2015 Yamaha YZ250F First Ride Review

The YZ250F’s fuel-injected, DOHC, 249cc engine features a 6.2-degree reward slanted cylinder and reverse cylinder head configuration with a straight downdraft intake and symmetrical ports. The combination yields a compact powerhouse that centralizes the engine’s mass in the chassis. Yamaha has revised the exhaust cam to make the ’15 model much easier to start.
