About a month ago, we featured one of Scholtka's most fascinating exploits, a Ducati 848 EVO subjected to a neo-retro cafe racer conversion. To be honest with you, we can’t seem to get enough of this fellow’s two-wheeled artwork, so the urge to feature yet another one of his ventures was simply irresistible. This time around, the project in question began with a stock 1984 MY GPZ900R Ninja from Kawasaki’s lineup. Its liquid-cooled 908cc inline-four mill boasts four valves per cylinder and a solid compression ratio of 11.0:1.
