I have a very Nice Nomad Rider Versys Rear Rack for a Kawasaki Versys 2010 – 2014
This is the original version, which I drilled some holes to fit my bag. Now they have the updated version, which has a lot more holes, but IMO is less durable as it has less solid mass.
This is made of aluminum, very solid and durable. I went with a different system and no longer have use for it. https://www.adv-gear.com/racks-luggage-systems/versys/
