I've ridden a number of 1200RT's and like you Chris, the first two handled like wheelbarrows. The first one was a half-day test ride of an early one. I'd bumped into a former colleague at the dealership, so we went for a ride. I was concerned that it was me so we swapped bikes. I followed him on his Blackbird and was relieved to see him struggling to keep it out of the scenery.I shall clarify: Had a RT courtesy bike while me GS was in for a service. Loved the toys. Couldn't get away with the fairing in anything other than motorway riding.
Handling-wise, it felt at first like it didn't want to tip into a corner and then like it was going to fall over.
It gave me absolutely no confidence in the front end and I was glad to hand it back before I crashed it.
Maybe if I hadn't been riding the GS for 7 years I wouldn't have been so critical?
The next one I tried was as bad. It tipped into low speed corners and turns like a wheelbarrow with concrete blocks piled over the front wheel but at higher speeds didn't want to turn at all.
Later I tried one back-to back with a GT. This one handled like a dream. It seems that they are very easily compromised by incorrect tyre pressure and or tyre wear as those I've ridden since have all been sweet handling.
For me, I hated the 1200RT riding position, like the 1200GS, it's on rather than in (the low mirrors only seem to increase this sensation). I found that lower leg weather protection is nowhere as good as I'd expected (rather worse than my 1150GSA, I suspect that that has more to do with peg-cylinder positions as it seems to be as poor on the 1200GS).
Styling-wise, I think that the 1200RT is awful. The forward-slope of the angles give it a very nose-heavy look, almost drooping. It looks as though someone has parked it too close to a heat source and the plastics have sagged.
