Just how good is the CRF®450X? Here’s a hint: it's won more races in Baja than all other recent 450-class machines combined.
But this bike is merely a sum of its parts – intelligently-engineered parts taken from its MX-winning cousin and specially tuned for the trail. Like the Honda® Progressive Steering Damper that helps reduce rider fatigue and improve cornering. An electric starter for easy start-ups in even the worst conditions. A Pro-Link® suspension, bulletproof Unicam® engine and the kind of durability Honda® is known for.
Put it all together and you’ve got perhaps the best off-roader ever built.
Baja has a reputation for being ruthless. Only the best bikes can conquer the elements, and one bike has conquered all the others every time: the CRF®450X.
Utilizing a Unicam® cylinder head, the 449cc liquid-cooled four stroke in the CRF®450X puts out maximum power over a wide rpm band.
Perfected on the MX circuit, the Honda® Progressive Steering Damper not only improves cornering, but also helps reduce arm fatigue.
Compact twin-piston front brake caliper, anodized-aluminum brake pistons and lightweight 240mm front disc increases stopping power while minimizing unsprung weight for improved turning and handling. HRC® works-type rear brake system adds a 240mm brake rotor to its integrated rear master-cylinder and fluid reservoir, a set-up that eliminates the separate reservoir and hose.
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 skidplate.
Lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height.
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 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 lower center of gravity.
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.
Twin-sump lubrication system separates the oil supply for the crankshaft, 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.
