“Are you Rich?” Heading up the mountain to Mammoth Motocross? Dubach Racing Development (DRD) will be on hand for the entire two-week event and welcome racers to stop by, have their bikes tested and receive jetting advice from multi-time Mammoth Champion Doug Dubach and his staff.
“Are you Rich?” (your jetting that is!) is a complimentary service provided by DRD that enables racers to test their jetting and developed the best settings for their particular race bike. Your bike will thank you on the uphill and around John Miller Tree Turn.
