Just passed 3,500 miles on mine. That includes 3 races and a return trip to South of France from the South East of England. The only issues so far have been very minor. Tiny oil leak from oil cooler, fixed by tightening. Indicator relay stopped working, fixed by replacing with a generic 3 pin relay.
It generates a lot of interest, I've had people hanging out of car windows to take photos ( at motorway speeds!) and a big thumbs up from a Parisian Gendarme. You can also expect a lot of questions every where you stop.
