2009 Honda CRF70F
Introduction
A low-maintenance 72cc air-cooled single-cylinder
four-stroke engine and easy-shifting 3-speed semi-automatic
transmission make the exciting CRF70F a great introduction
to off-road motorcycling. Control is sharp and confident
with an easy-handling front fork and Monoshock rear
suspension. Downsized grips and a low seat ensure

graphics leave no doubt that this mini-champion is
on its way to a higher league.
