This is the factory chain for the 650 twin: RAT00058/A – CHAIN, DRIVE (525, 99 LINK) DID. Multiple trusted dealer/European RE parts sites list this exact number for Interceptor 650 and Continental GT 650 and describe it as the same DID chain the bike leaves the factory with. That gives us two+ independent confirmations, so we will keep fitment strictly to the 648cc twins to avoid returns. 

It’s an O-ring DID 525 chain with 99 links and is supplied as an open chain with soft/rivet link (as per export description) so you can loop it through the swingarm easily and then close it. Because it’s OEM length, you don’t have to cut links or move the wheel all the way forward — it matches the stock sprocket combo on the 650 twins. Use it whenever the original chain is stretched, seized O-rings, or you’re doing a full drivetrain refresh with new sprockets.

Key Features

  • Genuine Royal Enfield / DID chain – 525 pitch, 99 links.

  • Supplied as open chain with soft link for easy fitment.

FAQs

Q1. Is this the same chain my Interceptor came with?
Yes — sites in UK/EU call RAT00058/A “original equipment on the Royal Enfield Interceptor 650 Twin 2019 on.” 

Q2. How many links?
99 links – fixed. Don’t shorten unless you’ve changed sprocket sizes. 

Q3. Does it come endless or open?
Export description says “open chain for am / soft link with O-rings,” i.e. open with connector. 

Q4. Can I use it on my Continental GT 650 BS6?
Yes – catalogues for Euro IV/UK GT 650 list the same number; BS6 bikes keep the 525 setup.

Q5. Do I need to change sprockets at the same time?
Recommended — new chain on worn sprockets wears faster. Sell as a drivetrain kit on underthehood.co.in.
