I became the owner of 2018 900GT a month ago. Really enjoying it, having upgraded from the 2007 versys 650.
Like a few people have said the seat is one of the worst things. The versys was very comfortable so it was a shock to the backside. I bought an Oxford air seat which makes a difference. The menu wheel is very sticky for me, but don't use it that much. My biggest problem at the moment is the front brake stop switch, I know there was a recall on these in US, but as this is a second hand bike in UK I couldn't find anything, so I bought a replacement assembly but can't find any videos on replacement. Looks easy but I can't trace the connection, any ideas?
