8/12/2019 Ktm With A 116 Link Chain What Gearing
Jun 15, 2011 I have 16/42 with a 116 link chain and there is plenty of adjustment left. Thats on a normal Duke 690 though. BTW with regards to the front sprocket or rear sporket changing, it doesn't really matter which one you change it's all about the ratio. I recently changed my sprockets and chain, bought a 120 links chain but it was too long so i took away to links. 118 Links was still to long, took away 4 links, now fits perfectly. I like a short wheelbase on my bike, i can guarantee that 116 link will work as well with stock gearing.
I am replacing the chain on my road bike soon. How do I know how many links to get? Does it have to exactly 114 or 116. Or is it not a big deal?
I ordered a 116 link chain. Will I need to shorten it?
Thank you.

If your old chain was 114 links (assuming it was the right size to begin with) then it's a good idea to take a couple of links out of it. It'll still work with two extra links but shifting may not be optimal and the chain will fall off more easily. Keep in mind that one chain link is composed of an inner and outer link, so a link is actually two pieces with a hinge in the center. This means that to remove two links, you'll actually remove four pieces of chain with three hinge points.
If the old chain was 116 links and you're trying to replace it with a 114 link chain, you'll run into problems. A chain that is too short can jam when shifting and puts puts too much strain on your rear derailleur.
To determine the correct length, wrap your chain around largest chain ring in the front and the largest rear sprocket, without running it through the derailleurs. Make sure that the chain is long enough for one full link (again, inner and outer) to overlap and you'll probably be spot on.

A standard replacement chain is always several inches longer than needed for a standard non-recumbent, non-tandem bike. What I generally do is hang both from a wire and match up the links (the old chain will be 'stretched', so you can't simply match by length). Then I 'break' the new chain at the location (number of links) that matches the old.
Skilled mechanics can simply stretch the chain around the big rings front and rear, put their finger on the link that meets the other end, and break it there, but I'd rather be sure that my new chain matches the old exactly (if the old performed well).
