Whatever bolt pattern for whatever make and model you could ever want to know about.
I'm running some factory honda rims but I'm lucky my kinroad has 4/110 on both ends. All of the kawi bayous had 4/137s except the 250s had 4/110s on the front. Suzukis are the most oddball collection of weird bolt patterns, I'd stay away from them. If you are lucky enough to live around some bug boggers we pull the factory rims off pretty fast to put 12s (and now 14s) on bikes with bigger tires. You can normally find stock rims dirt cheap. The ones I got was given to me.
