2020 Yamaha YZ450F

To reduce weight and fine tune the bike's instinctive handling performance, the new bilateral frame features thinner main spars together with thicker bottom tubes and new engine mounts. These significant changes - together with the mass centralised design and class-leading suspension - help to deliver even sharper handling for reduced lap times.

By downloading the free Power Tuner app for IOS or Android devices, YZ450F riders or mechanics can easily adjust the fuel/air mix and ignition timing to set the bike up for different tracks and changing riding conditions. This feature makes the 2020 YZ450F the most adaptable motocross machine that can be tuned instantly at the trackside, enabling its rider to master a wide range of surfaces and weather conditions.

After pre-programming the 2020 YZ450F, there's a handlebar-mounted mapping switch (blue button) that enables the rider to select maps on the fly. This simple adjustment allows instant mapping changes to suit changing track or weather conditions, from a super-aggressive map for fast dry tracks to a more useable map on muddy surfaces.

The YZ450F is equipped with fully adjustable coil spring twin chamber KYB® forks that are widely regarded as being the ultimate in off road suspension design. Featuring new settings and speed sensitive damping that gives the idealised balance between handling and bump absorption, these exceptional front forks deliver best-in-class performance.
