2017 Honda CRF450R overview
The 2017 Honda CRF450R is a 450cc, liquid-cooled four-stroke motocross racer built for closed-course competition. Its single-cylinder SOHC engine has fuel injection, four valves and a 13.5:1 compression ratio; measured power is 57.5 hp on a dyno. A five-speed transmission, kickstarter and handlebar map switch complete the powertrain package. For 2017, the CRF450R received an all-new Unicam engine, a new sixth-generation twin-spar aluminum frame and a titanium fuel tank; Honda also added the CRF450RX enduro sibling. The bike has three selectable engine modes, a stock skid plate and adjustable Showa suspension with 12.01 inches of front travel and 12.36 inches at the rear. Seat height is 37.8 inches, curb weight is 243 lb, and fuel capacity is 1.66 gal.
Who it's for
This CRF450R is for experienced motocross riders and racers who ride sanctioned, closed-course tracks. Its 450cc four-stroke engine, kickstart-only setup and competition-focused suspension suit riders building speed through practice motos and racing, rather than beginners looking for an easygoing trail bike. It is not street legal in the United States, so it is not for riders who need a road-registered motorcycle.
