The matched rims will give it a badboy look. Alot of people do rear swaps when converting 80s cruiser style bikes into cafe racers, like the Virago.
Golden boys are a joke, I ordered Shinkos for my CM185 and the ebay seller sent me those, I returned them, they were crap, I mean crap. I gave him a negative feedback with a few things thrown in.
It was hard to find tires for it so I ended up with Kendas, they fit the bill for this bike, with the old school Conti style tread pattern. The stock size fills the rim just right.
