2026 Lightweight Enduro

Based on the celebrated YZ125 motocrosser, the YZ125X is optimised for the unique demands of enduro and cross country racing.


The powerful Yamaha Power Valve System (YPVS) equipped 125cc two-stroke engine is mated to a six-speed transmission for the ultimate cross country powerplant. An ultra-lightweight aluminium semi-double cradle frame is engineered to provide competition-ready handling character and composure.


It comes paired with best-in-class Speed Sensitive KYB® spring-type front fork and high performance KYB® long-travel rear shock, both fully adjustable and tuned for the specific demands of cross country racing.
