.6 quarts. just barely over a half quart
.6 of a quart, same for the 50.
A Honda CRF-50 uses a 10w30 four stroke motorcycle oil. You should not use a truck or car oil in the CRF-50.
A CRF 50 is a four stroke, no premix on this bike.
10w40 oil if you are using a non-honda oil. We just switched our crf's (2 of them) to Amsoil and I can honestly say we felt a difference in the first 5 minutes!
0.6 US quarts.
10w30 four stroke motorcycle oil. do not use car or truck oil!
Regular unleaded is fine. It's a 4stroke so you don't need to add oil.
There was no 2002 Honda CRF 50. In that year, it was an XR 50, 4 stroke. In 2003, Honda introduced the 4 stroke CRF 150 and CRF 230. Next year, the XR 50 and XR 70 were relabeled as CRF's. The CRF is just marketing, cooler to be a CRF than the previous XR label for that same machine. (I'm a Dad whose kid went through an XR 50, XR 70, XR 100, and CRF 150, ALL 4 strokes.) The XRorCRF 50 is a 4 Stroke, 3 speed, automatic clutch.
CRF is just a label used by Honda in classifing the type of bike. for example Honda has lots of crf's. 50, 70, 80, 100, 150, 230, 250, 450.
