Well, it took nearly 9 months, but I dropped the GPX for the first time this morning. Was at the Mobil on Hoddle St putting some air in the tyres. I dismounted and my backpack got caught on the air hose roller thingy. So in effect I was stuck on one leg and couldn't move due to the backpack being caught/wedged. Bike toppled over, luckily I was basically able to "guide" it down, so there is only extremely minor cosmetic damage to the right hand side on the petrol tank - right near where my knees go...so I will be able to buff it out etc.
