Swirly wheels, shaft-drive, single front disk make it a XJ650 Maxim that came with Hitachi CV carbs and do not take well to cheap pods. It's had lots of work (custom rear frame/seat, tank knee indents and flat bottom, clip-ons, bobbed front fender) so it cannot go back to stock w/o a lot of work - if that matters. Oddly it looks like the OEM exhaust (4-2 with crossover pipe). Rear shock size is limited by shaft swingarm travel limits. Good bikes for every day riding in stock form. Looks like this one is a "brat" for shorter legged/longer armed folks.
