I agree, the Koreans are capable of making excellent quality stuff, but the Hyosong is just not of the same quality as an SV650. I'll say it again: I've seen them practically side-by-side, and the Hyosong is just not up to par with the SV650.
It would not surprise me if Hyosong manufactured the engines for Suzuki under contract, but the terms of the contract determines the quality, sometimes even more so than the manufacturer. Plus, the engines do not even LOOK the same. As Michel says, even if they did look the same, the quality could be EXTREMELY DIFFERENT, even if delivered from the same plant, due to different manufacturing tolerances in the contract, etc.
By the way, I don't consider a dealership mechanic a reliable source, either. I believe that spreading mis-information can be very damaging. Someone might be fooled into thinking that the Hyosong is the same bike as the SV650 for $1000 less, only to find out that they got a cheap knockoff that has less power, is heavier, handles worse, may prove to be less reliable, and will most definitely have a much lower resale value than the Suzuki. Honestly, even the plastic is cheaper.
So, Outlaw, what makes you so concerned about the Hyosong being the same as the SV650? You seem to be very aggravated over me trying to get the facts straight.
