We have got dozens of pictures and a few short articles about the RX450SM spread around the website. I thought I'd take the time to get it all in one place for all of us (especially new non-registered members who get linked to this site in search of the "holy grail of amateur supermoto".
(I coined that phrase :wink: )

New Hyosung 450 supermoto
By Chris Newbigging
November 14 2007 2:32 pm
Hyosung has just launched the RX450SM, an all new motorcycle to be
publicly unveiled at the NEC show next week.
The RX450SM uses Hyosung’s own 450cc liquid-cooled single cylinder
engine producing a claimed 50bhp at 8,500rpm. The engine is housed in a tubular frame which also acts as the oil tank for the dry-sump engine, and an aluminium swingarm and subframe help keep weight down to just 120kg without fluids.
The new motorcycle has a fully-adjustable rear monoshock and 45mm upside-down forks, and a Brembo caliper grabs a 260mm wavy disc at the front, and a 250mm disc at the rear. Price and colours are yet to be announced. For more information, see next weeks’ MCN, out November 21. We’ll also be videoing this motorcycle and every other new motorcycle at next week’s NEC show – click back to the site from next Thursday to see the video.

HYOSUNG AT THE NEC SHOW 2007
November 14 2007
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.
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.
