I have fitted a pair of these. Untried with a pillion, yet.
The pegs themselves are light and well made, IMO. The kit is bolt on for the 650, but weld-on for the 400 and 600 (IIRR re the 600). I have the 400. Points to consider: is it illegal to put pillions on your crosser in your country? It is in the UK, but then the bike won't be used there.
Also, the welding plate that the pegs bolt onto is not very well thought through. The plate was not pre-threaded, and the plate was WAY too small to weld on easily and left your pillion with knees just under the ears. I had to get trapezium shaped plates made up by an engineering workshop, which gave us a far longer welding length and brought the pegs back and down: far better.
All-in-all, a tidy set of pegs, but just be prepared to fettle a bit, IMO so, for me, this brought down the value overall...
Adventure: it's an experience, not a style!
(so ride what you like, but ride it somewhere new!)
