make sure you get the EFI model (if it comes on the 250's) they are great bikes, however I would strongly urge considering the EFI 650.
make sure you get it from a reputable dealer thats close by though, because if its anything like my GT650R, you will more than likely need a few warranty repairs (luckily its a 2 year unlimited km warranty).
If you live in a coastal area, I would actually suggest NOT buying a hyosung, just because they rust easy. but if your anal about your bike maintainance, go ahead and get one. they are great bikes with a low pricetag.
If you do get one, there is a few things to remember. change the plug to NGK ones asap for safety, and get better brake pads. thats about it.
