The KYB forks have a new hand adjustable compression damping adjuster for tool-less suspension tuning too – a welcome addition for many of us who ride different terrain regularly on our bikes.

The 2024 WR450F’s riding position is revised too by relocating the footrests lower to give a 10mm increase in distance between the rider’s hips and feet – and the handlebars are now moved slightly closer to the rider. Yamaha has also worked on the ECU, adapting it to the WR power with specific FI settings for more controllable power at lower rpm for enduro. “Strong, linear torque and outstanding medium to high-speed performance” Yamaha say. Finally, I printed the Elixir of Foresight model from Bugman_140 in Vase Mode to test the full Z volume and confirm that there’s no extrusion quality issue with the extruder. And as you can see, the QIDI X-MAX is able to print beautifully at lower speeds. The WR450F’s new chassis is the same overall design as the latest generation YZ450F, as you’d expect. But it does feature a number of dedicated technical changes to make it more pliable for enduro and cross-country riding.

If you go with the LRS350, there are several options for mounting 80mm, low noise fans, on thingiverse. The WR450F’s all-new bodywork features slimmer shrouds, 50mm narrower than previous models, plus a slimmer mid-section and a flatter seat profile. Combined that makes it easier for the rider to shift their body position during braking, acceleration and cornering Yamaha say.

The percentage difference between two values is calculated by dividing the absolute value of the difference between two numbers by the average of those two numbers. Multiplying the result by 100 will yield the solution in percent, rather than decimal form. Refer to the equation below for clarification. Percentage Difference = Fuel tank capacity is higher than the YZ450F at 7.4 litres (2 US Gals), there’s a basic plastic sump or engine guard and enduro muffler as standard. Although the percentage formula can be written in different forms, it is essentially an algebraic equation involving three values.Yamaha pioneered wireless tuning on its four-stroke Off Road Competition models, and the WR450F’s Power Tuner App is developed even further for the new model. Yep, the WR450F still has a wide ratio five-speed transmission and doesn’t adopt six as you might prefer for enduro and trail riding. It is wider ratio than the motocross gearbox however and with different final drive gearing it is therefore capable in a wider range of terrain and riding conditions. Percentage increase and decrease are calculated by computing the difference between two values and comparing that difference to the initial value. Mathematically, this involves using the absolute value of the difference between two values then dividing the result by the initial value, essentially calculating how much the initial value has changed. Excellent service, genuine Mira part so was a bit expensive, but I wanted a genuine part, delivered on time
