We have tried to show the most popular bags for specific years, makes and models.  With some modifications the larger bags may fit.  We don't want people buying bags that we know won't work on stock bikes so we don't show them.Smaller bags will usually work but since the average customer wants as big as possible we don't list the smaller bags. We don't always know which tool bags and windshield bags work on some bikes, so they are not listed where they may work just fine. We find that if you know it will work then it usually does.If you are sure that a different bag will work feel free to buy it, we will be checking all orders so if we have any question about your choice we will contact you.If you want to ask a question about a specific fitment feel free to call 888-265-9650 or email sales@leatherworksinc.com
