No split link on these, it would be suicide imo
Jt sprockets and a dud chain off eBay seems good value, with a chain tool to rivet the thing
As for your linkage, I did the s1000rr shock, easy mod, I used an early shock, bronze body 2008 iirc. This has transformed it, and the rear is an inch higher. I’m on tiptoes but I love it !
