The FJR has plenty of lean angle, you just gotta know how to position your body. Hell, I had my FJR at the Gap running a decent clip, barely scraping and I caught a 600rr and the guy was touching knee. Other times, I've been through there putting on a spark show, dragging pegs and canyon cages, just cause I wasn't moving around on the seat. I'm not gonna buy an adventure bike to get more lean angle, that's for sure.
I've sat on a couple RTs and it does not hide it's weight well IMO.
