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.
about 60-65
54
.6 liters
2.5 oz +/- 0.03
The carburetor is a 22 mm one.
if its a xr you shouldent have to mix the gas
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.
Oh, dude, the Honda XR 70 has about 4.5 horsepower. It's not exactly a speed demon, but hey, it'll get you where you need to go... eventually. So, if you're looking to race, maybe stick to Mario Kart instead.
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.
