I'm on 3400mls on my Stelvio now. The gearbox has loosened up nicely, it still clunks a little into first but nothing like it did. Otherwise the gearbox is very nice. It's a quicker bike than it appears, I often glance down and think 'whoops' A couple of slight niggles. One of the screen adjuster pivot pins went AWOL, soon replaced. I discovered a slight oil leak at the bottom of the engine gearbox mating. There was an 8mm bolt missing. I suspect it had never been put in. I had a suitable bolt which I put in and have had no problem since. I have spent ages messing with the suspension. I have also dropped the triple tree one ring down the forks. The suspension now feels OK but I'll still swap it when anything suitable is available. Overall it's a great bike and I'm still loving it.
Is it a better bike than the V85? I would say on the whole 'yes' but the V85 is still a better bike on the tight gnarly back roads. I made a mistake swapping the V85 for a V7 but it's going back and a V85 is on it's way...
