Hey, I guess Im due an update. In short no. I opted for a refund. MUPO believe the "Italian version" of the SX has the BPF forks of the Z1000 for years 14-16. I really tried to work with them and sent detailed photos in the hope they would see their internals could be adapted pretty easy but they didn't want to know. I had to forward them pictures from the parts fiche to proove the forks are different! I then asked if they had anything else that would fit because they also offer 20mm piston kits and fork springs but they also turned this down and told me they don't have anything to fit my forks.
WRS, who I purchased from have been great and took over the communication. My understanding is that the MUPO factory has been hit badly by COVID so maybe this is the real cause of the issue. WRS said they will pursue options with MUPO but I cant see that happening. They refunded me on returning the Caliber22 kit as of yesterday.
Overall, Im pissed off that Im now stuck with a shock and no improved front end. In truth, I wish I had gone another route as there is better available for only a couple hundred more but I was already stretched going with the MUPO kit. The MUPO kit offered so much for the price that maybe it was too good to be true. Other vendors offer priston kits and springs that come close enough to 500€ cost of the Caliber22. So for the extra MUPO cost, you get 22mm pistons and fork caps that offer a more accurate (clickable) setting in addition to a spring for your weight. Travel would have been the same if not more as there is no hydraulic bump stop.
The GT1 shock does appear to be a big improvement over the stock that I had. Time will tell if it holds up.
