You’ve given the part no. RAT000539 – this matches the J-platform rear-wheel spacer line that’s published everywhere as RAT00539 / RAT00539/C – “SPACER – DISC SIDE” for the new-gen 350s. So we’ll treat RAT000539 = RAT00539 and list it exactly for the bikes we can confirm from catalogue pages: Classic 350 Reborn (J-series, 2021-on, BS6) and Meteor 350 (Fireball, Stellar, Supernova).
This spacer goes on the disc (brake) side of the rear wheel and sets the hub at the correct distance from the swingarm and caliper bracket. If a tyre shop lost it, or someone refitted the wheel with a wrong spacer, the wheel sits off-centre and the disc can rub. Fitting the exact OEM spacer fixes the alignment because the thickness and inner bore are exactly what Royal Enfield designed for the J rear hub.

FAQs
Q1. My part says RAT00539, not RAT000539 – is this the same?
Yes, this listing is written to cover your supplied number RAT000539 and the widely shown number RAT00539/C for the same J-series disc-side spacer.
Q2. Will it fit my 2022 Classic 350 Reborn?
Yes – that’s the main confirmed model.
Q3. Will it fit Hunter 350?
NOT SURE
Q4. Why is this spacer important?
Without it the wheel won’t centre and the disc can drag on the caliper bracket.
Q5. Do I get the axle with it?
No – spacer only. Reuse your axle and nut.
