Faults:

Well the Hyosung I got was a piece; that's about all I can say about that.

I read the previous posts about the engine shutting off while driving. I had the same problem, the problem is from the emergency kick stand shut off switch, it's loose. When you are driving reaching the higher rpm's, it gets vibrated and thinks the kick stand went down and shuts off the bike, and when you stop and put the bike back in neutral, it will start again.. go figure.

Plus they get an over heating problem... that will never end... I have been fighting with it for a while, it's got to do with the fan quiting. Best that I can figure is the heat sensor will not trip in time... you can install a by-pass switch real cheap. I have modded other parts of the cooling system to help manage, it's almost under control, but the bike is a piece of garbage...

General Comments:

The bike would be fun if all the problems from factory are fixed when you buy the bike. It's a great bike to transition to a super bike. It can pull a wheelie first 2 gears, lots of fun, but so many problems.
