The 2019 WR450F also features a lighter and compact body from front to back. The radiator is fortified with new air duct in a concave shape for better knee grip and rider’s body movements. The production of this bike also focused on the mass as a whole. Some changes made are; repositioning plastic covers, Installed with new system, redesigned one-way clutch, removing kick starter, and proper placement of cylinder to keep the bike in a lighter weight.
Engine

This bike also has rearward-slanted cylinder design complete with forward-mounted intake system and rear exhaust that features a cylinder head that works with the frame geometry for optimized weight distribution. 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.

The outer tubes are the same as YZ450F that provides a secured ground contact and handling. 25mm cartridge cylinder diameter and piston have been increased and has the flow rate of the fork oil. The mid-speed valve also changed from coil spring type to a leaf spring type to access more damping feel at low and high speeds.
The rear shock absorber is also based on the YZ450F unit and features Enduro’s specific settings that feature a coil spring with a higher strength with an 11.5mm wire diameter in 350 grams approximately. The capacity of the shock reservoir has been increased by 30cc to run cooler and achieve a more stable damping force.
