Like the FX model, the new WR comes stock with electric starting, a skid plate, an 18-inch rear wheel, and a kickstand. In front, the off-road models both have 4.5N/mm fork springs (compared to the 5.0N/mm front springs in the MX model) and all three 2016 450s share the same rear shock rate, a 56N/mm spring. Each of the three Yamaha 450s has its own valving spec. Of course, the off-road models each feature a wide ratio transmission and a different clutch with updated fiber material, a judder spring, lighter clutch springs, and a revised clutch actuator arm with a different cam on it. The WR also gets an O-ring chain, MX51 tires, a cooling fan, a taillight, a spark arrestor, an enduro computer, and a headlight.
