Hi guys
I have a few questions reg the drive chain. mine broke.

*What happens to the broken chain? can it be used for spare links? Or must it be thrown away? seems such a waste as I think my broken chain is really still in very good shape. (I had to shorten to 108 in emergency.)
*Ok to use o ring links on x ring chain?
* PO installed new sprockets and chain and it has about 12000km on. chain broke but sprockets still very good. 👍👍 Should I get an expensive chain now or rather just OEM and change everything when all 3 is worn?
*Looking at DID 520vx2 Street chain. is it good for Tenere 660?

Thanx alot!
