Hyosung is just starting to take off in Oz, with 250 sports/cruizer/scooter and 650 sports. I spoke to some people, and while I wouldn't think a hyosung would be a great bike if you wanted to keep it for, say, 10 reliable years, they are not far off!
Hyusung have buily many Suzuki models and apparently wanted abit more of the limelight, but the big S wouldn't have a word of it - so off they went and into the worldwide marketplace, and are selling fairly strong. The Comet 650 actually puts out more power than the SV650!
This is not another supermarket kids bike brand, the Korean's are comming (remember what everyone said about those strange Japanese bikes in the 50's and 60's, and more recently what we said about cars like Hyundai? You wait 10-15 years and see...)
