A brand new aftermarket external ignition coil supplied under RMSTATOR part number RM06162, covering the Honda TRX 420 and TRX 500 quads and the Kawasaki KVF 750 Brute Force from 2008 onwards. The ignition coil converts the low voltage pulse from the ignition system into the very high voltage that fires the spark plug, so a coil with breaking down insulation produces a weak or intermittent spark long before it fails completely.
Before fitting, note that you must re-install your own OEM spark plug cap onto this coil. With the original cap transferred across the part becomes a plug-and-play unit, a direct fit that is easy to install. The coil is wound to a nominal 2.6 ohms, carries a 240 mm lead, and its mounting holes are set 65 mm apart to match the original bracket. It carries an unusually broad cross reference list covering both Honda and Kawasaki part numbers, so check the number on your existing coil against the table below. Every unit is bench tested before it leaves the factory.

Frequently Asked Questions
Will this fit without modification?
Yes, provided you re-install your OEM spark plug cap onto the new coil. The mounting holes are 65 mm apart to match the original bracket, so no drilling or bracket changes are needed. Given the breadth of the cross reference list, always confirm the number stamped on your existing coil against the table above.
What is included?
One external ignition coil, tested before dispatch. No spark plug cap is supplied, so retain your original cap and transfer it across when you fit the new coil.
How do I know my old ignition coil has failed?
Measure the primary resistance across the coil terminals. This unit is wound to a nominal 2.6 ohms, so an open circuit or a reading far from that figure points to a failed coil. On the machine, look for a weak or intermittent spark, hard starting, a misfire that worsens as the engine heats up, and stalling under load.
Why does one coil cover both Honda and Kawasaki machines?
Both manufacturers used a coil of the same electrical specification and mounting pattern across these model ranges, which is why RMSTATOR publish a single cross reference list containing both Honda 305xx series and Kawasaki 21121 series numbers for this part.
