I put these on my TW200s. Work much better than the solid stalk OEMs. I can see past my shoulders. Only issue is tightening the lock nuts. I can't move the brake lever/cylinder out enough to get any wrench on the nuts.
Simple, solid, ballhead design, simply works. Tension is easily adjustable. they stay in place going down the road, but will yield to obstacles when hit in the woods. I can fold them down and back up with one hand while moving.
I liked them so well on my TW200, I put another set on my Kawasaki.
Very nice foldable mirrors for street or trail. RH mirror fits backward threads on right handlebar. A little tricky to get the angles and tightness dialed in but after that they are secure and vibration free.
