There are a few good shocks around, but of course the good ones do cost that extra, I brought my Koni's way back in 79 and they are still good even after the first rebuild 11 years ago, I also ran a set of Ikon's on my 2013 Thruxton but because I will be selling it I took the Ikon's off and replace them with the other shocks I had, I was going to put the Ikon's on my new Thruxton but they are 25mm shorter so will be getting a new set for it the right size, I will support Ikon's as I have had such a good run with them for long life and lots of hard miles as well cheap to rebuild and was a easy job.
I am like most on here we all have our favorites brands and will stick by them, why change brands when they work so well, so having my old Koni's and have 2 sets of Ikon's for the Triumph and my Manxman project bike I will stick by them as they have already proved themselves over the years of hard riding, on my Commando/Featherbed I have my Koin's set on the first spring setting and the damper settings on 4 for hard sport riding through the tight twisties, but most would set the dampers at number 2 or 3 setting for more comfort.
I have also have pics on here when I did the rebuild of my old Koni shocks step by step rebuild, if anyone is going to do a rebuild, just have to do a search for them.
There are a lot of cheap shocks around but if you push or ride hard and want long life out of your shocks then pay the extra and buy good quality shocks, ones that can be rebuilt and they will last a life time, my old Koni's have well over 160K miles on them, so I think they have proven to me they are good shocks, the Ikon's are the same as my old Koni's in every way.
