Hi from Sweden

I have a Hyosung TE450 Rapier (swedish name anyway), and I need a new rear wheel hub. Do you know where to buy these? Is it the same as on the Suzuki LT (Z) 400?
Mine is 4x110mm, 20 splines i think. The LTZ is not so expensive, but the Hyosung is...
If you have any advice where to buy these at resonable price, I would be very glad for that information.
