About the 2018 Honda CRF250RThe machine

The 2018 Honda CRF250R is a motocross competition bike powered by a fuel-injected, liquid-cooled DOHC single-cylinder four-stroke engine. Its five-speed transmission, aluminum perimeter frame, and fully adjustable Showa suspension are configured for closed-course racing. The front end uses a leading-axle inverted fork, while the rear uses a Pro-Link system with a single Showa shock. Stock equipment includes a titanium fuel tank, handlebar map switch, and skid plate. Honda built this CRF250R for sanctioned competition and experienced riders, rather than street use.

Who should ride it

This bike is for experienced motocross riders and racers who ride closed-course tracks and want a competition-focused 250cc four-stroke. Its adjustable suspension suits riders who set up their bike for track conditions, while the map switch and skid plate come ready on the stock machine. It is a fit for race practice and sanctioned motocross, not for someone seeking a street-legal motorcycle or a casual trail bike.
