For the smaller teens the Honda CRF80F is a durable easy to shift manual transmission and has an 80cc four stroke engine. Rugged and easy to handle the 163 pounds and the 28.9 inches that make it easier to control at stops and tight corners. The drum brakes will allow you to stop when needed with room to maneuver.
