OE tyres are rubbish on the 1000. Had the 650 Mon\Tues, exact same rubbish experience. I ditched those OE tyres after 4K miles because the ABS kept cutting in, even in a straight line FFS. Road 5 haven't caused the ABS to kick in once, but the Road 5 is not the greatest lane scratcher as those side wall sipes make for a very nervous grip when pushing the limit, it feels like the front end will slip when pushed hard, and you can see why if look at how the edge goes rubber, gap, rubber, gap etc. Good touring tyre though, and wet weather is superb. Will change to ME1 at the next change as I want a consistent tread pattern.
Very little adjustment to the chain (yay Scotoiler) after 7500, but yes, it is weedy, will put something better on when that day arrives.
MRA screen on the standard screen is a really good solution, super stable, if you are 6ft or less.
