2004 Yamaha YZ250F, Dlr. Service just done. Tons of goodies , must see! - Not so many years ago they wouldve locked you up for suggesting a four-stroke single could spin to 13,500 rpm and produce a broad torque band the whole way there. It would have been unthinkable to conjecture that such a machine could win back-to-back AMA 125 Supercross Championships, not to mention a slew of magazine shootouts-including top honors in Dirt Rider, Motocross Action and Cycle World last year alone. The YZ250F did all those things right after kicking free of its crate; for 2004 its back and badder than ever . 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 accomodates 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 footpegs increase strength, reduce weight, and provide more grip. Internal engine mods reduce pumping losses for increased midrange. Exhaust flows through an all-new titanium header pipe for relentless power that just keeps building. Mere details. The important thing is that even with all its high-tech trickery and sharp competitive edge, the YZ250F is a blast to ride, even when youre only racing yourself.
