this is correct. I believe they built the engines and possibly frame for the 1st gen sv’s or at least the 650. Hyosong’s first bike here that I saw was in 2004 I think and it was an exact copy of a standard SV.
That said, I have no idea what it’s like to try to get parts for one. Something as simple as fork seals may cause a major headache, or it may literally be the exact part suzuki uses. General consensus is that while they may be cheap and new, you are probably better served buying a 2 or 4 year old ninja 250, or a 5 year old SV as it will be more reliable. Both of those bikes, the ninja and sv, have great aftermarket support, parts are plentiful, and especially in the ninja’s case, super cheap since you can go back to 1988 and find the same stuff. Present model year excluded (and that may just be plastics that changed)
