A low seat height, compact dimensions and kid-size levers and controls ensure that younger riders find the CRF70F easy to operate. But what makes this bike extra special is the three-speed semi-automatic transmission that does away with the need for a clutch lever. Your young rider gets to shift with his or her left foot just like on a bigger bike, but there's no clutch lever to worry about, so stalling is all but impossible. It's super easy to use, and extremely durable, too. The CRF70F also boasts a rugged four-stroke engine that requires no messy mixing of gas and oil and very little maintenance.
