My saddlebags fit with or without my detachable sissybar. I got them from www.leatherup.com for about 60 bucks !
Not sure on how much they charge to ship to Aus.. i was lucky enough to have a friend in the US bring them over for me with their luggage.

yeah but if wanted anything bigger i woulda got me a roadking and not a sportie

yeh i got the sissybar luggage set off that site as well.. its frickin huge and holds a lot of stuff.   Could never carry the all missus' stuff in the throwovers...

I mainly use the throwovers for when i need to take a few things work that wont fit in my satchel bag.... including my lunch...
