What part numbers are printed on the coil or any picture you can post of the current coil ?
SV & Hyosung in earlier days used the same coil made by Mitsubishi Japan (the long oblong ones) so no difference , however the later smaller coils are made by Hankuk Korea , and Delphi Coils are Delphi only.
So if you have a Delphi coil that looks like a shotgun , then you can only use Delphi coils as not to trip up the ECU, Delphi ECU also expects the coils to have certain resistance secondary and primary , hence the forced change over to stop older coils fitting to delphi units. Their best upgrade for the coils is good HT leads & Caps (NGK)
