South Korean manufacturer Hyosung has launched new models for 2008 that continue with it’s proven formula of combining great value with new technology and raffish good looks. These include a new 650cc fuel injected v-twin sports model, a svelte 450cc single motard and a very grown-up 125cc scooter.
It looks like a purpose built street machine and it walks the talk. It boasts 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.
The new frame is very rigid for improved handling and low vibration, using tubular chromium molybdenum (CrMo) steel and aluminium. The swing arm is rigid, but low weight aluminium and unsprung weight is reduced with lightweight 5-spoke wheels. Tyres are 120/70-17 ZR and 180/60-17 ZR. Front brake discs are 300mm with radial mounted 4-piston callipers.
Combined analogue and digital instruments, carefully located electrical components and an LED tail lamp all help to reduce weight and improve durability. Special attention has been paid to ease of riding and comfort.
The supermotard style has captured the hearts and minds of commuters and motorcycle couriers alike due to it’s unsurpassed agility in the confines of the urban jungle. Hyosung have seen the writing on the wall and are bringing their own single cylinder, 450cc supermotard style bike to the range.
The RX450SM’s 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.
The frame uses CrMo steel for lightness with rigidity. The down tube of the main frame acts as the oil reservoir and the aluminium sub-frame is a separate section for easier maintenance. The aluminium swing arm is light, but rigid enough for the most demanding conditions. The wheelbase is 1,486mm with a ground clearance of 278mm.
The 45mm upside down front fork is fully adjustable and has 250mm of wheel travel. The rear suspension features a 50mm fully adjustable damper and has 280mm of travel. Brakes are by Brembo with the wavy front disc 260mm diameter, and the rear 250mm.
The digital speedometer includes a stopwatch function. The dry weight of the Hyosung RX450SM is 120kg.
Looking more like a fully grown-up motorcycle with its 16 inch wheels and a quality finish, the SX125 scooter is still light, nimble and easy to ride. It’s designed for short trips in the city but with the added ability to handle conditions that would unsettle a traditional scooter.
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 high-tensile steel frame is strong and rigid, providing stability and low vibration. There are disc brakes front and rear, with twin coil spring and damper units at the back. There’s also ample storage space.
More goodies for 2008 from Hyosung
All Hyosung 650 V-twin engines gain electronic fuel injection for more power and torque.
The very popular GV650 cruiser gets nearly 15 percent more power and now gives a class-leading 80bhp with 67Nm of torque at 7,250rpm.
The GT650R and GT650 now have 82bhp (an almost four per cent increase) and torque of 67Nm.
At the same time, fuel injection dispenses with the choke of earlier models to give easier and smoother starting and warm-up. These new fuel injected Hyosungs are already in dealerships. The GT650X, RX450SM and SX125 will arrive in 2008 with prices yet to be set.
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. These are all very attractive bikes, and that doesn’t exclude their prices! Check out your local dealer and you might be pleasantly surprised.You can leave a response, or trackback from your own site.
