GSX250 Help Needed, What Sprokets do they use?

[doa]

I have a 2003 GSX250 and need a new chain and sprokets, only prob is we cant find what we need in the way of sprokets, we know suzuki have genuine rear but no fronts, but i dont want a genuine and we cant find any conversion info for what after market ones it takes. The only numbers on the rear are 44-520, which is the amount of teeth and size chain, i'm hoping to find someone that has replaced one and can tell me what the aftermarket ones are for this bike are.
