Over the years I've has 2 1100's, 2 1150's (inc GSA) and 2 1200's and they're all great bikes, I've just bought a MTS 1000 and find it so much more rewarding to ride.
All the GS's are nicer for a bimble but pick the pace up and it's a different game. I'm frightened to try the 1200 as I'm going to ...
