The exhaust system of the WR250X features Yamaha's EXUP System (Exhaust Ultimate Power Valve), which improves low- and mid-range torque without sacrificing power at higher revs. These unique features help the 249-cc engine produce 38.7 horsepower at 10,500 rpm, which makes it one of the most powerful in its class and almost on par with 300-cc and 400-cc single-cylinder engines. Power is distributed by a six-speed transmission with a second gear that was specifically revised for supermoto use. Also, engineers replaced the manual starter with an electric starting device.

A seriously capable chassis
The WR250X is based on an all-new, compact semi-double-cradle frame that incorporates three cast aluminum sections and a lightweight, tapered swingarm (also made of aluminum). Up front is a 46-mm inverted fork that offers 270 mm of wheel travel as well as an impressive 300-mm ground clearance.

A fade-free and ultra-high performance braking system is a must with any supermoto-type bike, which is why Yamaha equipped the WR250X with a 250-mm "wave-style" front disc and a 230-mm rear disc. Thanks to a unique design, 17-inch wheels, front and rear performance tires, supermoto-calibrated front and rear suspensions as well as large-diameter brake discs, this machine is definitely ready to face the competition. Actually, its only true competitor might be the Suzuki DR-Z400SM.

A performance-oriented dual-purpose bike
Finally, you should know that this motorcycle is also available in "R" trim, a dual-purpose variant perfectly adapted to these conditions. The WR250R is nearly identical to its more heralded sister, except for the 21-inch front wheels (17-inch in the back), off-road tires, less powerful yet easier-to-modulate braking system, specific transmission calibration as well as specific travel and settings for the suspensions. The WR250R is therefore better suited for energetic trail riding.

The only problem I see with these two magnificent beasts is that you can only choose one. So, do you prefer ultra-winding roads or the open trail? It's up to you.
