Key Features:
- A light aluminum frame housing an amazingly light and compact engine results in an awesome power-to-weight ratio.
- The YZ125 is ready to race out of the crate, complete with a ProTaper® aluminum handlebar, titanium footpegs and gripper seat.
- A pure motocross machine, the light and nimble YZ125 is the perfect choice for riders stepping up from the 85cc class.
Engine:
- Reed-valve spacer improves acceleration across the entire powerband.
- Amazingly compact 124cc reed-valve-inducted two-stroke helps produce an awesome power-to-weight ratio.
- Patented YPVS® power-valve system combines crisp, hard-hitting bottom-end acceleration with strong midrange and eye-opening top-end.
- 38mm Mikuni® TMX carburetor gives excellent throttle response and serious horsepower.
- Six-speed, close-ratio transmission optimizes gear ratios for maximum performance.

- Trick, works-style clutch lever features race-spec barrel adjuster for on-the-fly adjustability.
Chassis/Suspension:
