Sills recorded a flying mile two-way average speed of 204.784 mph, setting a new FIM record in the Partially Streamlined Naturally Aspirated 1000 cc class at the famed Bonneville Salt Flats, west of Salt Lake City, Utah. Sills bested the previous world record set in 2009 by more than four-and-a-half miles per hour.Erin Hunter, also an accomplished land-speed racer and ambassador for women in the sport, set an AMA national record on the same BMW S 1000 RR with a top speed of 207.758 and a two-way average of 205.566 mph (besting the previous record by over six miles per hour) at the Bonneville event.Erin Hunter says: “We’ve had the good fortune to race a number of different bikes throughout our careers, including streamliners, and the BMW S 1000 RR is incredibly stable at high speeds. The super stable platform allows us to focus on our racing skills without having to worry about the performance of the bike. You can trust it and go all out.”Gary Orr (Co-Owner & General Manager of San Diego BMW Motorcycles) says: “Andy and Erin contacted me about a week before the trials and asked if I could provide them with an S 1000 RR for Bonneville. We’ve been successfully prepping race bikes for them for the past several years, so we were happy to help them out again.”Orr and his mechanics took the production bike and installed a BMW HP Race Powerkit, a LeoVince SBK exhaust pipe, and race body work. In the meantime, Brock’s Performance shipped Orr a suspension lowering kit. With little time to spare, the race-ready S 1000 RR was delivered to Andy and Erin the day before they left for Bonneville. The couple had FastSkinz race vinyl added to the bike at the BUB event.Now in its ninth year, the Bonneville BUB Motorcycle Speed Trials continue to be solely dedicated to motorcycles. The event offers world and national record breaking opportunities and attracts top contenders in many classes.Andy Sills and Erin Hunter are avid high-speed riders with a combined 17 years of land-speed racing competition. Together, they have earned 19 world and national land-speed records with streamliner motorcycles as well as traditional race bikes.They hold a Guinness World Record for the fastest speed on a motorcycle ridden by two people simultaneously – a record achieved on a 2011 BMW S 1000 RR reaching an average two-way speed of 181.426 mph at the Bonneville Salt Flats where Andy was the rider for the qualification run (with Erin as the pillion passenger) and they switched for the record return run – with Erin as the rider and Andy as the pillion passenger. Erin also is named in the Guinness Book of World Records as the fastest female with a World Record in a streamliner motorcycle.Andy became known in the BMW community in 2005 for setting the FIM land speed record of approximately 176 mph on the BMW K 1200 S at Bonneville, during BUB’s Speed Trials. The dynamic duo will continue to race the 2012 S 1000 RR this year and next with the goal of setting new speed records. Avid BMW riders, their San Francisco garage also houses an HP2 Sport, an R1200 S and a K 1300 S.
