Segment: Enduro/Offroad
Production started year: 2016
In 2016, Yamaha released the WR450F, an off-road machine that marked the beginning of the sixth generation. The bike was part of the WR series in Yamaha's range, comprised of off-road motorcycles with different engine displacements.
The 2016 motorcycle featured the reverse slant, four-valve per cylinder, fuel-injected engine that was previously used on the Yamaha YZ450F model since 2010. In addition, the Japanese maker introduced the new YZ450FX, a more enduro-oriented machine.
The 2016 WR450F motorcycle came with standard features, including fork covers, an engine guard, a high-mounted front fender, a side stand, a small front cowl with a small headlight, an under-seat exhaust system, and lightweight aluminum wheels.
The 2017 Yamaha WR450F remained virtually unchanged, except for minor modifications to the air box cover and wheel color changes from silver to black. The 2018 model was no longer available to be registered as a green sticker in California and also dropped the kick starter.
The 2019 model came with a more powerful engine and an updated frame. In addition, the bike also dropped the kick starter and included other changes, such as a more compact frame, a new speed sensor, a larger fuel tank, and an easy-access airbox.
The 2021 Yamaha WR450F model packed a new cylinder head, camshafts, piston, connecting rods, and a revised chassis.
