The 2019 YZ250F is fresh from the ground up. Not content with dominating the national race scene in Australia, the factory has specced the new YZ250F with an all-new engine, new frame, new bodywork and features never before seen in the 250cc class - such as smart phone tuning.
Smart phone tuning
Yamaha broke new ground with the YZ450F Power Tuner app by allowing convenience, flexibility and tunability via your iPhone or similar. Now the 250F can accept fuel and ignition timing changes instantly ‰ÛÒ _you can upload them to the bike via the onboard WiFi system for the ultimate in track-side tuning and engine diagnostics.
Electric starter system
Utilising a compact starter motor and ultra-lightweight lithium battery, the YZ250F brings the convenience of push-button starting to the racetrack, for effortless restarts under pressure, and relaxed riding when the clock isn't ticking. Powered by a high-capacity and ultra-lightweight, four-cell lithium-ion battery, the system adds minimal weight.
An engine offers YZ250F riders the best balance of high-rpm power with a board, useable powerband. The new, higher-compression piston and new intake and exhaust valving delivers outstanding engine character with a focus on top-end power delivery. For 2019, the cylinder is also lighter and angled more upright to improve mass-centralisation.
