The Timeline Motorcycle — a 24-1.2-ft.-long machine that has seven engines and carries 10 riders — evolved out of an earlier project that “Doc” Hopkins undertook in 2008. Hopkins owns Doc’s Harley Davidson, of Shawano County, Wis, and his first multi-passenger motorcycle was called the “Four-Tee-Five.” About halfway through the Four-Tee-Five build, Doc Hopkins formulated the idea of making a multi-engine bike that would illustrate the technological progression of Harley “Big-Twins” from beginning to present. The bike has seven engines: a 1200-cc 10E flathead, a 74-cid (1200-cc) flathead of 1944 vintage, a 1946 1200-cc Knucklehead, a 1948 1200-cc Panhead, a 1981 1340-cc Shovelhead, a 1993 1340-cc Evolution and a 1999 or later Twin Cam. They are mounted in a custom frame with two in-line front forks and wheels, double rear wheels and 10 seats. By June 1, 2009, the Timeline Motorcycle was starting to come together. Final assembly began July 7, 2009. By July 17 arrangements had been made to display the Timeline Motorcycle at Sturgis Harley-Davidson, in downtown Sturgis, S,D. during the 69th annual rally there. Ten people were picked to ride the bike. They left Doc’s Harley-Davidson in Bonduel, Wis., on Aug. 1, made stops in Jackson, Minn. and Wall, S.D., and reached Sturgis on Aug. 3. According to Doc Hopkins, the journey to Sturgis aboard the Timeline Motorcycle was, “definitely the trip of a lifetime.” Both the Forty-Tee-Five and the Timeline Motorcycle are on display at Doc’s Harley-Davidson (www.docshd.com). Visitors are invited to stop by to see the machines and have their picture taken with these one-of-a-kind bikes. You can also visit his free muscle car museum.
