Hi, we met at Ladybower when I was riding my NC700X.
I have R&G crash bungs on my CT. You can see them in some of the pictures in my gallery. I was under the impression that they're an 'either/or' item. As crash bars were £200 I went for the bungs at £79 instead.
I can also testify that they do work (to a certain extent). My bike slid about 60ft down the road on its left hand side whilst I was bouncing along a nice soft grass verge. Bent bars, snapped footpeg, bent gear lever and scrapes to grab rail and shaft drive housing but no damage to panels or engine casings. Again there are a couple of pics in my gallery.
