With an outstanding track record that includes numerous MX2 Grand Prix race wins as well as a string of 250 Supercross titles in the USA, the YZ250F is born to win. And with its reduced unsprung weight and refined suspension performance, this high-tech motocross weapon is sharper, quicker and smoother – ready to own the podium.
A key feature of the YZ250F is the high-tech reversed head 250cc engine. Its unique front facing inlet forces fresh air into the fuel injector to give you holeshot-winning acceleration and instant power whenever you need it. And this compact engine layout contributes significantly towards the bike’s agile handling by centralising mass.
Fast, agile and smart, the tuneable YZ250F is built to deliver the ultimate performance at every track.
MX2-WINNING ENGINE DESIGN
With its high efficiency front facing inlet, this hard-charging engine is one of the most technologically advanced designs in the class. Its formidable track record includes numerous race wins and titles – so you can be sure that the YZ250F's reversed head engine has all the performance, useability and durability you need to win.
ALUMINIUM BILATERAL BEAM FRAME
The lightweight aluminium beam frame makes this one of the sharpest and most agile handling bikes in its class. By using frame walls of different thicknesses, Yamaha's designers have built-in different levels of rigidity in key areas in order to achieve a balanced and great handling chassis that gives you the feedback and confidence you need to perform at your best.
EASY-TO-USE POWER TUNER APP
Yamaha's invisible advantage is the free Power Tuner app that makes it easy to adjust engine performance character to suit different tracks, changing surface or weather conditions – via your smartphone.
HANDLEBAR-MOUNTED 2-MODE MAPPING SWITCH
Once you've selected your two preferred engine maps and preloaded them for your riding session using the Yamaha Power Tuner app you can select your mapping using the handlebar-mounted switch. This on-the-fly adjustment enables you to switch the mapping mode – with the throttle shut – while riding, giving you the ultimate control in all conditions.
ELECTRIC STARTER SYSTEM
The YZ250F gives racers the edge right out of the gate. Standard equipment includes electric start, lightweight lithium battery, advanced fuel injection, a front-positioned intake, and rear-positioned exhaust layout to deliver the widest spread of power with reliable performance while balancing the weight for excellent mass-centralisation.
IMPROVED SUSPENSION SETTINGS
The YZ250F's SSS (Speed Sensitive System) front forks are amongst the best in class, and feature new low speed damping settings for more responsive handling. New suspension settings are also used in the rear monocross system, to give improved traction and a better feel.
NEW LIGHTWEIGHT CHASSIS COMPONENTS
Various measures have been made to get unsprung weight as low as possible for even more responsive chassis performance. A new lightweight rear hub as well as a redesigned chain contribute towards the latest model's weight reduction.
LARGE-PISTON BRAKE CALIPER
When it comes to reducing lap times, the braking performance is as important as engine power. The YZ250F's 270mm front disc is gripped by a lightweight caliper with dual large diameter 25.4mm pistons that deliver class-leading performance together with plenty of feel.
WIDER REAR RIM AND TYRE
The YZ250F is fitted with a new wider 2.15 inch rear rim which is equipped with a wider 110/90-19 rear tyre that hooks up more effectively for increased traction and more holeshot-winning performance.
