After releasing an all-new YZ450FX in 2019, Yamaha has completely overhauled the YZ250FX and added a new model to its cross-country motorcycle lineup for 2020 with the YZ125X. Meanwhile, the two other off-road competition bikes—the YZ450FX and YZ250X—receive graphic updates in 2020.

The YZ125X uses the same Yamaha Power Valve System (YPVS)-equipped 125cc, liquid-cooled, two-stroke, reed-valve-inducted engine as the YZ125. Where it differs from the motocross bike is the model-specific digital CDI ignition settings, power valve shape, and new cylinder head combustion chamber shape, all of which are focused on creating a broad power delivery that suits off-road terrain and a wide range of rider skill levels.

The YZ125X’s KYB Speed Sensitive System (SSS) fork and KYB shock are tuned specifically for cross-country riding. Off-road-specific components on the small-bore motorcycle include a sealed O-ring chain, kickstand, a reserve position on the fuel tank petcock, and Dunlop AT81 tires. The YZ125X will be available in June 2019 for $6,699.

The Yamaha YZ250FX is all-new for 2020 with many of the same updates the YZ250F motocrosser received in 2019. The completely revised engine features all of the changes the YZ250F received last year, but it has a six-speed transmission with updated gear ratios to make it more suitable for off-road riding. The engine can now be tuned wirelessly via the Power Tuner app—a wireless smartphone-based application that connects to the bike’s onboard CAN-bus network via a Communication Control Unit (CCU) by Wi-Fi. A handlebar-mounted map switch allows the rider to select between preloaded engine maps that are loaded and configured in the Power Tuner app. The valve cover of the engine is now blue as well.

The KYB SSS fork and KYB shock on the YZ250FX have revised settings for 2020, which are tuned specifically for cross-country racing. The bike also features Yamaha’s latest-generation aluminum bilateral beam frame and has more compact bodywork, a new 2.2-gallon fuel tank with a larger fuel cap opening, and different electronics. While the previous-generation YZ250FX came with Dunlop AT81 tires, the 2020 model is spec’d with Dunlop MX3S tires. The YZ250FX will be available in September 2019 for $8,499.
