A 150 is stock on the rear. Its also the widest tire recommended for that 3 inch wide rim. In order to go wider a rear rim needs to be replaced. That's for a 16 inch tire. The sportster low uses a 17 inch tire and has a wider tire and rim combo.
To run a 130mm front tire a different rim has to be used and no fender will fit in the OEM forks.
The 48 has different wider triple trees than other XL models.
