YAMAHA HAS introduced two radically revised off-road motorcycles and an all-new sport quad for 2010. All three units are scheduled to be in dealerships this month.
MSRP: $8,090 (White/Red)/$7,990 (Team Yamaha Blue/White)
Revisions made to the YZ450F for 2010 include a new rearward-slanted cylinder to aid optimum mass centralization and power output; new fuel injection system; a new Bilateral Beam frame; and revamped styling that includes updates to the front and rear fenders, intake cover, front fork protector, and number plate, along with the fuel tank and seat. Finally, an optional GYTR Power Tuner lets bike tuners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions.
MSRP: $7,090 (White/Red)/$6,990 (Team Yamaha Blue/White)
Updates to the YZ250F include a more compact Bilateral Beam frame specific to the 250; an optimized engine delivering more power in low-to-midrange; a newly designed exhaust system; recalibrations to the KYB suspension; a new clutch with a wider engagement range; and new styling.
Yamaha's 17 ATV models for 2010 are highlighted by the all-new YFZ450X, which replaces the original YFZ450 and joins the YFZ450R in the OEM's sport quad line. In fact, the 450X and 450R share the 5-valve DOHC liquid-cooled fuel-injected single cylinder 449cc engine. The main difference is, with a 46.1-inch-wide track, the 450X is designed specifically with the trail rider in mind.
