250CC LIQUID-COOLED DOHC 4-VALVE ENGINE

With its high efficiency front facing inlet, this hard-charging 250cc 4-stroke engine is one of the most technologically advanced designs in the class. Its formidable track record includes numerous MX race wins and titles – so you can be sure that the YZ250F Monster Energy Yamaha Racing Edition's reversed head engine has all the performance, useability and durability you need to win.

LIGHTWEIGHT ALUMINIUM 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 Monster Energy Yamaha Racing Edition'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, braking performance is as important as engine power. The YZ250F Monster Energy Yamaha Racing Edition'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 Monster Energy Yamaha Racing Edition 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.
