The multi-championship-winning YZ250F dominates on the race track, at the shootouts and basically everywhere it goes. And with the Monster Energy Yamaha Racing Edition, privateers can have that factory look whether on the practice track or the starting gate.
ADVANCED 250CC FOUR-STROKE ENGINEThe YZ250F's liquid-cooled, DOHC 4-valve, fuel-injected powerplant features a forward-positioned straight downdraft intake with symmetrical intake/exhaust ports, high-spec piston, aggressive cam profiles and reversed cylinder head layout. The advanced four-stroke engine is known for its broad, useable powerband and class-leading low-end and mid-range torque.
Featuring a distinct rearward-slanted cylinder design, the YZ450F’s light, compact engine is ideally positioned within the frame for optimized weight distribution. Internally, steep valve angles allow for an even straighter down-draft intake port. More aggressive cam profiles and larger diameter exhaust header joint work together with a higher compression bridge-box-design piston, DLC-coated piston pin and longer connecting rod to churn out a broad, usable powerband, all thoughtfully packaged to provide an exceptional level of chassis balance and control.
INNOVATIVE POWER TUNER APP
The free-of-charge Yamaha Power Tuner app brings the power of the GYTR® Power Tuner to your iOS® or Android® device. Using wireless connectivity to talk to the bike’s onboard CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.
ADVANCED BILATERAL ALUMINUM FRAME
