593236/A – Rear Chain, 102 Pitches, O-Ring Type for Classic 350 UCE, Classic 500 EFI, Bullet 350 UCE (Standard), Bullet 500 Euro 4, Electra 350 UCE – Genuine Royal Enfield

This is the fiche-listed, factory-spec Royal Enfield 593236/A – CHAIN REAR (102 PITCHES, O-RING TYPE). It’s the same length and spec as supplied on many UCE singles that use a 102-link sealed (O-ring) final drive chain — notably Classic 350 UCE, Classic 500 EFI, Bullet Standard 350 UCE, Bullet 500 Euro 4, and Electra 350 UCE. Because it’s OEM, you get the correct 102 pitches, correct roller width, and RE’s matched O-ring sealing so it fits straight onto the stock front and rear sprockets without cutting or adding links. 

Use this when your chain has tight spots, rusted O-rings, excessive stretch or side play. A genuine chain will run quieter, fling less lube, and last longer than many non-OE 428/530 “close” chains because it’s built to the RE sprocket line-up. For best results, install with healthy sprockets and set chain slack per the workshop manual. We’re listing only the confirmed 102-pitch UCE models below to keep returns low.

FAQs

Q1. Is this 102 links or 100 links?
This part is explicitly 102 pitches/links. Do not shorten unless your model calls for a shorter chain.

Q2. Will it fit Thunderbird 350/500?
Not fiche-confirmed in the sources we checked — many TBs run different rear sprocket/chain combos. Check your VIN/fiches first.

Q3. Do I have to change sprockets too?
If sprockets are worn or hooked, yes — a new chain on bad sprockets will wear out fast.

Q4. Is this sealed?
Yes, it’s the O-ring type listed by RE. Keep it clean and lubricated and don’t use gasoline/harsh solvents on the O-rings. 

Q5. Does it come with a master/link clip?
Supplied as per OE packaging; most RE 102-link chains are continuous. If you need an open/clip style, specify at order time.
