Found out exactly how heavy my bike was last week when it fell over and I had to lift it up, wasn't made any easier as I had park it on uneven ground to drop a key back, must have been because I left it running it vibrated that last bit and gravity won.
It was made more awkward as I had to hold the front brake on as I lifted it.... DOH!
wrist still hurts, and I had to rest it on my knee so I could change my grip, got a nice frame shaped bruise. Was still better than knocking on doors to ask for help though...
