Kawasaki GPz1100 is one of the last air-cooled superbikes – these machines were fated to die at the hands of the liquid-cooled engines. Dave Solomon from “Butchered Classics” (a community dedicated to pre-1990 bikes), modified the Kawasaki GPz1100. Starting with just a frame and tank, Dave built the “Kawasaki GPz1157”, named so due to the 1157cc engine from a Suzuki Bandit 1200! Strangely enough, the 98-hp, 16-valve Bandit engine fit into the stock engine mounts!
