With its slim ergonomics, easy start and agile handling, the Honda CRF 450X is ready to conquer the world of trail bikes.

Based on the CRF 450R Motocross model, the CRF 450X is powered by a liquid-cooled, single-cylinder, four-stroke engine with a displacement of 449 cc. The engine is mated on a wide-ratio five-speed transmission and is linked to a 1.9 gallons fuel tank(including 0.4-gallon reserve).

The stopping power is handled by a single 240 mm disc with twin-piston caliper up front and a rear single 240 mm disc.

To be able to conquer the toughest terrains with poise, the bike needed a pair of potent tires. Therefore it comes with a set of grippy tires that measure 80/100-21 up front and 110/100-18 at the rear.

The Honda CRF 450X is offered with a base price of $8,440

Dominate in the Dirt.
Along with its powerful and lightweight engine, the CRF450X has dozens of smart features like works-type front and rear brake discs, a narrow fuel tank that’s easy to move around, and an 18-inch rear wheel for superior tire selection and traction. In short, all the attention to detail you’d expect in a Honda.

Works-Style Front Brakes
Compact twin-piston front brake caliper, anodized-aluminum brake pistons and lightweight 240mm front disc offers great stopping power while minimizing unsprung weight for improved turning and handling.

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

Renthal Handlebar
Aluminum Renthal handlebar (971 bend) is rubber-mounted to help reduce rider fatigue and improve comfort.

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 skidplate.

Titanium Intake Valves
Lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height.

449cc 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.

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.

Twin-Sump Lubrication
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.

Superior Ergonomics
Placing the rider’s legs at the narrowest part of the frame improves comfort and handling.

Works-Style Rear Brakes
HRC works-type rear brake system uses a 240mm brake rotor to its integrated rear master-cylinder and fluid reservoir, a set-up that eliminates the separate reservoir and hose.

LED Taillight
LED taillight integrated into rear fender. It’s light, compact, and bulletproof.

18-Inch Rear Wheel
18-inch rear wheel features same lightweight rear hub and HRC works-type lightweight-aluminum spoke nipples as used on CRF250R.
