Servicing Your Honda
Keeping your CRF well maintained is absolutely
essential to your safety. It’s also a good way to
protect your investment, get maximum
performance, avoid breakdowns, and have more
fun.
To help keep your CRF in good shape, this
section includes a Maintenance Schedule for
required servicing and step-by-step instructions
for specific maintenance tasks. You’ll also find
important safety precautions, information on oils,
and tips for keeping your Honda looking good.
The ICM (Ignition Control Module) system is
used on this motorcycle; consequently, routine
ignition timing adjustment is unnecessary. If you
want to check the ignition timing, refer to the
Honda Service Manual (page 166).
