DT360 | DT400 B & C Electronic Ignition Only Kit


In stock


Lowest priced option to fix this model’s ignition faults once and for all!

Brand new, affordable up-grade that replaces the standard DT360A, DT, IT, MX & YZ 400 generator. Our new billet stator with precision location ensures perfect ignition timing, so there is no need to carry out any ignition timing set up  – fit and go. It has been designed to run as supplied with no lighting coil fitted. However on models where a single 6 volt light coil was used, a skilled mechanic can swap out the old parts on to our stator to retain the 6 volt charging system.

This kit is great solution to replace the ageing and problematic OEM ignition.  You can fit this kit with confidence that there are no tricky adjustments. Rex has developed this system over many years, refining it to a standard few can match. The modern UK deigned and manufactured ignition brings reliability and up-graded performance compared to the OEM system.

The generator is the heart of your bike’s electrical system and we believe the RMK-8  ‘ignition only’ option is an unbeatable choice in terms of performance, compatibility and reliability. We develop and manufacture our own ignitions here in the UK so we can bring you performance that betters the original Yamaha equipment at an affordable price.

We’ve taken the time to check our parts fit and work correctly with the bike’s electrical system, you won’t even need a timing light! The CDi unit fits the OEM carrier.

Requires the flywheel to be stamped “FOTO2171, FOTO2172 or FOTO2173”.
