I purchased a set of ALT Rider Engine Guards for my 2013 F 800GS.
Their bars seemed to be the best coverage out of one bar with out a bunch of add ons. The fit and finish is extremely clean, the front connecting area uses a billet alum insert for solid reinforcement, and the upper mounting uses the original engine mounting bolts with a full length portion of the bars inserting into the frame recession.
Expensive, but great fit and finish, easy to install, look great, and all though I have not had to put them to the test they look to be built to handle multiple crashes if need be!
I would attach pics however im new here, and still have not figured that part out yet?
