Specs At A Glance

Good To Know

Q: How do I know my ignition coil needs replacing? A: Common signs include hard starting, misfires, rough idle, and a noticeable drop in power under acceleration. Testing the coil with a multimeter against the service spec confirms whether it has failed.

Q: Do I need to replace all coils at once? A: Not always, but if one coil on an engine has failed, the others may be nearing the end of their service life. Many riders replace them as a set for consistent spark across all cylinders.

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