2 European tours and 10,000+ miles later the bike still impresses every time out.
stewartswan there is certainly some backlash in the drivetrain, especially the pre-2013 models, but I find it's not so bad with a few more revs. Being a 6 it's easy to ride at l,000-1,500 rpm, which is great on a steady throttle but can be less smooth on/off the throttle. The gear change also improves a lot with a few more revs.
Off to the alps again later this year, the bike is just wonderful, solo or two up with luggage it stops, goes and handles brilliantly. Not that it's significant once you've blown £19k on a bike but it averages around 50MPG and the original rear Z8 Interact was still well legal at 6,500 miles, looks like the PR3s will last longer. Probably 90% 2 up riding so I can't rag it too much, but we "make progress" as the Police might say.
