YZ450F
YZ450F is the bike to beat on MX tracks around the globe. In the hands of Dylan Ferrandis and Eli Tomac, this model has led the field in both MX and SX in the US. In Europe Jeremy Seewer and Glenn Coldenhoff have shown the winning potential while in AUS the YZ450F is both the reigning ProMX Champ thanks to Luke Clout and current 2022 series leader courtesy Aaron Tanti.
Our engineers have taken that winning package and made it lighter, more compact and boosted power across the entire rev range. The all new 450cc engine maintains the YZ450F’s exceptional pulling power and renowned ease of use, while boosting the rev limit by 500rpm for even more top-end go.
A completely redesigned aluminium bilateral beam frame provides just the right amount of strength and flex for the perfect balance of stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction allowing the rider to enter corners with greater confidence and more line choices.
For MY23 YZ450F is specced with an entirely new engine featuring revised air intake, lightweight camshaft design, new cylinder head with optimised ports and bigger intake valves, lightweight cylinder and piston, superior cooling system, lighter balancer with fewer vibes, lightweight generator system, a new ECU, plus new timing chain and tensioner.
The revisions don’t stop there because there’s a new lightweight clutch design that uses a conical spring with separate push lever for less bulk and better action, while the five speed transmission is now both stronger and lighter.
Excellent cornering performance and stability are achieved by reducing overall weight. The new lightweight chassis is more compact to give a more ergonomic riding position with optimised rigidity.
Front fork settings are also optimised while a new wiring harness, lightweight footpeg brackets, new rear axle and rear brake and integrated handlebar switch all shave weight.
To increase usability for riders, the smartphone operated power tuner app now comes with more intuitive functions.
To further cement the YZ450F’s position at the top of the tree, new styling is specified with a slim shroud, shorter front mudguard, extended front fork protectors and new flexible riding position.
