When Suzuki introduced the X6 in the fall of 1965, it caused an immediate sensation. Developed with the goal of captivating the U.S. market, the Hustler was designed to be the fastest 250 cc motorcycle in the world. The bike featured Suzuki's first ever tubular steel double-cradle frame, and its air-cooled two-stroke sleeved aluminum cylinder engine was capable of just about 100 mph. Surprisingly sophisticated, this little engine achieved 100 hp per one liter cylinder volume, which meant it could outrun most of the bigger, faster bikes on the road. It featured automatic oil injection, but more importantly, it was the first six speed motorcycle ever to go into full production.
