This is the later carburetted GT 650S, a half-faired V-twin roadster presented as evidence of Korean makers catching up with Japan. Reviewers liked the torquey 4,000 to 8,000 rpm range and the suspension, but found the brakes mushy, the riding position cramped and the instruments hard to read in sun. It undercut the Suzuki SV650 on price.
