Sorry, never seen a royal star before so I have no idea. I assume the bags won't fit with my longshots anyway, that's been the problem with the last 3 sets of bags I got. My bike is used/ almost used up so I don't want to install a brand new exhaust system. Rather start looking for a fresher bike to invest in. Also it's officially winter here so won't be in the seat for some time. Thanks for the replys!
The reason the room went silent is the Royalstar is a 1300cc V4 and hopefully you know what your riding is. But yes the bags look awesome on the R*. You can still make them work without duels buy shortening plus adding turnouts.
