By slanting the cylinder rearward and reversing the intake and exhaust ports, the YZ450F's mass is more centralized for amazing balance, unprecedented handling and cornering. The Bilateral Beam frame and suspension offer fantastic feedback to the rider. Add fuel injection to the mix of these innovations and you'll agree: backward is the right way forward. New for 2011: New clutch lever and pushrod for more consistent clutch feel during long motos.Key Features The 2010 YZ450F garnered the reputable title of Dirt Rider Magazine's “Bike of the Year.� Not to mention Cycle World's “Best Motocrosser� and Motorcycle Magazine's “Best Dirtbike of 2010.� YZ450F's rearward-slanted cylinder is a revolutionary advancement that achieves unmatched mass centralization, concentrating inertial mass toward the center of the machine. This bold design also swaps traditional intake and exhaust positions, putting the lightweight airbox and throttle body out front. This contributes to mass centralization for nimble handling while also achieving a straight intake tract for superb combustion efficiency that delivers more power. The cylinder is offset so the connecting rod is vertical at the moment of greatest combustion force, minimizing piston friction against the cylinder wall that could rob power. That means quicker response. The 4-titanium valve cylinder head is matched to a fuel injection system developed specifi cally for the YZ450F. Instantly adapts to changing air/fuel mixtures depending on altitude and temperature, for an engine that delivers no matter what conditions. The aluminum Bilateral Beam frame provides a superb rigidity balance that complements the engine for unmatched lightweight handling and cornering. The result? The best cornering, most nimble 450F for all track conditions. Revamped looks deliver new-generation styling, including front and rear fenders, intake cover, front fork protector, and number plate, along with the fuel tank and seat.* Price shown is net price after any factory to customer rebates and does not include applicable taxes, license, 100.00 doc fee, freight or setup charges.
