The Yoshimura Tornado S-1 is a 50-unit limited superbike based on the first-generation Suzuki GSX-R1000. Its 988cc inline-four was extensively reworked and delivers more than 170 hp at the rear wheel. Ohlins suspension, six-piston Nissin brakes, BBS wheels and full carbon bodywork make it the most elaborate road-going build in the company's history. It was sold in Japan only.
