Yeah I looked at the Corbin one they make for the Touring, I thought it looked good and I would make my own brackets to suit my Std but price was a bit if'y and then I came across a MBK (subsidiary of Givi) box meant as an Yamaha option it had Yamaha and MBK badges in side, I found it at a Richards place of work "Joes Motorcycles" who is a Yamaha dealer it had a remove able skin so was easy to to paint and has a rear facing reflector that is made so a LED strip easily sticks in on its backing to use as an additional Brake light, it hold a XL full face helmet with ease but probably not quite big enough for two. I mounted a Classic sissy bar pad to the top box by cutting a piece of marine ply to size a of the correct thickness to fill the recess in the back of the pad.
