‘The Ignition Only Roadster’ – Our lowest priced DT360/400 B&C electronic ignition.

Fixes ignition faults once and for all!

Modern, re-designed ignition which fixes all the problems the standard ignition suffers. We have developed an ignition that requires minimum effort yet fixes the many problem these models suffers. Designed to accept the standard 6v lighting coil so we can offer you true performance up-grade that allows owner to swap the standard 6 volt lighting on to it, keeping the machine 6 volts.

The standard ignition suffers multiple problems, the pick-up is weak and the CDi unit design was quickly dropped and never used again. Rex’s conversion will fix all of these problems with the ignition – once and for all! 

As supplied this kit may be used ‘ignition only’ but if you want,  add the standard lighting coil and keep the bike’s original 6 volt lighting. This is a specific solution for these bikes which has proven extremely popular.  With years of development and a solid reputation for reliability this is a truly cost effective and simple solution.

Note the standard wiring loom with its original connectors is required.

Requires the flywheel to be stamped “FOTO2171 or FOTO2173”.
