Double Trouble: Hot Chop’s twin-engined Harley drag bike

Squeezing two Harley engines into one chassis is a special form of lunacy, most commonly found in the drag bike scene in the USA. In the glory days of the mid-70s, Bonnie Truett linked a pair of Sportster motors and nitro-injected them. A decade later, Elmer Trett built an even faster twin-engined bike: the ‘Freight Train,’ which ran the quarter mile in under seven seconds. Despite the wealth of tuning talent in Japan, no double-engined Harley has been built there—until now. Kentaro Nakano is the man who has broken the drought, by creating the engineering masterpiece we’re looking at here....
