Yamaha recently introduced two wild new off-road models—the trail-capable WR250X and the closed-course, GNCC-targeted YZ250FX—both of which are based upon the current YZ250F motocross bike. The YZ250FX features electric starting, an 18" rear wheel, skid plate mounting tabs, a 6-speed transmission and a kickstand, while the EPA/ green sticker legal WR250F gets all of these features plus a cooling fan, headlight, enduro computer, and ECU/ muffler revisions, among other things. Although these two new machines have different purposes, they feature a lot of similarities that are in line with the high-performance of the MX variant—usable power, superb suspension, and great handling among them. In this video, DR Editor Chris Denison provides a first glimpse at these two machines in action from the US press launch at Cahuilla Creek in Anza, California. For more information, be sure to catch the first test of both bikes in an upcoming issue of Dirt Rider.
