Monster Energy® Yamaha Racing Edition
Inspired by the YZ250F raced by the Yamaha Supercross team, the Monster Energy® Yamaha Racing Edition features an aggressive color and graphics package that stands out from the crowd.
All-New Cylinder Head
The YZ250F’s already potent motor was treated to a host of refinements, including an all-new cylinder head with an improved intake port shape, new exhaust camshaft profile, a new silencer, and an updated ECU and more—to produce stronger mid- to top-end power and increased peak power, while retaining its class-leading low-end torque.
New air box lid intake ducts have been added for increased air flow with a new high flow air filter, air cleaner boot featuring a new shape for increased flow and a larger diameter throttle body joint.
High Tech 250cc Four-Stroke
The YZ250F™ is ready to roost the competition with race-winning features never before seen in the 250cc class.
Power Tuner App
Yamaha’s free of charge and industry-exclusive Power Tuner app puts the flexibility and precision tunability of the GYTR® Power Tuner into your smartphone. Make fueling and ignition timing changes instantly and upload them to the bike for ultimate track-side tuning.
Electric Starter System
Utilizing a compact starter motor and ultra-lightweight lithium battery, the YZ250F brings the convenience of push-button starting to the racetrack for effortless restarts under pressure and relaxed riding when the clock isn’t ticking.
Advanced Engine Design
Featuring a high-spec piston, aggressive cam profiles, cylinder geometry and more, Yamaha’s reversed cylinder head layout works to give YZ250F riders the best balance of high-rpm power with a broad, useable powerband.
Tuned Aluminum Frame
Yamaha’s bilateral beam frame features main spars, engine mounts and mounting position which are designed to centralize mass and provide an ideal balance between cornering feel and straight-line rigidity.
Yamaha’s spring-type forks with refined, speed-sensitive damping give industry-leading suspension performance straight out of the box.
The crank case, cam chain and tensioner, waterpump, clutch basket, and the third, fourth and fifth transmission gears have all been refined to enhance overall durability.
