I believe ST1100's were the best bike ever created. I sold BMWs and Triumphs and told this to anyone who was shopping for a BMW and asked what I thought was the best bike made. I've owned 3 and put on about 130K on them. Also owned three R1200 GSA's (2007,2012, and currently a 2016), to the tune of 145K miles. In between owned some of the GSA's and an RT I tried an africa twin DCT, TIger 800, and the 2009 R1200RT for about 20K. The RT did everything the ST1100's did but simply felt more refined. I only sold it due to hand arthritis and wanting the trick buttery suspension on the 2016 GSA. Never had a serious failure with any of my 73 bikes over the years. RTs can have problems though, like any bike. The shaft service bulletin on all wetheads from 2014-2018 did not inspire confidence either. I service my bikes myself and am anal about doing stuff well ahead of schedule. A newer wethead RT would be a phenomenal improvement suspension wise over any ST11 or 13 for sure. Cruise control is great to have as well, and weather protection is second to none. I still look at every ST 1100 that pops up though, as they are very smooth and I love them still. ST1300's are really nice once rolling but heaven forbid you get caught pushing one around because they are the second most top heavy feeling bike I know, the old K1200LT's being the all time winner.
