Inside, the engine features a straight intake tract, aggressive cam profiles, high-compression “box bridge” piston design with DLC-coated piston pin, and more.

Just like YZ450F, this 5-speed transmission bike is also equipped with Yamaha reverse cylinder head engine and enduro intake and exhaust systems, fuel injections and ignition advance maps. Yamaha says the new high torque engine produces “a broad and linear spread of useable power. With an excellent feeling of traction, the WR450F delivers harder- hitting performance for winning times on enduro special tests.
