rear Shocks have been changed to to RFY by previous owner due to mot failure originals where leaking.
Any experience with these they sound like nasty cheepo,s
A quick search on ‘rfy shocks reviews’ says definitely stay away from them. Broken mounts, sagging springs, leaking seals, very short life. You get what you pay for.
Previous owner put them on 
That’s another thing added to the list of future projects .
I’ve research rfy you can get them for as little as £120 they were a cheap fix.
Pin to pin on my v7 111 2017 on rear shocks read 330mm, if correct shock size should be standard 350mm so assume they are 340mm silver rfy shocks.
Their time is limited and on the list of to does.
As I’m use to more leg room (29/30 legs) would a true 350 mm or 360mm shocks help.
Hi, suggestion - speak with Hagon. In context, my 2019 Mkiii Stone was retrofitted with Hagon shock absorbers and progressive fork springs which transformed the handling; lastly balanced BT 46 tyres are worth considering
