2018 Yamaha YZ250FX

YZ250F championship-tech in a light, powerful machine built to win X-Country races.

• Innovative Hare Scramble/GNCC® Engine Design

Based on the championship-winning YZ250F , featuring Yamaha s revolutionary rearward slanted, liquid-cooled, DOHC 4-stroke power plant with forward-positioned straight downdraft symmetrical intake, and with an added sixth gear and wide ratio transmission, the YZ250FX is an out-of-the-box Hare Scrambles/GNCC® competition machine.

• High-Spec Engine

The engine is based on the 2017 YZ250F, and includes all the same race-winning features: an updated cylinder head, lightweight forged, two-ring, flat-top piston; a shorter, more durable piston pin with diamond like carbon (DLC) coating; a revised piston oil jet, and advanced connecting rod, crankshaft, and counterbalancer designs. Together, the result is improved peak power, power delivery and overall durability.

• 6-Speed Transmission

A wide-ratio 6-speed transmission is used to insure the right gear is available for the wide variety of terrain found in cross-country racing.

• Tuned Chassis

Nearly the same bilateral beam frame that is found on the championship winning YZ250F is used on the YZ250FX. The forged section at the swingarm pivot and engine mounting brackets help develop nimble lightweight feeling in the tight technical terrain while still providing stability in fast sections.

• Advanced Suspension

Industry-leading, fully adjustable KYB® spring-type fork with speed sensitive damping features revised valving for improved suspension feel and balance. The linkage type rear suspension features a KYB rear shock with settings optimized for cross country racing.

• Cross Country Features

With the electric starting system, a 2-gallon fuel tank, rugged plastic skid plate, 18-inch rear wheel and XC racing tires, the YZ250FX is ready to win right out of the box.
