2012 Honda CRF150R overview

The 2012 Honda CRF150R is a junior motocross race bike with a 150 cc liquid-cooled, single-cylinder four-stroke engine, SOHC four-valve head, carburetor and five-speed transmission. It has a 32.8 in seat, 183 lb curb weight, 1.14 gal fuel capacity and kick starting. Suspension is a 37 mm inverted Showa fork with 10.8 in of travel and a Pro-Link Showa rear shock with 10.7 in.

For 2012, updates include a reshaped cylinder head and piston, a new cam profile, crankcase breather holes to reduce pumping losses, a direct-push accelerator pump on the Keihin carburetor, and low-friction bushings with revised suspension settings. It is designed for competition use by experienced junior riders and has a 150 lb rider weight limit.

Who it's for

This CRF150R is for experienced junior riders racing motocross who can manage a competition-focused four-stroke and its 32.8 in seat. Its 183 lb curb weight and kick-start system suit riders prepared for a purpose-built race bike, rather than someone looking for a casual trail machine. The specified 150 lb rider weight limit is an important fit constraint.
