation, giving noticeably brighter lighting. We stock kits with 12 volt horns, bulbs batteries etc.
The kit replaces the ageing ignition and charging components which, after nearly half a century, have often become a source of unreliability. This version now features an adjustable billet stator plate, precision-machined and accurately assembled to allow dialling in of timing.
Includes
-Fully assembled 12-volt billet stator
