YAMAHA WR450F (2023)

Yamaha WR450F in team yamaha blue colour

The bike for all reasons

Using the 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 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.

WR450F is designed to appeal to those born to ride – from professional enduro riders to super capable trail riders.

More powerful engine

The WR450F engine has been thoroughly redesigned to deliver stronger and more controllable performance. The new engine is essentially the new generation YZ450F tuned with enduro settings - which means it's significantly more compact and lighter than the 2021 engine.

New lighter cylinder head

The new cylinder head weighs 310g less than before and is significantly more compact. The intake/exhaust valve angles and intake port design are changed and a new piston with a small recess is specified to create a more concave combustion chamber for increased power.

Smartphone Tuning

By downloading the free Power Tuner app for IOS or Android devices, WR450F riders can easily adjust the fuel/air mix and ignition timing to set the bike up for different riding conditions.

Handlebar-mounted map switch

The WR450F features a handlebar-mounted mapping switch (blue button) that enables the rider to select one of two power maps on the fly. This simple adjustment allows instant engine delivery changes to suit variable terrain or weather conditions.

Compact electric starter

The new 450 engine is equipped with a compact and lightweight electric starter that gives push-button convenience for hassle-free starts – especially useful on the side of a hill.

High efficiency angled radiators

To ensure that the new more powerful engine runs efficiently in all conditions, engineers have developed radiators that are angled to directly face the incoming air. By maintaining a consistent airflow, this angled radiator layout delivers effective engine cooling for winning performance.

Tougher wide ratio 5-speed transmission

The WR450F's robust 5-speed transmission is built to handle even the most aggressive left foot. The specially-developed gears feature a large surface area that spread the load, and third and fourth have received a surface treatment to increase durability.

Mass-centralised wraparound exhaust

The WR450F runs a YZ450F exhaust with WRF specific muffler to achieve the goal of increased power with control. Combined with the rearward-slanted cylinder, the exhaust centralises mass and contributes significantly towards lightweight and dynamic handling performance.

New lighter aluminium frame for sharper handling

The WR450F uses the same bilateral beam frame created with controlled fill technology as the flagship YZ450F motocross bikes. But the chassis is tuned for enduro use with WR specific engine mount brackets.

Revised rigidity front end

These items have been redesigned to be lighter yet stronger to offer a better front end feel – and the bars are moved 15mm further forward and 5mm lower to help the rider get over the front end in order to improve grip and steering.

10 / 14

Industry-leading suspension

The WR450F is equipped with fully adjustable coil spring twin-chamber KYB® forks from the YZ450F that is widely regarded as being the ultimate in off-road suspension. The fully-adjustable link-type rear end settings are also revised to match the new frame and front end.

11 / 14

Stronger braking performance

Braking performance has been improved by running the YZ450F setup. This gives the brakes strong braking force and controllability in response to rider input. The caliper pistons are now larger - 25.4 mm - while revisions to the caliper body increase rigidity by 30 per cent.

New compact instrument display

A slimmer and more compact multifunction display is specified for the WR450F. The display features an odometer, two tripmeters, a clock, timer/stopwatch and a new and very useful fuel consumption indicator, while low fuel and engine warning lights are now built into the display.
