New model release season has arrived, and kicking things off is the 2026 Yamaha YZ450F. A warm, windy day at Appin’s Macarthur Motorcycle Club set the scene, where MotoOnline was on location for the media ride day to put the bike through its paces in this Tested review.

The YZ450F has a long history of evolution, from the first reverse engine back in 2010 through to the race-proven 2025 model. Why improve an established winner? And if you try, can it really be made better? On a relentless mission for success, Yamaha set out to refine it further – and improve it they did. Additional tech information can be found in Detailed.

First impressions on the bike are positive. The cockpit feels comfortable, the handlebar layout is clean, and the flat seat gives the sensation of sitting on top of the machine. Plus, a new hydraulic clutch comes standard, delivering a firm, yet smooth feel.

Hitting the track in stock trim, the engine immediately stands out. Its unique configuration is known for its strong power delivery, and this bike doesn’t disappoint. If you haven’t ridden a Yamaha before, the induction noise from the air-box takes some getting used to. Part of the 2026 changes focus on noise reduction, and while the induction note is quieter than the 2025 model, it’s still noticeable to the unfamiliar ear.

The new textured seat cover is a big improvement, since it allows you to move freely forward, yet grips under acceleration to stop you sliding back. Early laps revealed the stock maps felt a little lethargic for me, particularly when running third gear in tighter corners. The power was mellow off the bottom, then built aggressively through the mid-range, creating a light-switch effect that hit hard once it came alive.

The first adjustment I made was sag, going from around 106mm to 99mm. The rear felt too low and the bike tended to climb out of ruts when exiting turns. I also used the Yamaha Power Tuner app to create a more aggressive map and assigned it to map two. Both changes made a big difference.

Balance-wise, the bike felt more stable, improving corner entry and exit, though it still had a tendency to climb out of ruts mid-corner under throttle. The new engine map, however, was a huge improvement. It freed up the engine, sharpened response off the bottom, and allowed me to hold higher gears through most corners. With more time and tuning, I believe I could create a map that hits the sweet spot for my style without extra cost – a brilliant feature of this bike.

My final change was sliding the forks through the clamps by five millimetres from the stock position, giving it a slightly steeper turning angle. That adjustment settled the front-end mid-corner and let me carry more speed consistently. I still find the YZ450F is a bike that you need to be precise with when selecting lines into turns, I felt like I had to set up my lines early as it still feels hard to alter lines late.

Dunlop was also on site with the all-new MX34 tyres fitted across all test bikes. Designed for soft through to intermediate terrain, they handled both conditions well. I started with 15 PSI, but dropped to 13, which gave the front and rear noticeably better feel.

From a technical standpoint, Yamaha has introduced a host of changes for 2026. The YZ450F now features a new shock with a slow-speed compression adjuster, paired with revised suspension settings at both ends to refine balance and handling.

Chassis updates include a redesigned downtube for altered rigidity, asymmetric rear engine mounts, and slimmer, two millimetre front engine mounts to further improve flex characteristics.

To meet incoming sound regulations, the 2026 YZ450F is also fitted with a quieter air-filter system and low-noise muffler, complemented by revised intake ports. Other key additions include a standard hydraulic clutch, a new piston cooler, an updated magneto, and the redesigned textured seat cover that enhances rider comfort and control.

Who does this bike suit? I believe a wide range of riders could enjoy the YZ450F at any track. Its ease of tuning is a standout, and while it’s a great choice for a local racer, it’s an ideal platform for privateers thanks to its strong, tuneable engine, capable suspension, and Yamaha’s extensive genuine parts and accessories range. Straight off the showroom floor, it’s competitive.

The 70th Anniversary Edition includes everything the base YZ450F offers – from a redesigned frame and updated engine and suspension to the new hydraulic clutch and anti‑theft ECU‑lock – but it sets itself apart with striking, race‑inspired white-and-red ‘speed block’ livery, celebrating seven decades of Yamaha’s racing heritage.

All-in-all, it was an epic day. The Yamaha and CDR teams were outstanding, providing support and insight throughout. The 2026 Yamaha YZ450F is a seriously impressive machine and well worth a look if you’re in the market for a new bike.
