If you are searching for a capable dirt bike you should take a closer look at the Honda CRF450X. Its tough character is combined with Honda’s famous reliability and you also get a capable 449cc, Unicam, liquid-cooled single-cylinder four-stroke engine paired with a five speed gear box.

For adequate performances, the Honda CRF450X is equipped with dual radiators which feature a refined core area for improved heat dissipation.

The bike rides on a pair of rugged wheels (18-inch rear and 21 inch front) which are combined with a set of capable suspension that help you deal with any type of terrain with ease. The front wheel is kept in check by a 47mm inverted Showa cartridge fork with 16-position rebound and 16-position compression-damping adjustability, while the rear one features a Pro-Link Showa single shock with adjustable spring-preload, 17-position rebound-damping adjustability, and compression-damping adjustment.

Taking its inspiration from Honda’s revolutionary 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. A Pro-Link® suspension, bulletproof 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.

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.

Not to mention about the lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height.

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.

The 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.

Brakes

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.

Superior Ergonomics

Placing the rider’s legs at the narrowest part of the frame improves comfort and handling, while the aluminum Renthal handlebar (971 bend) is rubber-mounted to help reduce rider fatigue and improve comfort. Out back there is a modern LED taillight integrated into rear fender. It’s light, compact, and bulletproof.

You also get an electric start system ensures trouble-free starting in all conditions. Electric starter drives the clutch side of the crankshaft to provide superior lubrication to starter gears while producing a narrow engine with a short, strong crank.
