Updates for the '07 YZ450F include new forged upper triple clamps as well as lighter rims and wave type brake rotors. There's also revisions to the clutch and an updated exhaust system. Factory equipment on the bike this year includes aluminium Pro Taper handlebars and a gripper style seat. There's also titanium footpegs as standard. The YZ250F has altered carburetion and ignition specs aimed at increasing bottom end and mid range power. The steering head geometry has been changed on the four stroke 250, it's been moved back by 3mm to help the bike turn quicker. The front brake caliper and master cylinder have also been updated this year to save weight. Both the 250 and 450 have a new oversized barrel clutch adjuster to make it easier to make adjustments on the fly. Again the 250F also gets the Pro Taper bars, gripper style seat and the titanium footpegs. |
