Yes - that is a stock rear end with the foot-peg hanger just in front of the rear shocker. As you say the bike you photo'd is on stock pipes.
If you look at my 'XR' there are currently no foot-peg hangers and a new bracket is located there which then acts as the upper pick-up point for the rear shocker - this effectively jacks up the rear end (Said to assist handling) - but also raises seat height
I actually want to retain the jacked up look as it makes it look whacky - especially with the tail tidy, which exposes a fair chunk of the rear tyre .... the look from the rear really throws you - you'd never guess it was from the dark side (except for the noise
). But I also want pillion foot-pegs (Which I managed to source second hand). I have got a set of race spec rear shocks, which are longer than stock & pick up in the standard top mount on the chassis. They have a small amount of height adjustment at the lower eye, & I intend setting it up on the shortest shock length, so it will be sat slightly squatter than it is at the moment.
The bike you photo'd has the same rear rack as I acquired - but I've also got the small backrest pad for the pillion for when Les feels the urge to feel the dark side !
I like the pillion seat tail pack on the bike you saw ! - I could tour with that on ! .... but there's only a small tank on the XR (Like it is on all sportsters). But I'm sure you could get by. (In reality I would bungee one bag to the tail-rack & the other on the pillion if I was solo tour riding on the XR).
Did you chat with the 'XR' owner ? ... When I have done, I've never found one that was significantly disappointed with the XR ..... but I suppose they are that marmitey that if you took the plunge to buy one, then you're half sold on the concept anyway.
Glad you got chance to see an 'XR', there aren't that many about.
