2004 Yamaha YZ 450F, An awesome deal on this solid MX machine.It's fast, it's furious, and it's Motocross Action magazine's 2003 Bike of the Year...
Keeping our ears to the dirt has been critically important over the years, and we've been picking up some seriously strong vibrations ever since we built the world's first modern four-stroke motocrosser. Making improvements is how we continue to evolve a tighter, quicker, easier-to-deploy package.
Upgrades for 2004 consist of a rigid 48mm fork with new settings for a smooth, compliant and progressive feel. New, titanium footpegs and gripper-style seat cover material improve the crucial interface between man and machine -- and man, what a machine: 222 pounds of high-tensile steel-framed, loam-launching, terrain-following, thrill-seeking motocross machine.
Yamaha-exclusive five titanium valve head (three intake, two exhaust) reduces reciprocating mass and helps make 11,000 rpm a regularly recurring event.
Bringing a 95mm piston to life against 12.5:1 compression can be hard work; YZ450F's genius auto-decompression system and hot start lever make it quite easy.
The YZ450F's high-revving counterbalanced 449cc liquid-cooled five-titanium valved 39mm Keihin-carbureted single is pure moto winning magic.
And four speeds are plenty, given the YZ450F's seismic spread of power -- and a heavy-duty clutch that gets the power to the ground consistently.

Video: Catalunya 2009, that pass
Mon, 19 Dec 2011The battle between Valentino Rossi and Jorge Lorenzo from Catalunya was one of the most memorable and thrilling races from recent years, a definite candidate for one of the Greatest Grand Prix races - ever. Passing Lorenzo at the final corner was the defining moment that is still talked about today, but for me the most incredible and bold pass made by Rossi in those final few laps was out-braking his former Yamaha team-mate around the outside into turn one.
