2024 Honda CRF150R Big Wheel overview

The 2024 Honda CRF150R Big Wheel is a competition motocross bike for experienced junior riders. Its 150 cc, liquid-cooled, four-stroke single has SOHC, four-valve architecture, carburetor fuel delivery, a kick starter and a five-speed transmission. The Big Wheel trim uses a 19-inch front wheel, a 16-inch rear wheel and a longer swingarm, giving it a 34.1 in seat height for taller riders. A 37 mm inverted Showa fork provides 10.8 in of front travel, while the Pro-Link Showa rear shock has 11.1 in of travel. Curb weight is 187 lb, and fuel capacity is 1.14 gal. It is designed for competition use, has a 150 lb rider weight limit and is not street legal in the US.

Who it's for

This bike is for experienced junior riders racing motocross who need the Big Wheel’s taller fit. Its 34.1 in seat, 19-inch front wheel and 16-inch rear wheel suit taller riders better than the smaller-wheel CRF150R. The 187 lb curb weight, kick start and competition-only design make it a race bike for riders prepared to manage a purpose-built motocross machine, not a beginner trail bike. The rider weight limit is 150 lb.
