Racer X Films: 2021 Yamaha YZ250F Garage Build
Ted Boyko has been modifying engines for over 30 years, so we decided to give some old-school love to our new-school Yamaha YZ250F. We were looking for a little more lugability from our Yamaha YZ250F test machine to please a vet rider looking to race some local races against bigger 450cc machines. The stock Yamaha has the most torque in class in stock form, but we wanted to take it a step further without using a big-bore.
