I was coming home from the shop where they installed my new chain kit. I was splitting the fast lane behind another bike. Halfway home, eastbound on the 10, another bike gets on at La Brea. He finds a gap and shoots over to our lane, not even checking for bikes. He cuts off the bike I was tailing. We brake in time and are fine. Then, the bike I was following goes to the number 2 lane, and splits the 2 and 3 lanes. I decide to do the same, because the bike that cut us off sucks at lane splitting, he is constantly slowing down and coming to a full stop in between cars. I move to the number 2 lane. Im at the right line of the no.2, and i turn my head to make sure no bikes are coming and that my path is clear, as soon as I turn my head back, I see the lights on a Civic light up. I try and lean over to the right to avoid it, but Im too close and end up clipping his rear bumper. I dont remember going down. my bike needs a new headlight housing and the front fairing cracked. me and the civic exchanged info, CHP took our report, no citations issued. I rode the bike home. Sorry this is so long.
