First of all, sorry if it's the wrong forum. I debated here and the media forum but decided here since it's a newbie warning. This video is taken from my mate's GoPro. He was riding a GS500F with his girlfriend (the L plater on the 300), and her parents. Just after they took off from the servo, he went to lower his visor. In doing so he briefly obscured his vision of the bike in front of him, and as it came into view again he saw it was a little closer and panicked thinking he was going to run into the bike in front. He grabbed the front brake.. while his left hand was still on his visor. Without 2 hands to stabilise the bar, the bike dropped instantly and ploughed him into the road at 90km/h. Luckily, he walked away with just skinned shin and a skinned forearm. The bike was written off and he now rides a GSX650F. He's very lucky it didn't turn out worse. So for the love of your own damn skin: PUT YOUR VISOR DOWN BEFORE YOU MOVE! KEEP 2 HANDS ON THE BARS! It only takes a split second of inattention to go down.
