Parked my bike on Hill St, North Sydney at 9.00am today in the designated motorcycle parking area. It's on pavement for those that don't know, at the top of a hill with space for about 15 bikes and one car space with a chain across in front of the parked car. Anyway, parked up in a space and had a channel available both in and out of the area. Came back after half an hour and found I was blocked in by a Kymco scooter in front and a Vespa behind with some Honda scooter pretending to be a bike behind that. All the bikes around me had steering locks on which p#ssed me off no end as it limited any ability to get out. So I wait 30 minutes and it's clear I could be there all day. I'm self employed so I can't afford to wait any more. Take the Kymco of the center stand in front of me, wheel it round as much as I can and put it back on the stand. I then thread my bike through the gap between a Ducati Monster on my right and the car on my left then out the space where the scooter was. At that point I just clipped the rear wheel of the scooter and being high and light it went straight on its side. I nearly dropped my CB600F trying to stop it falling (no chance), so got mine out of the way, went back and inspected the damage - bent rear brake lever and scuffs to the top box. Picked it up, put it back and left a note with contact details on. So angry though - both with myself and inconsiderate riders boxing everyone in and leaving locks on. Is there some etiquette there I'm missing in these areas???
