2006 zzr 250 battery

Hi, its my first post here!!!! I've recently bought a 2006 zzr 250 with only 6000km on it, everything on it is original no damage ect. I'm getting ready to re register it as it hasn't been on the road since 2008.
I need to replace the battery, I've tested the original and it won't hold charge. I've searched the net trying to find the right type but everything listed only spec'd for 80-90's model. Could some one please recomend a battery for a 2006? I'm on a bit of a budget so the cheaper the better.
Cheers
