WOW! Amazing results from such a simple upgrade
Take Your YZ125 & YZ250 Suspension to the Next Level
The 2017+ Yamaha YZ125 and YZ250 carry the legacy of some of the most iconic two-strokes in motocross history—light, agile, and built for pure fun.

At Motaero, we specialise in taking KYB-equipped Yamahas and refining them for maximum performance.
