What's the maximum width for rear tyre on standard 2000 fatboy swing arm ?
Cheers
its not the swing arm that's the problem ,its the frame horns ,not sure about your rear guard but with a bobtail 160/70/17 metz oem 4.5 rim new spacers /pulley spacer maybe some brake caliper machining or just put a 150 on it like most with tyre bulge
