Sito Big Boy Slip-On Chamber aftermarket or carry a passengerVintage slip on chamber from Sito. Right side mount. This one is a lot larger than most. We think it might be for a shifter bike. There is a small bit of the seam removed where a foot brake might go. Maybe this would work on a Cimatti 86 or similar? Vintage and old. In good shape but small amounts of bubbling paint in a couple areas, a little rust in spots, even a small ding. This things older than the internet so that's expected. Overall length is 31
