2017 Honda CRF450X for Sale

Innovations

• 18-INCH REARWHEEL: 18-inch rear wheel features same lightweight rear hub and HRC works-type lightweight-aluminum spoke nipples as used on CRF250R.
• LED TAILLIGHT: LED taillight integrated into rear fender. It’s light, compact and rigid.
• WORKS-STYLE REAL BRAKE: 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.
• SUPERIOR ERGONOMICS: Placing the rider’s legs at the narrowest part of the frame helps improve comfort and handling.
• 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.
• 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.
• 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.
• RENTHAL HANDLEBAR: Aluminum Renthal handlebar (971 bend) is rubber-mounted to help reduce rider fatigue and improve comfort.
• 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.
• HP SD: Perfected on the MX circuit, the Honda Progressive Steering Damper™ (HPSD™) not only improves cornering, but also helps reduce arm fatigue. The damping ratio varies according to handlebar-deflection speed and position, returning both improved stability and light, responsive handling.
• 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.
