Dubach Racing Development had the advantage of spending countless hours track testing the 2010 YZ450F before any others. Doug Dubach, a 24-year Yamaha test rider, spent the summer working with Yamaha and developing the DRD YZ450F SS/AL exhaust.
With a revolution design, the DR.D “Curled” exhaust improves the stock YZ power output with a more responsive bottom hit, broader mid-top power and more overrev. Lighter, easier to repack, the option to insert provided Spark Arrestor and Dubach’s legendary ability to develop exhaust the not only provide more power but a better, smoother power character set the DR.D 2010 YZ450F exhaust above all others.
