I have this:
Crash frames Kawasaki Versys 650 2015-2021, Kawasaki VERSYS 650 2015-, Crash frames RDmoto, RDMOTO
www.rdmoto.eu
For North America only 1 dealer in Canada, and who know how much cost.
Didn't test them, but I think that everything will be untouched except steel on crash bar.
Connected on 3 points to motorbike on each side, and they are connected together in front of radiator (4-th point).
I know to relax my foot on them on highway (place where middle part are connected with lower part)
Extra vibration after instaling that crash bar ,or it was in my mind only because I only have that motorbike 2 months when I buy crash bar, and I was still learning to ride (my first motorbike ever).
All in all i am happy with them, and It look nice on motorbike.
