• The compact, powerful 250cc four-stroke engine is developed from the class-dominating YZ250F, then tuned for enduro.
• Four-level Traction Control is selectable through the Power Tuner App to help maximize rear wheel traction.
• The WR250F features a compact, centrally-mounted electric starter system to minimize restart delays and add convenience.
• A redesigned aluminum bilateral beam frame is tuned to provide the perfect balance of stability and cornering performance.
• KYB® fork now includes a hand-adjustable knob for easy compression adjustments.
• A multi-function display features a speedometer, trip information, and convenient low fuel and engine warning indicators.

• Fast Fun

  Based on the race-winning YZ250F that features Yamaha’s revolutionary front-intake, rear-exhaust, liquid-cooled, DOHC 4-stroke power plant with an added sixth gear, wide ratio transmission and a range of enduro specific upgrades, the WR250F is super fast and fun.

  High Performance Four-Stroke Engine

  The compact, powerful WR250F engine includes all the same race-developed technologies of the race-winning YZ250F, tuned for cross country performance. Revised airflow system, new camchain and shorter muffler combine to increase linear power across the entire rev range.

  Precisely Tuned Chassis

  The highly developed aluminum bilateral beam frame features precisely tuned flex characteristics for competition-ready performance. The forged section at the swingarm pivot, and improved engine mounting brackets provide a nimble lightweight feeling in tight, technical terrain while still providing control in fast sections. Yamaha’s class-leading KYB® suspension has been revised to lower centre of gravity for a planted feel and increased abiliy in tight turns.

  High-Spec Braking Components

  The high performance braking system provides exceptional stopping power and control through high-spec componentry, including a rigid front caliper with larger diameter pistons, aggressive brake pad compound and a 270mm front rotor. The rear brake gets a lightweight rear caliper and hanger with a 240mm rear rotor to reduce unsprung weight.

  Sharp, Durable Graphics Scheme

  Sharp competition-inspired graphics scheme highlights the YZ’s unmatched racing pedigree. Premium Yamaha graphics are embedded to provide excellent durability and scratch resistance. Dark radiator louvres add to the aggressive look.

  Enduro Competition Features

  With a new electric starting system, rugged plastic skid plate, and 18-inch rear wheel, the WR250F is ready for fast fun.
