The Yamaha YZ125 is widely considered one of the best 125cc motocross bikes on the market as of 2016. Though not as fast in a straight line as some competitors, the YZ125's combination of low weight, agility and affordability make it a viable overall choice in its class.
The Yamaha YZ125's aluminum frame construction is a major contributor to its handling and light weight. Many riders find that they can brake harder into corners on the YZ125 than on other bikes and accelerate sooner, making up for the YZ125's disadvantages in straight-line speed. However, the YZ125 does require an aggressive, high-revving riding style to make the most of its power.
