2015 Honda CRF125F Big Wheel overview

The 2015 Honda CRF125F Big Wheel is the taller version of Honda's CRF125F trail bike: 19-inch front and 16-inch rear wheels (the standard CRF125F has 17 and 14), a 30.9-inch seat that is 2 inches higher, 10.4 inches of ground clearance and more suspension travel, 5.9 inches front and rear. Its air-cooled 125cc single has a 20 mm carburetor, an SOHC two-valve head, electric start with a kickstart backup and a four-speed gearbox with a manual clutch, and it stops with a 220 mm front disc brake. Mechanically, the 2015 model is the same as the 2014.

Who it's for

For beginners and younger riders who are ready for a clutch and gears but have outgrown the standard CRF125F: Honda calls the CRF125F an ideal bike for younger, beginning riders, and the Big Wheel's taller seat and bigger wheels fit taller riders. Honda's weight limit is 194 lb (88 kg), including the rider and any accessories. It is for off-road trail riding only, not the street.
