40 miles an hour
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
the top speed on a 230 is 70 because i raced it to my dads car with the speedomitor and i also have a cr85 expert and i raced that to my dads car and it went 78 and it does beet a 230 top speed
Stock, a CRF 150F will do around 60 mph while a CRF 150R will probably go a bit past 70 mph.
45+
The top speed of a crf230f is 70 m.p.s with stock sprockets , you have to open the throttle really wide in 6th gear to max out to this top speed.

A Honda top speed will in general top out at 70- 75 mph, depending on conditions and rider weight.

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.
