I'm sorry you wrecked your bike and I'm glad you made it out of the accident unhurt. Everyone on the ride was probably hitting corners aggressively yet everyone was getting different results mostly due to their experience and skill set. I am not trying to make the point that aggressive is bad because in my opinion that's what makes riding fun. You were trying to ride beyond your skills and you had all the warning signs to slow down before something happened yet you chose to ignore them because you were probably trying to chase faster guys. I get that this happens in group rides but it is your responsibility to ride your own ride within your means. As soon as you went off the road or touched the yellow line you should have went back in the line a spot or two and learned something, not gone around people to go faster. The guys in front of you weren't pulling away because they were going really fast in the straights it was because they could judge entry speeds and handle curves better. None of them started riding like that it was learned and practiced. It was foolish of you to try to chase these people when you had warnings. When learning a new technique sometimes you have to slow down to perfect it and the speed just comes with it later. Because you were being selfish and thought you needed to keep up with the faster guys you changed the ride for the rest of the group. That was my point. Nothing serious happened and hopefully someone else reading this will learn something or think about their actions on the next group ride.
