Only problem I had was clearance of the near side pipework for the 50mm cans when fitting but a minute with the grinder and a black touch up stick sorted that.
I had mine rear facing when we came over to yours and only problem was keeping the front wheel down.
Excellent piece of kit and it did not leak even when I went to Hollland in the P******g rain for a week, best luggage I have tried on the Duke as with the proper use of Duct tape, as mentioned by Anthonye, you dont get no scratches.
Also check the clearance between the bottom of the seat unit and L brackets you need to fit, might be worth extra tape here too????
See you when you get over here
