2021 Yamaha WR450F: First Look

3 months ago | Words: Andy Wigan | Photos: Yamaha Motor Australia

It was just six months back that Yamaha’s much-updated 2020-model WR250F arrived in Aussie dealers. And today, the Japanese manufacturer has given us our first look at the 2021 WR450F; a machine that appears to be a significantly updated from its predecessor and incorporates a majority of the mods that appeared on its MX cousin, the YZ450F, a year ago – albeit with enduro-specific settings. Yamaha Motor Australia (YMA) confirmed that the 2021 WR450F should be in Australian dealers before Christmas, at a ‘Ride Away’ price of $15,499 (that includes GST, freight, pre-delivery, and 12 months registration).

So, specifically what’s new and/or improved on Yamaha’s 2021 WR450F? Well, here is what today’s PR from Yamaha Motor Australia revealed:

Development input by a range of Aussie enduro riders over the years is one reason the WR450F continues to outsell its competition. Continual updates based on the equally successful YZ450F MX weapon is another. And for 2021, the all-new WR450F is fully reworked with technology that has been forged in the intense heat of MX competition. More power and sharper handling are the result. To create an enduro bike with the flexibility to tackle tough trails and win races, the YZ platform has been extensively tested and tuned with enduro-specific settings.

Using the 2020 model YZ450F as a starting point, our experienced development team – including Kiwi race team manager and Yamaha legend, Josh Coppins – came up with an enduro weapon that turns, stops and goes better than ever before. The 2021 WR450F produces bulk power, but transmits that power to the ground in a more controllable manner with additional traction at both wheels.

Sporting a new aluminium bilateral beam frame, the WR450F feels lighter, is easier to turn in tight situations and has improved stability both in the bumps and in the air. Progressive, smooth KYB suspension continues to absorb big impacts and the braking performance is now improved.

The 2021 WR450F is designed to appeal to those born to ride – from professional enduro riders to super-capable trailriders. The new model comes in the new Team Yamaha Blue colour scheme that echoes its YZ and FX cousins in the VictorYZone.

Pricing is set at $15,499 including GST ride away including 12 months registration, with availability due for December, 2020.
