Magnetos

These self generating platform mounted units are suitable as a new installation or direct replacement for the original magneto on many motor-cycles. They have a built in electronic advance or can be supplied with fixed timing on request. (For more information on advance/retard versus fixed click here.)
We make a platform twin unit that can comfortably be run at engine speed for the Scott two-stroke twins.
Being able to run without a battery is even more important in competition where weight saving is especially significant. Our new magnetos also offer a weight saving over the original items. A twin plug option is also available on most units. Rev-counter advice.

Our flange mounted units are suitable as a new installation or direct replacement for the original magneto on many motor-cycles. They have a built in electronic advance or can be supplied with fixed timing on request. (For more information on advance/retard versus fixed click here.)
The flange mounted single is a popular choice for the Velocette and Vincent singles. Our current best seller is the Vincent flange mounted "V" twin magneto. The flange mounted parallel twin unit fits Ariel, BSA, Triumph, Norton, AJS, Matchless, Royal Enfield. Rev-counter advice.

We have produced magnetos for all sorts of engine configurations including the four cylinder Gilera racer built by Mark Kaye. We are pleased to discuss customers special requirements.

We are continually developing and testing our products. Besides the actual road testing conducted by ourselves we also run extended tests of our units on our workshop test bench. More>
