I find the body work on the Burgman fairly easy to remove compared with the Honda deauville I had before, it gets easier with practice of course. I don't use the bike much in bad weather so the filter stays fairly clean it is important to check it though. I have used both man cave and mitch's sites but I find the best one is LeDudes

Have you had the burgman long?
