2027 Yamaha YZ125

Dressed in iconic Team Yamaha Blue, the 2027 Yamaha YZ125 looks like it rolled straight off the starting gate—and it’s ready to keep you grinning lap after lap. This is pure motocross attitude in a lightweight, no-nonsense off-road package, built for riders who still think the best “screen time” happens between the ruts.
At the heart of the fun is a 125cc liquid-cooled, single-cylinder, 2-stroke setup with a reed valve design and Keihin 38mm carburetor feeding a gas/oil premix diet. It’s the kind of bike that makes you feel connected to every blip of throttle—simple, responsive, and made for riders who like to be part of the action. Starting is classic and straightforward with a kick starter, and when it’s time to put the power down, you’ve got a 6-speed manual transmission and chain final drive to keep you in the sweet spot.
The chassis is built to play hard. An aluminum frame keeps things sharp and precise, while KYB suspension—an inverted 48mm fork up front with 11.8 in. of travel and adjustable preload/rebound, plus a rear shock with 12.4 in. of travel and adjustable preload/rebound—helps you charge into braking bumps and float across rough sections with confidence. With 14.4 inches of ground clearance and a planted 56.9-inch wheelbase, it’s ready for real dirt, not just the easy stuff.
Braking is handled by hydraulic discs front and rear, and the bike rolls on Bridgestone Battlecross rubber: 80/100-21 up front and 100/90-19 in the rear, mounted to aluminum wheels with tubed tires. Practical protections like a brake rotor/caliper guard, chain guard, chassis protectors, and fork guards are there to help keep the ride looking as good as it runs.
With a 212 lb wet weight, a 38.6-inch seat height, and a 1.8-gallon fuel tank, the YZ125 is a lean, lively machine that turns every ride into a reason to go “one more lap”—especially when you’re doing it in Team Yamaha Blue.
