November 27, 2007 South Korean manufacturer Hyosung has launched new models for 2008 including a new 650cc fuel injected v-twin sports model and a 450cc single motard.
GT650X The new 82bhp GT650X features electronic fuel injection, vibration is minimizing counterbalancing and a low slung, centered exhaust system for mass centralization. The rigid frame provides improved handling and low vibration via tubular chromium molybdenum (CrMo) steel and aluminum and unsprung weight is reduced with lightweight 5-spoke wheels along with combined analogue and digital instruments, carefully located electrical components and an LED tail lamp.
RX450SM Hyosung have seen the potential in the supermotard style, bringing their own single cylinder, 450cc supermotard style bike to the range. The RX450SM is powered by a liquid-cooled DOHC four valve single cylinder producing 50bhp at 8,500rpm, with an aluminium silicon (Si) sleeve for more power and durability. The aluminium alloy comprises over 30 per cent Si and is the only alloy of its type currently in production. A PF die-cast piston is more durable and exhibits less thermal expansion than normal cast and applied steel (FE) pistons. The down tube of the main frame acts as the oil reservoir and the aluminium sub-frame is a separate section for easier maintenance. A digital speedometer includes a stopwatch function and the dry weight of the Hyosung RX450SM is 120kg.
