Why you’ll love the 2027 Yamaha YZ125
For sale at Vallely Sport & Marine in Bismarck, ND
The 2027 Yamaha YZ125 stands out with its compact, high-revving 125cc liquid-cooled 2-stroke engine and a precision Hitachi Astemo® Keihin PWK38S carburetor that deliver responsive power where you need it most. This machine merges race-ready tuning with a sleek, purpose-built chassis for nimble handling on tight tracks and spirited backroads alike. Its light 212 pounds of wet weight keeps agility at the forefront, letting you flick between corners with confident balance.
Capability and ride quality are defined by its suspension and geometry. The front suspension uses a KYB® Speed-Sensitive System inverted fork with 11.8 inches of travel, paired with a fully adjustable KYB® rear single shock offering 12.4 inches of travel for planted stability over rough surfaces. The compact body measures 7.01 feet in length and 2.71 feet in width, while a 4.25-foot height and a 4.74-foot wheelbase contribute to a responsive, flickable ride. Fuel capacity sits at 1.8 gallons, keeping you in the saddle longer between fill-ups. The engine breathes through a reed-valve induction system, and the compression ratio ranges from 8.2 to 10.1:1, delivering a balance of punch and controllable power.
Design and construction emphasize durability and precise control. The transmission uses a constant-mesh 6-speed with a multiplate wet clutch, ensuring smooth engagement and reliable performance across laps. Overall dimensions and weight distribution work in harmony with the chassis geometry to maximize cornering confidence and traction. The combination of premium components and compact packaging makes the Yamaha YZ125 a focused machine for riders chasing track pace and daily impulse to ride.
