2019 Honda CRF150R Expert overview

The 2019 Honda CRF150R Expert is a big-wheel junior motocross race bike for competition use. Its liquid-cooled, 150 cc four-stroke SOHC single has a carburetor, four valves, kick starting and a 5-speed transmission. The Expert trim pairs 19-inch front and 16-inch rear wheels with a longer swingarm, giving it a 34.1 in seat height for taller riders. Suspension consists of a 37 mm inverted Showa fork with 10.8 in of travel and a Pro-Link Showa rear shock with 11.1 in. Curb weight is 187 lb, fuel capacity is 1.14 gal, and the 2019 US MSRP was $5,399. This competition-only bike has a 150 lb rider weight limit.

Who it's for

This CRF150R Expert is for experienced junior riders competing in motocross, especially taller riders who need the big-wheel trim’s higher seat. Its 34.1 in seat and 187 lb curb weight are important fit considerations, and the 150 lb rider weight limit defines its intended rider range. It is a competition machine rather than a general trail bike, so it suits riders focused on race-track practice and events.
