New 2015 Hyosung GT650 in black. Comfortable ergonomics with power to spare - our best performing sportbike is also available in naked trim. The GT650 is nearly identical to the GT650R, but with minimal bodywork and a less aggressive riding position. The GT650 naked is all about serious performance AND serious comfort. It all starts with a rigid chassis, adjustable upside down forks and rear shock that gives precise handling and feedback. The 650cc 90-degree DOHC 8-valve fuel-injected V-twin engine delivers peak power and a broad usable power band.
