2016 Honda CRF 450X, King Of Its Class. Taking its inspiration from Honda s CRF450R motocross machine, the CRF450X gets Honda s magical touches that transform it into the king of the trail. Touches like the Honda Progressive Steering Damper, which helps reduce rider fatigue and improve cornering; an electric starter for easy start-ups in even the worst conditions; Pro-Link suspension; Unicam® engine; and the kind of durability Honda is known for. The Power to Win: Utilizing a Unicam® cylinder head, the CRF450X s 449cc liquid-cooled four stroke puts out maximum power over a wide rpm band. Easy Starts: Our push-button electric starter offers all-around convenience, whether you re starting out on your ride or quickly restarting in tough conditions. Control Freak: Perfected on the MX circuit, the Honda Progressive Steering Damper not only improves cornering, but also helps reduce arm fatigue.Innovations449cc Unicam® Engine: Honda s Unicam cylinder heads combine the best of single- and double-overhead-cam designs. The configuration contributes to a compact engine that saves weight over a comparable dual-overhead-camshaft motor and also permits a narrow included valve angle. This flattens the combustion chamber to facilitate ignition flame propagation, allowing a high compression ratio. Since less space is taken up in the cylinder head, the camshaft sits lower in the head for a more compact engine and a lower center of gravity.Twin-Sump Lubrication: Twin-sump lubrication system separates the oil supply for the crankshaft, and the piston and valve train from the clutch and transmission. This ensures a cool supply of oil to the clutch, eliminates clutch and transmission material contamination of the engine oil, reduces the amount of circulating oil and permits the use of a smaller oil pump.Gear-Driven Counterbalancer: Gear-Driven Counterbalancer reduces vibration and drives the water pump. Eight clutch plates provide the surface area necessary to handle the engine's massive torque, while carefully matched clutch springs provide a light feel at the lever.Titanium Intake Valves: Lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height.Dual Radiators: Dual radiators feature a refined core area for improved heat dissipation compared with conventional dual-radiator designs. Coolant recovery tank is located in front of the engine between the frame downtubes for improved center of gravity. Coolant tank is protected by a plastic skid plate.Works-Style Front Brake: Compact twin-piston front brake caliper, anodized-aluminum brake pistons and lightweight 240mm front disc offer great stopping power while minimizing unsprung weight for improved turning and handling.Works-Style Rear Brake: HRC works-type rear brake system uses a 240mm brake rotor to its integrated rear master-cylinder and fluid reservoir, a set-up t
It's a dream everyone had, but nobody could deliver on—until Honda invented the CRF450X. The light weight and power of a motocross bike, available to trail riders, Baja demons, and cross-country racers everywhere. But actually the CRF450X is a whole lot better than just an MX bike off the track. It gets a ton of specialized touches and refinements that hone it for the trail.
