Featuring a reversed cylinder head layout, forged aluminum piston, titanium valves, lightened crank assembly and dry sump lubrication, the 2024 YZ450F's advanced DOHC four-stroke engine is light, compact and world renowned for its incredibly broad pulling power across the entire rev range.
And like having factory team support in your pocket, Yamaha's groundbreaking Power Tuner App allows owners to adjust air/fuel mixture and ignition timing to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.
YZ450F’s revolutionary rearward-slanted-cylinder design is an innovative approach to achieve unmatched mass centralisation. Concentrating the motorcycle’s heaviest components (engine mass, fuel tank, exhaust system, and airbox) toward the centre of the machine helps achieve superior, nimble handling.
The aluminum Bilateral Beam frame has been refined further, the swingarm's pivot assembly is 12mm wider, and the aluminium frame's lower rear section is modified to accommodate this stronger design. Redesigned steel engine mounts also contributing towards the increased rigidity of the chassis - and to lower the rider's centre of gravity and give greater freedom in terms of body position, the footrests are mounted 5mm lower.
Optional accessory, GYTR Power Tuner lets bike tuners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions.
