<p>Presented by 6D Helmets</p> <p>Dubach Racing Development has been around since the beginning of the four-stroke revolution in motocross, as founder Doug Dubach has likely spent more time in the saddle of a four-stroke motocross bike than anyone else, factory racer or otherwise. As the lead R&amp;D rider for the Yamaha YZ400F, YZ426F, and YZ450F, Dubach has a keen insight as to what makes a thumper really perform, and he used that knowledge to launch DRD, a brand that we know well. Jehan Tetangco started as one of Dubach's employees, using his experience and expertise gained in automotive exhaust, and has been with the Doctor from the start. These days, Doug has "retired" into a not-so-quiet life, and Tetangco is now the owner of Dubach Racing Development. We relived some great memories with Jehan and got the scoop on how the transition went down in this fun episode of the 6D Helmets Midweek Podcast. Enjoy!</p>
