I have a question... Do they make an aftermarket back passenger seat for a 2009 Can-Am Outlander 400 EFI? Looking for one with a backrest for my wife when she tags along.
Does your floorboard have another higher step at the back where a passenger could rest their feet? If yes it's a max and you can put a factory rear seat on it. If no then have to go another route.
Go on Amazon or ebay look up quadboss weekender trunk or wes classic seats they get mounted on your back rack with u-bolts I prefer the quadboss.. You can also look at wes foot pegs they work nice
