On my first Alaska Highway adventure we stopped for a coffee at the Continental Divide cafe, then after taking some pictures I got on (Bandit 1200S) to ride away. I released the clutch, just got my feet on the 'pegs - BAM! I'm lying on the pavement under the bike...! WTF!!!
All we could figure is (we'd parked on the ONLY concrete around, and it was where the gas truck off-loads the gas thru those round metal-lidded holes) that as my front wheel started onto the far lip of the lid, it "kicked-up" jamming into my header and stopping me IMMEDIATELY.
There was a pretty good dent across 3 of the 4 pipes.
