Specs At A Glance

Good To Know

Q: How do I know if my ignition coil has failed? A: Common signs include hard starting, misfires, rough idle, and a weak or absent spark at the plug. Testing primary and secondary resistance with a multimeter confirms whether the coil is out of spec.

Q: Can I replace just one coil? A: Yes, coils can be replaced individually, though many riders swap the full set at once for even spark output. Always disconnect the battery before starting the job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
