I think its just because I'm used to seeing sportsbikes with wider rear tires.
The Rs thats parked next to the speedmaster has a 180 section rear but it looks much wider than the 170 on the speedy.... I know It shouldn't but it does.

Im wondering if its the lack of chicken strips on the sports tire and the inch wide ones on the cruiser that make the cruiser look narrower


hmmm funny line to follow
