Chain Sizes - 2016 W/c Street Twin

Hi all,

Has anyone out there in the ether put a 525 chain on a 2016-18 model Street Twin? I've been looking at options of lengthening the gear ratios as I've got a chain and sprocket replacement coming up so have the opportunity to give it a go. I run in 5th gear for most of my commute and adding a taller 5th gear makes life much more comfortable, so I've read on another Triumph Rat forum (link below - beware it gets nerdy!)

Having spent time on the phone with JT Sprockets, the dimensions of the sprockets used on the 1200 Thruxton/T120 models are the same, but with a 525 pitch chain as opposed to a 520.

The additional width which comes with the 525 is where the main question marks sit for me - will it work?
