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.
.6 of a quart, same for the 50.
It can go 65 to 70 mph
the Honda cr80r is a two stroke 80cc dirt bike, the crf 80 i don't believe there is such a thing but the crf 70 is a 70cc fourstroke dirt bike. the cr80r is a lot quicker bike
Depends on the model. CRF 80f will go about 40 mph, a CRF 100f will go 50-55 mph, a CRF 150F will go 60-70 mph, a CRF 250 will completley depend on the terrain and rider but the top speed is about 70 or more
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.
For a adult it goes from 40-48mph.For a kid it goes from 50-59mph.
it goes around 30-37 stock.
The best dirt bike for a would be a Honda CRF 100 for a male and a CRF 70 for a girl. Of course the real size of the bike depends on the size and experience of the rider.
