You obviously aren't old enough to have driven on concrete X's...
No I haven't, mainly on cars.
Nowadays there are some good brands for cars and having only had a Vstrom from 2003-2009 for purely commuting, anything that last was what i had.
I'm trying to remember what i tried on the Hayabusa, the standard tyres were very good although once the the front tyre started to saw tooth the handling got very squirmy and it took a lot wrestling to get it round a corner, but that was 17 years ago.
Now the K with a massive 2000 miles on it, will probably still have the moulding hairs on it still (well except the middle 2 inches)
