Dan Dunn (owner of NRHS V-Twin Performance located in Longmont, Colorado) says: "NRHS specializes in all things Harley and Buell including CNC Headwork, Engine/Bore Kits, Dynamometer Tuning, Parts, and Services." He and the NRHS Racing Team have set the record for the "Fastest American V-Twin" at Bonneville 6 of the last 8 years."Dan Dunn says: "We consider it a Win-Win whenever you get an increase in horsepower and lower engine temperatures especially in harsh conditions like the Salt Flats. My racing team and I are very impressed with Dynacycle Oil and the way it performs. The bearings and pistons still looked new even after running multiple passes at RPMs above 7,500 for 2 miles at a time."The Dynacycle Oil Company, established in 2003, is a biker owned and operated business headquartered in central New Jersey. Dynacycle Motor Oil, a 20w-50 premium semi-synthetic blend motor oil made in the USA, is specifically formulated for all 4 stroke air and water cooled motorcycle and performance engines.
