The Enfield that Shahid rides is supposed to be a vintage with BM series registration number. Royal Enfields from that time were infamous for having the kick start on left side and gears on the right making them quite difficult to ride for an average rider. The bike shown in the movie is clearly a modern day version of the bike with kick start on the right, and not an authentic vintage.
The story of the movie is based in Delhi but certain characters like Autorickshaw driver, Kabir's maid are seen to be talking in 'Marathi' language which gives impression that the movie is based in Mumbai.
