I installed a set of Nomad Rider Guards on my 2016 KLR650 yesterday.
KLR 650 Crash Bars (08-2015)
I also considered (in order of ascending price) Tusk, DirtRacks, Mastech, Givi, Hepco & Becker, SW Motech, Happy Trails and R&G. After I made my selection of the Nomads, I found that Moose Racing also offers a set of guards, but they look exactly like the Happy Trails that I’d passed on. The range of pricing was $159.99 for the Tusk up to $499.99 for the R&G. The Nomads were $243 shipped.
There are a lot of pros and cons on each option, but the one big thing about the Nomads that I wanted to show you was the amount of physical coverage compared to the other options.
Below is a photo of the Nomad and then somewhat comparable size/angle (stock) photos of the seemingly most popular Givi Guard and the SW Motech Guard (my second choice). The Nomad has much more coverage than those other options and a cross member to make up for that big ring of emptiness in the middle.
The bar diameter on the Nomads was 1 1/8 inch (28.6mm) slightly larger than the reported 27mm of the SWMotech. The metal thickness is 2.5mm. I had read some reviews about cracking welds on the Nomad that apparently were isolated to a period that the Nomad bars metal width was only 1.8mm. If that's the case then the Nomads are really the meatiest of options.
Of course that means they weigh more too. The weigh was 15 pounds. Their website said they were 10, but I weighed them on my scale at 7.5 a side.
If coverage isn't that big an issue and budget is, I'd say look at the Tusk and Mastech, $160 and $185, respectively. They both looked like a decent set up.
