Got round to fitting the R&G tail tidy yesterday, my advice would be to spend a little more and go with the Evotech. Don't get me wrong, the R&G is a vast improvement on the stock kit and looks good, but the Evotech (from the photo's I've seen) looks much better on the bike, and is apparently easier to fit. I went for the R&G as I've used their kit on most of my previous bikes and it's good stuff, plus I've got other R&G parts on my 899 so wander consistency.
It took me around 2 hours to fit, but that included tool finding time in the garage which is currently full of boxes and other shite destined for the dump! Eventually found my crimping tool for the plate line wires.....
Utilised the reflector plate from the stock unit, fixed to the rear of my new plate so as still got a rear (tri colour) reflector, IMO looks good. Will get some photos up if it ever stops raining!!!!
