Rex’s Speed Shop HT Ignition Coil – Yamaha SR400, SR500 & TT600
Our replacement HT ignition coil is designed specifically for the Yamaha SR400, SR500 and TT600 CDI ignition systems.
Unlike a generic replacements, this unit has a metal frame that wraps around the coil body. This forms part of the magnetic circuit, helping to concentrate the magnetic field and transfer energy efficiently to the spark plug.
With 70 mm mounting centres* and a plug-in electrical connector, it is designed as a straightforward replacement for the original Yamaha coil.
