If you are in the market for a new chain or a spare its worth checking out 24MX at the moment because they have some good deals but in particular the Twenty X ring Delta available in various colours this is the orange version at £28.99 https://www.24mx.co.uk/motocross-parts/chains--sprockets_c359/chains_c362/twenty-delta-seal-520-x-ring-chain-orange_pid-PM-0083087?v=22906  I don't think you can buy an x ring chain anywhere else as cheap. If you do buy one they come with one clip type link and a rivet softlink type however buy a spare link (or two) as the pins are very slightly smaller in diameter than  say a DID chain.

The chains are in different lengths ready made to fit your machine the link is for my freeride 118 links

I bought one when they were at £42 which is still good and fitted it and was impressed it didn't need much adjustment early on and has been really good. I have now bought two more and 4 spare clip links as well just to be sure as the pins are slightly smally it will go on a DID or similar in an emergency.
