Take a stock 2020 YZ125 and make it even better. That’s the mission of MotoHead’s Dave Willet, a former British 125 champion with more experience of the YZ125 than just about anyone else on the planet. From jetting to squish, pipes to clutches and more, he talks through the initial set-up of the smokin’ YZ! It’s like one man’s personal love letter to his favourite bike!
