New for the 2004 Yamaha YZ450F:

• A bigger, 48mm fork with revised internals for a smooth, compliant feeling throughout the stroke, while a special new coating reduces stiction.
• New anodized triple clamps accommodates the larger forks and give that factory look while carrying the handlebar aggressively low and forward.
• Brake calipers now contain light, aluminum pistons.
• New, titanium foot pegs increase strength, reduce weight, and provide more grip.
• New gripper-style seat cover material.
