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
