2027 Yamaha YZ450F

Meet the 2027 Yamaha YZ450F in Team Yamaha Blue—a brand-new motocross machine that looks like it rolled straight out of the paddock and onto the gate. That unmistakable blue sets the tone: focused, fast, and ready to get roosty the moment the track opens up.

At the heart of this off-road single is a liquid-cooled, 450cc, 4-stroke, single-cylinder engine with a DOHC 4-valve setup and a punchy 13.0:1 compression ratio. Feed it regular gas, thumb the electric start, and let the Mikuni fuel injection (with a 44mm injector) deliver crisp response when you crack the throttle. A 5-speed manual transmission with overdrive keeps the power usable across tight corners, long straights, and everything in between, while the chain final drive keeps things direct and race-simple.

The chassis is built around an aluminum frame with an aluminum rear suspension structure, keeping the feel light and precise. At about 243 lb wet, it’s ready to dance through ruts, snap into berms, and stay composed when the track gets rough. Up front, you’ve got a KYB inverted fork with 12.2 in. of travel, plus adjustable pre-load and rebound damping so you can dial it for your pace and terrain. Out back, a KYB rear setup with a twin-sided swing arm and 11.6 in. of travel adds matching adjustability for pre-load and rebound—because confidence comes from suspension you can tune, not hope.

Stopping power comes via hydraulic disc brakes front and rear (270mm front, 240mm rear), and the rolling stock is purpose-built: aluminum wheels wrapped in Dunlop® Geomax MX33 rubber (80/100-21 front, 120/80-19 rear), tubed for classic motocross practicality.

Details matter when you ride hard, and this YZ450F brings smart protection like a brake rotor/caliper guard, chain guard, chassis protectors, and fork guards. Finish it off with a one-piece vinyl seat at a tall, race-ready 38 inches, and mobile app instrumentation for modern insight—because the only thing better than a fast lap is knowing exactly how you got it.
