"What really stands out about the new YZ450F is just how light and balanced it feels when riding hard," said Derek Brooks, Yamaha Motorsports Motorcycle Product Line Manager. "This new platform builds on the legendary YZ suspension and handling with an even more powerful, yet controllable engine character that will offer expert riders everything they need to compete and win at the highest level. At the same time its revised ergonomics and tuneability with the free engine mapping Power Tuner makes it easier to ride fast for all rider skill levels. I’m pumped to see it hit the tracks soon!"

Yamaha's off-road competition bikes offer the very latest in technology with performance features designed to help racing enthusiasts reach their maximum potential, win races and stand on top of the podium.

For the new 2023 YZ450F, Yamaha engineers were tasked with improving on an already class-leading package. Traditional strong points of broad, torquey power, plush suspension and predictable handling had to be enhanced, but with a distinctly rider-centric focus for the new model with a five-pound weight reduction, increased control and improved ergonomics. The end result is a lighter, more compact engine that pumps out even more power, improved handling with greater agility while still maintaining excellent stability, and a significantly lighter, slimmer body with enhanced ergonomics for greater control.

Changes for the new YZ450F start with the engine. Completely redesigned for 2023, updates include new exhaust and intake port shapes, larger diameter titanium intake valves, new forged aluminum piston, new cylinder body, crankshaft and balancer assembly, and a switch from wet sump to dry sump lubrication. The combined effect of these features is more midrange and top-end power, including a 500 rpm higher rev limit for longer over-rev, and more linear output characteristics for increased rideability and control.

Helping lay that power down to the rear wheel, an all-new cable-actuated clutch design replaces the coil springs of the previous model with a new disc spring and integrates primary gear and basket into a single steel unit. The result is a more compact, lightweight and durable assembly which yields smoother engagement and excellent feel. Additionally, an all-new tri-shaft transmission layout vertically stacks the transmission shafts, raising the center shaft and forming a triangle between the crank, drive shaft and main shaft for a lighter, more compact transmission.

Providing riders with the opportunity to fine-tune engine performance to their liking, Yamaha's industry-leading 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. 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.

The all-new Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction. Three levels can be selected: HIGH, LOW or OFF. The updated Launch Control System now features an rpm limiter which 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.

The next major update to the new 2023 YZ450F involves the completely redesigned aluminum bilateral beam frame.

Striking the perfect balance of precise cornering performance and handling stability, the new frame consists of more than 10 different aluminum components welded together. This provides the opportunity to carefully tune rigidity and flex characteristics of each component to ensure competition-level performance. 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.

Improving on the YZ450F's already category-defining suspension performance, new internal suspension valving works in combination with the new frame and body to provide exceptional bump absorption, increased traction and better cornering performance. High-spec fully adjustable Speed Sensitive System KYB® coil spring-type forks now feature a new hand-operated compression damping adjuster for simple, toolless adjustments, and the linkage-type rear suspension features a KYB® shock with damping characteristics to match the new chassis.

Finally, a new slimmer, flatter and more compact body design lends a much lighter, more precise riding feel. A completely redesigned air intake pathway, airbox and filter allow for a narrower fuel tank, significantly slimmer front shrouds and a lower airbox cover. 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, and revised handlebar position for a more natural posture and enhanced rider comfort.

Other top-spec details and convenient features include a push-button electric starter system with 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 all combine to ensure the new 2023 YZ450F continues to be the most complete, most well-balanced, most capable bike in the 450 class.

The new 2023 YZ450F will be available from dealers this November in Team Yamaha Blue for $9,899 MSRP. The new 2023 Monster Energy® Yamaha Racing Edition YZ450F will be available from dealers this October for $10,099 MSRP.

Introduced in 2020, the YZ125X was conceived to bolster Yamaha's Cross Country lineup while offering passionate two-stroke enthusiasts a dedicated enduro racer. In the first major update for the model, the all-new 2023 YZ125X reflects many of the extensive changes recently rolled out for the current competition-ready YZ125 motocross model, ensuring a high level of performance, but also incorporates a number of additional key modifications aimed specifically at boosting capability for rigorous, long distance, multi-terrain cross country racing. The result is a powerful, featherweight class-leading two-stroke woods racer that represents the ideal step up for young enthusiasts looking to enter into cross country competition or for seasoned riders, a supremely capable, lightweight and reliable two-stroke.

It all starts with a more powerful liquid-cooled 125cc two-stroke engine. Every functional part of the engine is new, including the cylinder, cylinder head, piston, piston pin, connecting rod, crankcase and expansion chamber all adding up to increased power. To enhance the YZ125X's performance in varied terrain and over long race distances, features including Yamaha Power Valve System (YPVS) characteristics, exhaust timing and compression ratio have been optimized to improve ease-of-use in the low- to mid-rpm range. Further enhancing fueling and power delivery, a new high-precision Hitachi Astemo® Keihin PWK38S carburetor with throttle position sensor and 3D-map-controlled CDI unit provide clean, crisp throttle response. A new intake design with VForce4 carbon reed valve and a straighter intake path result in an improved feeling of power in the high rpm range.

To match increased engine performance, an updated braking system features larger front pistons, more rigid caliper, and a redesigned 270mm front rotor with a 30% increase in pad contact area, all combining to provide exceptional braking power and feel. A redesigned rear rotor maintains the same braking power while dropping outer diameter from 245mm to 240mm, reducing unsprung weight without compromising performance.

Taking the YZ125X's category-defining suspension and handling characteristics to a new level, front and rear suspension damping has been revised to further improve bump absorption and cornering performance. Best-in-class KYB® suspension includes a fully adjustable Speed Sensitive System 48mm inverted front fork, now with new internals for more precise damping. Revised fully adjustable KYB® rear shock features reduced-friction Kashima Coat™ internals, separate adjusters for high- and low-speed compression damping and a full lock oil rebound system for increased comfort. Additionally, front and rear settings are fine-tuned to handle the types of demanding and varied environments commonly encountered in cross country competition.

To increase rider confidence in challenging conditions, a new flatter seat and more narrow fuel tank design, along with smoothly integrated body panels and slimmer radiator shroud width all combine to enhance freedom of movement forward and back, allowing the rider to easily shift body weight for increased control. Emphasizing its YZ racing pedigree, new front and rear fender design, bold Yamaha Blue and dark blue colorway, and premium embedded graphics provide a sharp, aggressive new look with excellent durability and scratch resistance.

Additional features on the 2023 YZ125X include premium lightweight blue Excel® rims wrapped in high performance Dunlop® Geomax MX33 tires, along with cross country oriented 18-inch rear wheel, larger rear sprocket, standard aluminum side stand, reserve fuel petcock, sealed O-ring chain, and a newly adopted scraper between the fork's dust and oil seal for improved reliability in rugged conditions. Together, it all adds up to the perfect GNCC® racer straight out of the box.

The all-new 2023 YZ125X will be available from dealers this September in Team Yamaha Blue for $7,099 MSRP.

At the top of Yamaha's two-stroke Cross Country range, the light and powerful YZ250X provides two-stroke enthusiasts with the ultimate open-class XC racer. Already known for its strong acceleration, plush suspension, class-leading handling and rider-friendly character, significant updates for 2023 incorporate similar changes made to the Yamaha's current YZ250 motocrosser to improve on key areas and provide an even more competitive, well-rounded package.

Rider ergonomics are more narrow and substantially improved through new, smoothly integrated body panels, slimmer shroud width and flatter seat. These changes allow greater freedom of movement front to back and easier weight transfer for improved control. Along with the slimmer, more aggressive bodywork, a new front and rear fender design and a sharp new graphics scheme highlight the race-focused YZ lineage. Premium graphics are now embedded to provide improved durability and scratch resistance. Additionally, updates to the seat and bodywork also enabled a new, straighter intake design, allowing a more efficient intake path to the engine for improved low- to midrange pulling power.

The YZ250X's class-leading suspension performance improves with revised front and rear damping characteristics to enhance bump absorption and cornering agility. Fully adjustable Speed Sensitive System KYB® 48mm inverted front fork receives new internals and newly adopted scraper between the dust and oil seal for improved reliability, while the revised fully adjustable KYB® rear shock features reduced-friction Kashima Coat™ internals. Settings are specifically tuned to meet the harsh demands of cross country competition.

A revamped high performance brake setup provides exceptional braking power and feel with a more rigid front caliper, larger front pistons and redesigned 270mm front rotor that increases pad contact area. A redesigned rear rotor drops the outer diameter from 245mm to 240mm, reducing unsprung weight with no compromise on performance.

The 2023 YZ250X uses the same fast and fun liquid-cooled YPVS-equipped 249cc two-stroke powerplant as its YZ250 brethren, but with YPVS characteristics, exhaust timing and compression ratio optimized to improve ease-of-use in the low- to mid-rpm range for improved cross country performance. Additionally, clutch durability is enhanced through a new friction material with excellent heat resistance characteristics ideal for long distance racing, without compromising on smooth operation.

Finally, premium lightweight Excel® wheels combine with high performance Dunlop® Geomax MX33 tires, cross country oriented 18-inch rear wheel size, wide-ratio gearing, standard aluminum side stand, sealed O-ring chain and a reserve fuel petcock to complete the ideal high performance two-stroke XC competition machine.

The new 2023 YZ250X will be available from dealers this August in Team Yamaha Blue for $7,999 MSRP.

The remainder of Yamaha's Motocross and Cross Country lineup, including the YZ65, YZ85, YZ85LW, YZ125, YZ125 Monster Energy® Yamaha Racing Edition, YZ250, YZ250 Monster Energy® Yamaha Racing Edition YZ250F, YZ250F Monster Energy® Yamaha Racing Edition, YZ250FX, YZ450FX, WR250F and WR450F all return unchanged for 2023.
