Servicing Your Honda; Before You Service Your Honda - Honda CRF450R Owner's Manual

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.
An ICM (Ignition Control Module) system is
