I saw it, or the pre-production one, the engine looked like a mock-up, at the NEC show last year. I thought it had been styled by the chap who did the robots in Lost in Space!
Harley did actually make a 'real' offroader/ desert sledge in 1959 XLCH Sportster. I had one ~15+ years ago it had a later seat & tank, the engine had been stroked to 1100cc ( 'too much power not enough'?)
Fine looking example of that motorcycle - the tidiness and cleanliness of the workshop / shed suggests possibly maintained by a fastidious owner with borderline OCD tendency? Good luck with the sale - where is it advertised? You should definitely put that photo in the advert
