Description

WR250R – Engineered for the extreme.
Saturday and Sunday are your days. The days you live for. The WR250R is the ultimate weekender. Much more than just another trail bike, it’s a blend of Yamaha’s world-dominating off-road know-how and the no-compromise attitude of our R-Series supersport bikes.

It’s engineered to deliver the purest feel and feedback, so you’ve got the confidence to take your technique to the next level and ride like you’ve never ridden before.

Equipped with lightweight titanium inlet valves, the liquid-cooled, 4-stroke, DOHC, 4-valve, single-cylinder engine pushes hard all the way to 10,000 rpm, making this one of the strongest 250 singles ever built by Yamaha.
