Hi - I thought I recognised the name from the Versys forum! I did have a Nitron shock with uprated spring fitted to my Versys, and although it solved the problem of the excessive rear sag, it didn't fix the low speed handling. It seemed to be to do with weight distribution, but only a few other people had the problem, so it was a bit of a mystery.
Anyway, the GS TE with auto preload and dynamic ESA completely eliminates this sort of issue for me, and the handling two-up with luggage is hardly any different to riding solo, which is testament to the effectiveness of the system, and all without any tedious manual tweaking of suspension settings every time you change from solo to two-up.
Hi, Yes I still have my Versys but do love my GSA especially the suspension and handling. No faffing twiddling preload and such.........
