I just read and commented on JF Coastal's post about his crash and resulting road rash. Now this! What's next?! Cormanus is going to stub his toe on his center stand?? I've got to find a safer hobby!
I also know someone who lost part of a finger this way. You're lucky, it only takes an instant to crush a finger with that size chain and the weight of the rear wheel, even hand-turning it.
Some blokes think they can save time by putting it in gear on the mainstand and idling it in first gear. Not a good plan.
