Key Features
 New optimized engine pumps out more power in the 8,000 to 12,000 rpm range with outstanding throttle response, thanks to new crankshaft webs, new vibration-reducing counterbalancer, new connecting rod, and low-friction piston rings, as well as a new piston, piston pin, and clip assembly that’s over 8% lighter overall than before. To take full advantage of these advancements, there’s also new CDI mapping and a bigger 39 mm carb with freer breathing air cleaner cage. Added to the new frame and suspension refinements, this latest engine gives YZ250F amazing balance – a powerful, light-handling machine with performance that’s accessible to all levels of riders.  
 The new-for-2012 Bilateral Beam frame has revised rigidity balance for superior cornering performance as well as great stability on rough, high-speed straights. Beefy new front suspension components plus revised rear shock internals and more rigidity in the swingarm axle block area give this new machine a serious handling advantage with light, quick steering.  
 The styling emphasizes the bike’s lightweight and nimble handling character. The sharp, horizontal lines set the bike apart with a clean, aggressive look.  
 New KYB® suspension is tuned to work with the also new Bilateral Beam frame for unmatched handling.  
 There’s no disputing the YZ250F’s unmatched four-stroke prowess – it was the 1st four-stroke 250 motocross bike on the market, the 1st to win an international race, the 1st to win an AMA® Supercross®, and the 1st to take an AMA® U.S. Supercross Championship® title, as well as the ?rst to win an AMA® National race.  
New for 2012
 Engine refinements, including a larger 39 mm carburetor, optimized CDI, and lighter piston with a lighter piston pin, mean YZ250F has more power as well as exceptional throttle response in the mid-to-high speed range.  
 The crankshaft web design is revised to match the lighter piston and reduce high-rpm vibration.  
 The air cleaner cage is a new design that provides increased airflow, contributing to the excellent throttle response in the mid-to-high speed range.  
 The new muffler is designed to meet 94 dB standards.  
 The new Bilateral Beam frame with a revised balance of longitudinal, lateral, and torsional rigidity is used for superior cornering performance, especially while exiting turns, as well as great stability on rough, high-speed straights.  
 YZ250F has beefy new outer fork tubes and triple clamps. The result? An increase in the front fork assembly’s torsional rigidity for unmatched chassis stability.  
 Fork offset has been changed from 25 mm to 22 mm to accommodate the new frame design. This shortened offset increases trail length which, in turn, contributes to excellent stability and reduces the inertial moment of the front fork assembly for quick, race-winning handling. The rider can take advantage of the higher level of performance throughout the turn.  
 The redesigned axle block portions of the swingarm provide greater rigidity to further optimize the rigidity balance between the new frame and the revised front fork assembly.  
 Front and rear suspension settings have been optimized for the new frame design, including a shock that uses a 16 mm shaft for optimal hydraulic flow, resulting in exceptionally smooth suspension and great traction capability.  
 New seat foam material has an excellent cushion feel.  
 Both color options feature rich-looking black rims and a gold-color drive chain.  
Engine
 The valve spring retainers are lightweight aluminum instead of steel, and light valve spring pressure reduces valve-opening force. Valve stem ends are chromium-nitride coated for exceptional reliability and reduced maintenance.  
 The exhaust port is "D" shaped instead of round. This increases velocity through the port for excellent throttle response, while enhancing the power feeling of the engine.  
 The low-mounted radiator is as far back as possible and the compact oil tank is positioned to achieve greater mass centralization.  
 The new 39 mm carburetor has a venturi-shaped bore, plus recalibrated jetting and an accelerator pump. This translates to impressive response when the rider snaps open the throttle, and contributes to superb mid-to-high-rpm power characteristics.  
 The intake boot offers a straight, smooth tract for excellent engine breathing and more power. The airbox is shaped to tuck neatly into the Bilateral Beam frame.  
 The exhaust pipe has been carefully tuned to optimize engine power, with a new muffler that meets 94 dB standards.  
Chassis / Suspension
 The new Bilateral Beam frame is crafted from a carefully chosen combination of forged and extruded aluminum pieces, all welded together to provide unmatched rigidity balance and superb cornering characteristics, as well as excellent handling on rough, high-speed straights.  
 The KYB® speed-sensitive front forks deliver exceptional damping feel, responsiveness, and bump absorption characteristics.  
 The 4-way-adjustable KYB® rear shock makes the most of the latest Bilateral Beam frame design. It’s low in the frame for excellent mass centralization, with a 16 mm shaft and new settings for optimal hydraulic flow.  
 The tank, seat, and rear fender are flat and the relationship between handlebars, pegs, and seat result in a natural, more forward riding position that facilitates rider movement. The fuel tank is placed toward the center of the bike for mass centralization. The ProTaper® bars are 4-way adjustable, and handlebar mounts and foot pegs optimize rider position on the chassis. Seat cushion material is updated for great rider comfort.  
Additional Features
 Riders have a choice of two color options: Team Yamaha Blue / White or White / Red.
