Sitting in the garage pondering life's problems. Things like Indian or Chinese tonight. My mind wandered to a cheap solution of how to mount handlebar mirrors to a pre-2013 RT.[/size] Looking at my other bike, a Royal Enfield Himalayan the idea hit me between the eyes.All you need to buy is an 8mm threaded rod. Most DIY shops sell there for under £6.00 for a meter length. With 4 nuts and washers to suit and a pair of handlebar mirror extenders. You can pick these up for about £11.00 on eBay.First cut the threaded rod to length. Pass this through the handlebar switch unit. Here you will find an 8mm through-hole here. With one nut(locking type) and washer attach this to one end. Thread the threaded bar through the 8mm hole and then through the mirror extender bracket. Now with another nut and washer tighten the nuts down. Do not over-tighten the bolts as you are clamping the soft ally casing. Do the same on the overside of the bars and hay presto you can now fit any mirror with the correct 8mm thread to your bars. You can fit the 10mm extenders but still, use the 8mm threaded bar. Am going to use a pair from a KTM 1290/390 adventure mirror i have in the junk box. I think these will suit the bike as there are no spindly rods showing under the rubber sleeve. Plus you can get a replacement glass for them(£6.99). The pictures below show what you need
