More Powerful and Compact Engine
Equipped with a high compression cylinder head as well as a durable forged piston and aggressive camshaft profiles, the compact 450cc engine gives you the best balance of race-winning performance together with ultimate controllability. Delivering torque-rich power right where you need it, the YZ450F has the ability to take you to the top.
Yamaha Smart Phone Tuning
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 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.
Adjustable Mapping Switch
After pre-programming the YZ450F, there's a handlebar-mounted mapping switch (blue button) that enables the rider to select one of two 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.
Industry Leading Suspension
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 ideal balance between handling and bump absorption, these exceptional front forks deliver best-in-class performance.
Launch Control System
The YZ450F's Launch Control System (LCS) optimises the engine's power output and running characteristics during the first few seconds of the race after the gate drops. By helping to transmit power more efficiently, the LCS gives greater controllability and traction off the line, increasing the rider's holeshot-winning performance and giving a real advantage in the crucial charge to the first corner.
