Was on a group ride earlier this morning. Pulled up at an intersection and one of the other riders in the group thought I was going to continue and so accelerated and hit the side of the bike doing some damage to the pillion peg and sub-frame. Stupid question here: They are going to go through their insurance, so do I need to notify my insurer of the accident? When a similar thing happened with my car (not at fault, other party went through their insurer), I contacted my insurer and they weren't interested as it was going through the other party's insurance. Cheers all.
