No, its a 4 stroke.
it is a 4 stroke so unleaded.
there really is no "proper age" for an xr 70. but, most xr 70's are riden by 10-13 year olds.

I've heard it's about 50 mph.
about 250mph on pavement with racing fuel/high octane mix. And don't forget to put tranny oil and jet fuel into the gear box. and where do you get jet fuel you may ask? I have hook-ups(steal it) at the airport.
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.
