Hi, I’ve (just) got a Yammy XVS 250 Dragstar (04), I was searching the net for a luggage rack so I could carry my 2 mtr chain around with me which weights 9.78 kilos but to my surprise ALL the racks stated 5 kilo max weight, so after all that searching I’ve decided it was a waste of time so now I’m thinking along the lines of saddle bags, I don’t want to get trapped into bying the bars then find I have to buy there sadlle bags as others wont fit then be charged a fortune, how does it work? 
Please don’t suggest (as other have) carrying it around my shoulders as at that weight after a while it’ll get too heavy & the ride won’t be comfy & I consider it too dangerous if you come off. 
What stops the saddle bags from swinging out as you turn? Do you have to buy the bars? 
Do the bars stop the bags from hitting the wheel & swinging out?
