2013 Yamaha YZ250F Features and Benefits

Liquid-cooled, 250cc, DOHC, 5-valve (titanium), 4-stroke engine features a 13,500-rpm redline. This engine is super durable and a proven performer. It is one of the most reliable engines in its class.

•The 13.5:1 compression ratio provides fast, controlled combustion and excellent engine performance.

•Optimized 5-valve (3-intake & 2-exhaust) combustion chamber design provides the most efficient intake and exhaust flow for maximum power.

•Titanium valves decrease weight by more than 40% over a conventional steel valve train and reduce reciprocating mass (weight) for faster throttle response.

•”Load reduced” valve springs reduce the amount of force required to open the valves and thereby minimizes power losses associated with friction and improves torque in the low and mid ranges.

•Special chromium nitride coating on the tips of the intake valve stems reduces wear.

•Ceramic composite cylinder bore is a “liner less” design with the ceramic coating sprayed directly on the aluminum block to create the “sleeve” the piston travels in. The benefits include reduced weight (no heavy iron liner), reduced friction, extended cylinder life and excellent heat dissipation for consistent power delivery.

•Cylinder design features cutaways that allow the air trapped under the piston to enter a side chamber (or cutaway) to reduce horsepower-robbing “pumping losses.”

•Lightweight engine crankcases also utilize special cutaways to reduce “pumping losses.” The crankcase cutaways match the cutaways in the cylinder for maximum efficiency.

•Short skirt forged piston reduces weight and mechanical vibration, while offering excellent durability. The light weight design means fast throttle response.

•Engine counterbalance offsets the vibration produced by the crankshaft and influences the amount of engine vibration a rider feels, especially in the handlebar. Less vibration means less rider fatigue.

•Lightweight magnesium cylinder head cover.

•Dry sump lubrication system uses a remote oil tank reservoir positioned in front of the engine. This compact oil tank features a partition in the centre of the tank that improves the air-oil separation function. This tank is positioned low in the chassis which centralizes mass and lowers the centre of gravity for exceptional handling and a light feeling.

•Oil volume in the engine has been optimized to reduce weight and “oil drag” related power losses.

•5-speed transmission features “involute splines” on the transmission axles to ensure smooth shifting and instant hook-up under power.

•Multi-plate wet clutch provides an easy clutch lever pull.

•Lightweight, “quick-access” outer clutch cover provides fast, easy access for clutch maintenance.

•Compact automatic cam chain tensioner reduces maintenance and mechanical engine noise

•Keihin FCR-MX39 flat-slide carburetor with throttle position sensor (TPS) and an accelerator pump for excellent throttle response. The carb bore has been increased from 37mm (2011) to 39mm for improved engine performance and less intake airflow resistance. The diameter of the intake boot has also been increased to match the new carb.

•Air box design features a straight design “boot” between the air box and the carb for optimum air flow. The air filter holder / guide has been designed to reduce air flow resistance too.

•Washable, dual-stage, foam air filter.

•No fuss auto decompression system means fast, easy starting. The YZ250F restarts in any gear.

•Convenient, handlebar-mounted hot start lever ensures fast starts when the engine is hot.

•CD (capacitor discharge) ignition system delivers a strong, precise spark and monitors engine rpm to insure optimal timing for fast, strong response at all rpms.

•Direct ignition system means the ignition coil is integrated into spark plug cap to reduce weight and complexity.

•Compact, lightweight, single core, dual radiators provide outstanding cooling efficiency. The location of the rads has been optimized for maximum airflow and protection in the event of a crash, plus they help reduce the center of gravity and centralize mass too. Each rad has 10 cores.

•Lightweight titanium exhaust header pipe minimizes weight, improves performance and allows hassle-free replacement of the oil filter.

•The lightweight exhaust system utilizes a 4-stage expansion format that improves the cylinder filling induced by the exhaust pulse effect, resulting in excellent power characteristics.

•Lightweight aluminum muffler assembly features an internal diffuser pipe and noise reducing “punched hole pipe” to achieve maximum performance with reduced noise levels. The muffler can be repacked to maintain peak performance. The sound “deadening” material extends into the tapered end cone of the muffler for a further reduction in noise.

•Works-style race-spec “barrel adjuster” for on-the-fly clutch lever free play adjustments.



•Compact “Bilateral Beam” aluminum frame centralizes mass for exceptional handling and cornering. The frame consists of forged, extruded and panel aluminum parts. The top or main frame rails utilize 3 internal box sections for superior strength. The longitudinal and torsional rigidity balance of the frame has been optimized for precise cornering and a light, agile feel. The benefit is fast, easy cornering … one of the most important keys to winning races.

•The front and upper rear engine mounting brackets strengthen the engine’s function as a stressed member of the chassis.

•The head pipe (steering head), wheelbase, caster and trail dimensions are optimized to accentuate the engine and frame characteristics. The benefit is incredible turning ability and quick, yet stable handling.

•Removable rear sub frame is constructed of square-section, lightweight aluminum pipe. Its detachable design allows easy access when servicing rear suspension components.

•Lightweight, tapered aluminum swingarm is produced using “hydro forming”, a special method that uses high pressure water to form shapes. The swingarm design provides great overall “balance” with the frame for precise cornering, excellent traction and a light handling feel.

•Light yet strong cast aluminum upper and forged aluminum lower triple clamps. The new cast upper clamp features a 50% increase in rigidity for improved handling. Fork offset is 22mm.

•48mm, adjustable, inverted, Kayaba, “Speed Sensitive System” cartridge fork features a twin-chamber design, meaning the damper unit is in a separate structure which prevents aerated fork oil from entering the inner damper assembly and degrading its damping abilities. Since the inner damper is pressurized, it also prevents air bubbles forming in the oil.

•Front fork adjustments include: 20-way compression damping and 20-way rebound damping. Optional fork springs are available through Genuine Yamaha parts.

•The 48mm inverted KYB fork also features a Transfer Control Valve (TCV) system. The TCV enhances the damping force of the inner damper from mid stroke to full stroke and improves bottoming characteristics. The benefit of TCV is more precise control throughout the full stroke. The TCV is located on the upside of the spring and its function is controlled by piston speed, not piston position … hence the term “Speed Sensitive System fork”.

•Front wheel travel is 300mm or 11.8″

•Large “wrap-around” plastic fork protectors provide excellent lower fork tube protection. The “self-supporting” design reduces friction for smoother fork operation.

•Monocross link rear suspension system features a fully adjustable Kayaba, piggyback shock which features separate adjusters for high- and low-speed compression damping. Adjustments include: spring preload, 20-way rebound damping, 20-way low-speed compression damping and 2 turns of high speed compression damping.

•The shock uses a 16mm diameter piston rod. Kashima coating is used in the shock body and sub tank to reduce friction and improve suspension performance during a long moto. The Kayaba shock utilizes a full rebound oil lock system for excellent suspension function and great ride quality.

•Rear wheel travel is 317mm (12.5″).

•250mm floating front wave-style disc reduces weight and improves heat dissipation. It is squeezed by a compact Nissin twin piston caliper.

•245mm rear disc brake features a lightweight “wave-style” disc and a single piston Nissin caliper.

•Compact, lightweight rear master cylinder is an integrated design (fluid reservoir is integrated into the top of the master cylinder) for strong stopping power with excellent feel and control.

•Adjustable handlebar clamps offer a total of 4 different handlebar positions with an adjustment range of 30mm, to suit a wide variety of riders.

•Eye catching, compact body work enhances the lightweight feel and look of the YZ250F. This “minimal” bodywork is a flat design, allowing fast, easy rider movements. The ergonomics provide a natural and roomy riding position. The bodywork has been designed to maintain it good looks throughout the life of the machine.

•The lightweight, plastic resin 6.4 litre fuel tank compliments the chassis and its location helps to centralization mass. Its compact design allows excellent rider mobility.

•The seat surface texture has been designed to give a grip when needed, yet still allow easy rider movements. The seat cover resists clogging with dirt or mud to ensure long lasting good looks.

•Lightweight, 21″ front and 19″ rear Excel rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance and handling.

•Rear wheel assembly uses a large 25mm diameter axle and the rear hub features a second bearing on the sprocket side for increased rigidity and durability.

•Lightweight Sun Star rear sprocket.
