With its rearward-slanted cylinder and innovative reverse 4-valve cylinder head featuring a highly efficient front-facing inlet, this hugely capable motorcycle has reaffirmed its status as one of the most competitive motocross bikes at every level. Its ability to win 'straight from the crate' - combined with Yamaha's high levels of reliability and durability - has made the YZ450F the clear choice amongst many local, national and international racers.
Yamaha's engineers have focused on honing and refining the YZ450F in order to maintain its winning advantage - whilst at the same time delivering even higher levels of performance, controllability, feel and usability. Yamaha's MX development team persisted in thinking forward to introduce a wide range of engine and chassis changes to bring the YZ450F to the next level, with 4 key objectives:
Achieving a smoother and easier engine character for enhanced controllability and usability without sacrificing power output
More effective bump absorption, as well as improved controllability, traction and front grip feeling
Improved braking power and controllability
Faster race starts using an electronic Launch Control System
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.
Races can be won or lost in the charge from the start to the first corner, and in order to give Yamaha riders a key advantage, the 2016 YZ450F is equipped with a sophisticated new Launch Control System (LCS) for smoother and quicker acceleration off the start line.
The exhaust pipe has an innovative layout, circling the cylinder, giving the exhaust pipe proper length for an excellent exhaust-pulse effect. At the same time, the exhaust pipe has three different diameters throughout the exhaust tract, bringing out excellent power characteristics. This new layout allows the silencer to be positioned forward behind the side panel closer to the middle of the bike which centralises the mass for superior handling.
A new layout for the fuel tank and air cleaner box gives the machine a slimmer feeling between the legs as well as position's the fuel tank mass closer to the centre of the bike which improves handling feel. Furthermore, the air box can now be accessed with quick release fastners for easy serviceability of the large air cleaner element.
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.
The 2016 YZ450F is now equipped with a new large diameter 270mm front disc that not only delivers higher levels of braking force - it also gives plenty of feel, enabling the experienced rider to use the system more effectively.
