Race-developed over a three year period, the YZ125H was the first liquid-cooled Yamaha motocrosser. The alloyed aluminum radiator was mounted to the top triple clamp. Coolant was channeled through the handlebar crown, steering head pipe and the down pipe of the frame. Liquid-cooling helped minimize heat-induced power loss racers experienced during a race.
