As a lightweight 207-pound (claimed) dirt bike, the 2020 Yamaha YZ125 presents itself as a nimble option for teens who are moving up in displacement and looking for a full-size motocross competition bike. Its aluminum frame, subframe, swingarm, and handlebar help keep weight down while the reed-valve-inducted two-stroke engine delivers 125cc of power throughout the rev range. It is race-ready with front and side number plates, fork guards, fully adjustable KYB suspension, and Dunlop knobbies.

2020 Yamaha YZ125 Reviews, Comparisons, And Competition

Beside the newly introduced cross-country-focused YZ125X, the YZ125 continues to bring its racing roots to the track. Past impressions of the MX model from sister brand Dirt Rider found that the YZ125—and YZ250—are bikes “known for their excellent powerplants and great handling.”

The 2020 Yamaha YZ125 is similarly priced to the KTM 125 SX ($7,299), Husqvarna TC 125 ($7,399), and TM MX 125 ($8,395).
