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.
