NEW BIKES PLUS POWER AND TORQUE INJECTION FOR HYOSUNG
New 650 and 450 bikes and fuel injection upgrade for NEC Bike Show
New 650 and 450 bikes and fuel injection upgrade for NEC Bike Show
New 650 and 450cc bikes, a new 125cc scooter and technical upgrades including fuel injection mean riders are set to take Hyosung just a little more seriously when the South Korean manufacturer debuts its new bikes at this year’s NEC International Motorcycle Show.
New GT650X
The star of the stand is likely to be the new Hyosung GT650X – a different and individual take on the street-fighter style with a completely new tubular frame and sharp styling. The engine is a development of Hyosung’s familiar 647cc 90 degree V-twin, with double overhead valves and four valves per cylinder. But with electronic fuel injection, power output is now 82bhp with improved fuel efficiency, more low speed torque (67Nm at 7,250rpm) and stronger performance. Vibration is minimised by counterbalancing and a new oil cooler aids performance and durability. The exhaust system is kept low and central for mass centralization.
New RX450SM
For the first time, Hyosung is bringing a single cylinder, 450cc bike to the range. The new RX450SM is unashamedly a supermotard-style bike, designed for serious fun, but it would also make a great city commuter bike. It was designed using Hyosung’s ‘form follows function’ philosophy; it has a simple, elegant line, yet looks very purposeful.
The engine is a liquid-cooled DOHC four valve single cylinder, 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. Vibration is reduced by counter-balancing. Power output is 50bhp at 8,500rpm.
New SX125 scooter
Conceived as short-to-mid range urban transport, the new Hyosung SX125 scooter is compact and very easy to ride, but with 16 inch wheels and a quality finish, it can easily handle today’s rough roads and looks every bit a serious piece of machinery.
It is powered by the same 125cc engine found in the Hyosung MS3 introduced earlier this year. The single cylinder 124cc engine uses double overhead camshafts and four valves with water cooling. An electric starter and automatic CVT transmission make for easy riding, and the SX125 has been designed for comfort with little or no fatigue.

The GT650X, RX450SM and SX125 will arrive in 2008 with prices yet to be set.
Every model has a full two year warranty and one year’s roadside assistance.
There are currently 16 models in the fast-growing Hyosung range from 125cc to 650cc, including cruisers, sports and commuter bikes, supermotard and off-road, scooters and a road-legal quad. Prices range from £1,949 to £4,999.
Hyosung range is available at 88 dealers around the country and on-line at
The Hyosung stand at this year’s Bike Show will be in Hall 1 from November 23 to December 2
