Just thought I'd give anyone thinking of fitting this a heads up. Just fitted mine and had several issues with it. First, the two pieces don't fit flush at the tail end, ie small gap between pieces. Had to either screw the bolt all the way in to force pieces together or fit a spacer (washer in between to fill the gap), which I did. Second, the bolts provided to secure the two pieces together have threads that are too shallow causing it to destroy the thread of the tail piece. I had to use a bolt of my own which was longer and had deeper threads to solve this problem. Finally, the unit is fitted too tightly when you fit the tail tidy to your bike causing the wires and cables to be pinched. This made it difficult to unlock the seat mechanism. I solved this by fitting spacers (washers) and used longer bolts to allow a bigger gap when fitting the tail tidy back on the bike. Maybe I don't have the skills to complete the job properly but I'm posting this for anyone thinking of or will be installing the R&G unit. I have to say it does look good on the bike!
