Solitary Confinement is a 1957 Triumph built by Mark Drews in 2010 that got its first public outing at the Mooneyes Yokohama 2011 Hot Rod Custom Show in three weeks. Mark used Harley-Davidson peashooter forks, a micro spool hub and a bicycle-type rim and tire at the front. The tank has an inner steel vessel with an outer cover hand-carved from Lucite—yes, that 1960s space age transparent thermoplastic. Fueling is reported to come from dual 389/689 Amal carbs, and there’s a hand-made micro flask oil bag with the original pre-unit fittings adapted to fit. The primary cover and motor mounts are also crafted from Lucite. The simple black and silver colors work well with the beautifully balanced 60s-style aesthetics, proving that less is usually more when it comes to retro custom builds.

Built In: U.S.A. Bike Style: Bobber
