YZ250F
Its new lightweight electric starter saves valuable seconds when it matters – and with Yamaha’s exclusive Power Tuner app and adjustable mapping, it’s easy to choose the exact power profile for optimum race results at every track.
The compact new chassis increases agility – and new suspension systems deliver winning performance with class-leading feel. So expect more. Because the all-new Yamaha YZ250F gives you the highest level of tuneable performance ever seen in the 250cc class.
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.
Yamahas 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.
Once youve 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.
