EP CALIPERS UPDATE

More compact, lightweight cable-actuated clutch design replaces coil springs with a new disc spring.

Updated Launch Control System now features adjustable rpm limiting for improved launches when the gate drops.

New Traction Control System communicates wheel slip to the ECU to maintain ideal rear wheel traction with three selectable levels: High, Low, or Off.

Two-mode adjustable engine mapping allows on-the-fly selection between two tunable engine maps via new lightweight, handlebar-mounted push-button switchgear.

Revised Yamaha Power Tuner App with intuitive new “Quick Setting” slide bar, Traction & Launch Control tuning, and additional new features.

Overall weight savings of 5 lb over previous model.

Completely redesigned 450cc 4-stroke engine is lighter, more compact and more powerful with an increased rev limit for longer over-rev.Other features include a push-button electric starter system with a high-capacity, ultra-light lithium-ion battery, 1-1/8-inch aluminum tapered handlebars, new compact PVC handlebar pad, new lightweight throttle cables, wide footpegs with new lightweight aluminum alloy brackets, a quick-adjust clutch perch, and new chain guide. Additionally, more seamless, rounded features including seat edges and side covers further ease rider movement for improved control. The rider triangle is also improved with increased legroom between the seat and footpegs, as well as revised handlebar position for a more natural posture and enhanced rider comfort.

A completely redesigned air intake pathway, airbox, and filter allow for a narrower fuel tank, significantly slimmer front shrouds and a lower airbox cover.

Yamaha says the result is a “better handling machine with lighter feel, improved bump absorption and increased traction, allowing the rider to enter corners with greater confidence and more line choices.”įinally, a new slimmer, flatter, and more compact body design lends a much lighter, more precise riding feel.

EP CALIPERS UPDATE

The next major update to the 2023 YZ450F involves the completely redesigned aluminum bilateral beam frame, which consists of more than 10 different aluminum components welded together, providing the opportunity to carefully tune rigidity and flex characteristics of each component. The updated Launch Control System now features an rpm limiter that can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm for optimized launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App. Three levels can be selected: High, Low, or Off. The new Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear-wheel traction. Engine mapping can now be made using an intuitive new slide bar. There is also a new lap timer, Traction and Launch Control tuning, and bike set-up guides. Additionally, a new lightweight handlebar-mounted switch allows on-the-fly selection of preloaded engine maps. Providing riders with the opportunity to fine-tune engine performance to their liking, Yamaha’s Power Tuner App has been extensively revised for 2023, retaining the full functionality of the previous version but now even easier to use with more functionality.
