Easy for you to say when it's not your bike.
At least 450,000-500,000 motorcycle miles under my ass (I'm an old git) and the worst mechanical failure as you put it, has been a broken rear shock dog-bone link on a Muzzy Raptor 750 with less than 2,000 miles on the clock. I wrote that off to the low production number and Rob Muzzy not minding the store. It was a Muzzy link, not Kawasaki.
I was on the fence about buying the V100, but this Welshman's experience was beyond reasonable so the V100 is off my dream-sheet.
Ironically, my consolation buy is a GSX-S1000GT as well.
Who cares?

You obviously missed that completely.
