TIP:
●Air filter
•This model’s air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with compressed air to avoid damaging it
•The air filter element needs to be replaced more frequent when riding in unusually wet or dusty areas

● Hydraulic brake service
• After disassembling the brake master cylinders and calipers, always change the fluid. Regularly check the brake and clutch fluid levels and fill the reservoirs as required
• Every two years replace the internal components of the brake master cylinders and calipers, and change the brake fluid
• Replace the brake hoses every four years or if cracked or damaged.

About the 2016-2018 Yamaha WR250F

The engine was on the receiving end of a pretty major overhaul for the 2018 model year. New heads sport new valve springs, revised ports and higher-lift cams for the light and strong titanium valves. The piston, con rod and wrist pin likewise saw an update to save weight. As cool as all that is, it’s the 3D-mapped engine control that steals the show here and Yammy thoughtfully programs that with an Enduro-optimized ignition and injection control curve.

A push-button starter replaces the old kicker for reliable starts and restarts, and an electric fan serves to force cooling air over the radiators to maintain heat control in spite of slow speeds. A 77 mm bore and 53.6 mm stroke gives the WR a 249 cc displacement with a 13.5-to-1 compression ratio and a 44 mm Keihin throttle body on induction control. The factory stuffed a six-speed gearset in the wide-ratio, constant-mesh transmixxer with a standard wet clutch and O-ring chain final drive.
