I run a 2022 so im not too familiar with OG parts but that shock looks fake to me. The exhaust is a good one, the levers are cheap but common, the sliders are probably ebay as well but i cant confirm, shifter is legit, oil cooler looks like a morin cooler which is legit, grips are protaper so those are legit and good ones at that, bars look like klx110 bars which a lot of people including myself run and love them, turn signals are common and good i think, the mobber tires are sick i run those on one of my groms and love them, and the luggage rack seems legit. It looks like a common go to for people that wanna run on. I personally would get rid of that shock and go with Racing Bros or Ohlins. It looks like a knock off Ohlins and i would put money that the reservoir is just for show lol. hope this helps
