2015 new Yamaha 2-stroke YZ125 & YZ250 features promotional video
2015 new Yamaha 2-stroke YZ125 & YZ250 features promotional video 2015 NEW YAMAHA 2-STROKE YZs Top Features: Modern, aggressive styling, including new front fender, front number plate, radiator shrouds, side number plates, air box, rear fender, fork guards, as well as some technical changes to the rear sprocket, rear brake disc protector, and rear brake caliper protector and wider foot pegs just like the 4 strokes. A light aluminum frame housing a patented YPVSTM Power valve-equipped ripper of an engine results in an awesome power-to-weight ratio. The YZ250 is ready to race out of the crate, complete with an aluminum handlebar, titanium foot pegs, gripper seat, and Excel® rims. Ultra lightweight means nimble handling with less fatigue. New for 2015: all-new modern, aggressive styling for 2015. The latest-generation KYB Speed-Sensitive fork, just lime the 4-stroke machines, has been added and provides industry-leading performance. A clutch lever position adjuster is adopted to allow adjustments based on rider preferences and accommodates differing hand sizes. The latest Dunolop MX52 tires are used for the best off-road traction, performance reliability. Engine: 249cc liquid-cooled reed-valve-inducted two-stroke engine is lightweight, compact, and features an incredibly wide, hard-hitting powerband. Patented YPVS power-valve system combines crisp, hard-hitting, bottom-end acceleration with strong midrange and eye-opening top-end. 38mm Keihin® PWK carburetor with power jet and throttle position sensor (TPS) provides precise fuel/air mixing and extra-crisp throttle response throughout the powerband. Special-design carbon fiber reed-valve petals improve throttle response and engine performance across the entire rpm range. Smooth-shifting, five-speed, close-ratio transmission with heavy-duty, multiplate clutch. Primary kickstarter ensures smooth, easy starting action and reduced weight. Large-capacity radiator features a ten-row core with four louvers for maximum cooling efficiency. Digital CDI ignition system delivers precise spark for faster, stronger response anywhere in the powerband. Trick, works-style clutch lever features race-spec barrel adjuster for on the fly adjustability. Chassis/Suspension: YZ250F-style front-brake caliper and wave-style front and rear discs minimize unsprung weight and provide excellent stopping power. The KYB® 48mm forks feature the Speed-Sensitive System that uses piston speed to control damping force for super-precise handling and a smooth ride. A carefully engineered, advanced aluminum frame and swingarm give the YZ250 the best handling in the 250 class. Removable aluminum rear subframe is constructed of square-section tubing for reduced weight. Rear, fully adjustable KYB® shock features a steel shock spring and reduced-friction Kashima coating of internals. 12.4 inches of travel, separate adjusters for high- and low-speed compression damping, and a full lock oil rebound system for increased comfort all add up to fantastic rear wheel control and a sweet ride. Lightweight 21-inch front and 19-inch rear Excel® rims provide exceptional durability and help reduce unsprung weight for optimal suspension, performance, and handling. Tapered rear wheel spacers ease sliding the rear wheel into place for quicker tire changes. Premium Dunlop® knobbies offer race-spec traction and wear. Additional Features: Wide-diameter fuel tank cap ensures easier usage, while larger tank opening means faster, hassle-free refueling. Special-design "gripper" type seat and fuel tank aluminum handlebars in an adjustable top clamp create greater freedom of movement and more comfortable ergonomics for riders. Wide, cleated, folding foot pegs are lightweight and provide excellent comfort, grip and ground clearance.

YFZ 450 Vs YZ 250 (2 stroke). Read description!
1994 YZ 250 Wins a drag race against a 2007 YFZ 450. Yfz 450 mods: hmf full Exhaust...header and silencer, airbox lid, and cotton K&n style filter. 180 lb rider. Yz 250 mods: boyesen reeds and cage, fmf fatty gold series pipe, fmf power core 2 silencer. 310 lb rider Both machines have stock bore, stroke, and engine internals, aside from a wiseco piston in the yz 250. In case it's difficult to see what happens because of the lack of zoom, the quad jumps a full length off of the line and from there on the bike pulls away hard (even with a rider over 100 lbs heavier). the bike let off at the end hundreds of feet from where the camera is because they were both topped out and the bike rider wanted to give the camera some sign language..If you listen to the sound of the bike, it let off LONG before it got to the camera..only then did the quad catch up and pass
