I bought my Thruxton R new in Jume 2016 and still have it. For longer all day rides I use a Corbin seat. I've occasionally drag and done land speed racing both in stock and slightly modified for over six years with no mechanical problems. The motor will run varies gear combinations with no complaints. I've run tall gearing a got 151.3 mph and 11.6 ETs in the quarter mile with stock gearing.
Good review and great to hear the excitement when hitting the gas! Got the same bike at home and absolutely love it. True about the longer rides though, I ride about 1,5 hrs straight, but a whole day of touring will be tiresome
