Key Features

Features Gallery
  • alt

    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.

  • alt

    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.

    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.

  • alt

    New graphics and duo-tone body colours

    With blue rims and duo-tone Icon Blue bodywork, the YZ250F looks as good as ever on the track and in the paddock. And to sharpen up the style the latest model comes with new in-mould graphics that remain looking good longer.

    Handlebar-mounted 2-mode mapping switch

    Once you’ve selected your two preferred engine maps and preloaded them for your riding session using the 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.

    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.

  • alt

    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.
