You want a bike that can tackle the toughest enduro events, and come away with the big trophies. You want a bike that can handle a rugged trail during fun weekend rides with your friends, and come away with bragging rights. The bike you want is the Honda CRF450X. The CRF450X's liquid-cooled Unicam four-stroke engine is tuned to produce the muscular low-end and midrange power that will make short work of a tight, twisty uphill or a muddy corduroy section, plus the high-revving horsepower for when the trail straightens out. A light but strong twin-spar aluminum frame, Showa inverted cartridge fork, trail-smoothing Pro-Link rear suspension, and strong wheels with new black rims for 2011, provide the sure handling control that lets you put all that power to use. Big power and predictable handling — that's the Honda CRF450X formula. Track or trail, it's a winning combination.

S Powerful four-stroke 449 cc liquid-cooled four-valve Unicam engine is designed to produce power across a wide rpm band.
S Electric starter drives the clutch side of the crankshaft to provide superior lubrication of starter gears, and produce a narrow engine with a short, strong crankshaft.
S Lightweight, compact, internal auto decompressor system provides superb cold-starting and hot-starting operation.
S Unicam valve train provides the light weight of a compact single-cam design and the optimum combustion chamber shape for maximum power.
S Unicam valve train features a carburized single camshaft that directly actuates two 35 mm titanium intake valves. The camshaft exhaust lobe actuates two 30 mm steel exhaust valves via a forked, low-friction, roller rocker-arm.
S Lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height.
S Crankshaft is made of high-strength, low-carbon steel with carburized main journals for maximum durability at sustained high-rpm operation.
S Clutch cover and cylinder head cover are made of magnesium to reduce engine weight.
S Forged 12:1-compression slipper piston is lighter than a conventional design, revving quickly while maintaining excellent cylinder sealing and high-rpm power.
S Double-carburized connecting rod utilizes an updated big-end needle bearing and thrust washers for maximum high-rpm performance and durability.
S Nikasil cylinder lining is lightweight and provides cooler and quieter operation for extended engine life.
S Press-fitted aluminum spark plug pipe fits between forked exhaust rocker arms, further contributing to compact cylinder head design.
S 40 mm Keihin FCR-type carburetor features four rollers on the flat slide, resulting in very light throttle effort, smooth operation, crisp throttle response and excellent rideability.
S Carburetor features a throttle position sensor (TPS) and an accelerator pump that help maintain linear throttle response throughout the rpm range.
S The accelerator pump and drive system to provide better response to the throttle.
S 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.
