Think of the CRF70F as the perfect stepping stone between its bigger siblings and the CRF50F. Your youngster a tad too big for the 50F, but not quite ready for the CRF80F or 100F? No worries. This bike features the same smooth three-speed semi-automatic transmission (no clutch to deal with) and novice-friendly four-stroke power as its little brother, only in a slightly bigger package. What could me more fun than that?
