The 2008 Honda CRF150R is a motocross race bike with a carbureted, liquid-cooled 149 cc four-stroke single-cylinder engine. Honda’s Unicam four-valve layout pairs with a five-speed transmission and kick starting. Fully adjustable Showa suspension includes a 37 mm inverted cartridge fork with 10.8 in of front travel and a Pro-Link rear shock with 10.7 in of travel. The steel-frame CRF150R has a 32.8 in seat height, 11.9 in of ground clearance, a curb weight of 183 lb, and a 1.14 gal fuel capacity. Its 17-inch front and 14-inch rear wheels distinguish it from the CRF150R Expert’s larger-wheel setup. It is not street legal in the US.

Who it's for

This bike suits motocross racers and riders who spend their time practicing or competing on closed dirt tracks. Its fully adjustable Showa suspension gives racers adjustment for their weight and track conditions, while the 32.8 in seat height and 183 lb curb weight are useful fit considerations when choosing a race bike. It is not intended for street riding, and its motocross focus makes it a poor match for riders seeking a road-legal or general-purpose trail bike.
