Honda CRF 300 torque specs

on

Got these from a friend and since the owners manual is pretty thin on these, I thought I might as well share these.

*** CAUTION: there may be typos eventhough I have double checked. If a value seems way off, DO NOT follow through. I don’t want you to break anything by overtightening. Comment below if anything seems weird or off. DO NOT trust your life with any infromation you found on the internet ***

    There is one thing other manufacturers should learn from KTM. Documentation. Although not free, KTM at least sells their service manuals on their website for a reasonable price.

    Thanks for this entry. When I had my 250rally I was really disappointed by the lack of available documentation on this bike.
