Key Features

• For 2007, the bike that started the four-stroke revolution benefits from significant chassis and engine refinements that ensure the five-titanium-valved YZ450F remains at the head of the open-class pack.
• Modifications to the light and strong aluminum frame and suspension mean light, precise, confident handling at any speed.
• Five-speed gearbox provides maximum flexibility and the right gear for a wide range of riding environments.
• Ready to race straight out of the crate – with a ProTaper aluminum handlebar in adjustable clamps, titanium shock spring, ti footpegs, gripper seat, etc.

New for 2007

• Replacing the upper cast triple clamp with a light and strong forging, slightly reducing steering head rigidity, and the use of lighter outer fork tubes; lighter wheel rims and light wave-type brake rotors add up to super-accurate, super-responsive steering.
• Increasing the length of the rear shock by 1.5mm further sharpens handling. Replacing steel damping adjusters with aluminum ones removes even more weight from the four-way adjustable, titanium-sprung rear suspension unit.
• A more rigid clutch pressure plate helps put power to the ground and dissipates heat more efficiently, especially during partial-clutch operation. Shorter lever stroke with 12-percent reduced effort means instant response.
• New, titanium exhaust pipe fattens low- and mid-range power while simultaneously adhering to 2007 AMA noise regulations.
• This year's ProTaper aluminum handlebar bend raises the grips 8mm for an expanded cockpit. Forged bar clamps reduce weight for superior handling.

Engine

• 449cc five-valve DOHC liquid-cooled engine is super-powerful yet tractable.
• 39mm Keihin FCR flat-slide carb
