The 2020 WR250F was a redesigned enduro model carrying the YZ250F frame and suspension with enduro-specific tuning. The engine was reworked for stronger low and mid-range torque, and the bike gained a two-mode engine map switch, WiFi smartphone tuning via the Power Tuner app, a tougher clutch, a larger tank, a bigger skid plate and a slimmer, flatter seat.
