With cutting edge technology, WR250R boasts a performance envelope that shadows most competition enduro designs. Trust Yamaha to pull a new idea out of the box. The looks aren’t deceiving - Supertrail is an exciting new dimension in dual purpose design that tantalisingly blends the latest engineering developments with visual beauty and an outstanding riding experience whatever the terrain. Its 4-valve engine is the very first fuel-injected Yamaha on/off road engine, characterised by exceptional throttle response and power delivery that crescendos with a wailing 10,000rpm top end. Your very first ride will also reveal the taut, responsive handling, and make clear the depth of appeal to satisfy a wide range of riders.
250cc liquid-cooled, DOHC four-stroke 4-valve engine with fuel injection, adopting the same short stroke dimensions as the YZ250F and WR250F.
Smooth operating clutch combines with a six speed gearbox to provide slick shifting and a gear for every occasion.
Large diameter titanium intake valves and high lift cams with excellent follow and lift characteristics allow high rpm levels. Downdraft-type straight air intake layout combined with fuel injection and pent roof combustion chamber result in a quick ignition flame spread.
Fuel injection system also promotes excellent fuel economy and environmental friendliness. Sensors monitor crank, intake air pressure and throttle position.
