A long time friend is hard to lose, like losing a family member and all of us experience riders know that a moments lack of 100% concentration can end our ride, we all enjoy riding on two wheel but its still hard when we lose someone we have known a long time. My condolences on your loss, keep in mine though that he was doing something he loved, I have always told my family that, if my life ends riding a motorcycle I was doing something I loved and enjoyed.
