I can answer your question with one word...POKE. Why do idiots run tires that are way too small for the rim? It makes it handle worse & looks like ass IMO, yet they do it because it's the "cool" thing to do. Same with stretched swing arms. They started for drag racing but then moved to poser status. & yes, you lose all of the bikes natural cornering ability with them. Most people that own stretched swing arm bikes can't ride worth a s**t other than in a straight line
I'll also add that it seems to be much more prevalent the farther east you go
