About the 2018 Yamaha WR250R

The engine on the WR250R has more of a streetwise temperament, with a linear power delivery that works well on any surface. Power generation comes courtesy of the 77 mm by 53.6 mm, 250 cc, water-cooled thumper that churns out 28 ponies and 17 pounds of grunt, but you have to wind it out to a screaming 10 grand to get all of it. Good news is; the engine likes to be wound up, so you can go ahead and wring the throttle with abandon. Part of this power comes from the Yamaha Fuel Injection (YFI) system and ECU-controlled, coil-on-plug ignition system.

The factory also uses something it calls the “EXUP Exhaust” valve and electronic intake-control valve to stretch the usable powerband a bit, and the results are encouraging. Between the engine performance, the six-speed tranny gearing and final-drive ratio, the WR250R can prowl around rocks and rough terrain with almost trials-bike control and resistance to stalling. The mill delivers its power while sipping at the gas at an impressive 71 mpg, and if you have the nerve for it, a top speed somewhere just shy of 90 mph. That’s on the superslab of course, not off-road.
