To protect the rear, the footpeg sliders from the 790 Duke fits just fine, and provide a sacrificial bit of nylon instead of the expensive aluminium piece. Get yourself some piece of mind for cheap (P/N61303946044, $13). Thanks Orfeas for the find!
Alternatively, if you have access to a 3D printer, advrider inmate Marchyman made a model to do the same part.
There is an option to beef up the existing front end of the bike (lights, instrument cluster, GPS): everything is hold in place by four screws and the lower metallic support. There are some (very rare!) case of the posts on the frame breaking away during a fall.
TripleClampMoto developed a contraption to add more support to the front end posts on the frame (Price is moving often. I’ve seen as low as €62, and as high as €100. Check the site). In stainless, either just brushed or powder coated.
Camel ADV has a similar part as well ($80). In silver of black. Stainless powder coated.
And Rottweiler joined the fray with their own interpretation of the same device ($80): This one only braces the top mounts (as the bottom ones sees compression instead of forward tension for the top one?). They claim it’s a better design than a piece of sheet metal.
Annnd another one, this one from Spain. In orange or black, to color coordinate with the frame of the S or the R… Very simple and the cheapest of the lot, at €55.
