I think the only reason I didn't go down was that my rear wheel was perfectly perpendicular to the car's bumper when he hit me. Also I have clubman bars and rearsets so my weight is distributed differently than in the stock upright riding position where the impact might have caused me to flail backwards a la whiplash and pull my hands from the bars. I visited the site today and tried to reconstruct some of it in my mind and realized that we probably moved maybe 2-3 car lengths between the time he hit me and where we both came to a stop. I probably did not grab a handful of front brake which kept me rolling forward instead of tumbling over the bars or doing a backflip into his windshield.
Meanwhile, the dealer is going to cut the neck off my old frame and send it to Triumph in Georgia who will then contact the Triumph factory in the UK who will transfer my old VIN onto a new frame and ship it back to the States so I maintain matching numbers between engine and frame. Let's hope they get it right the first time
My GF and I went a little crazy and I bought the Thruxton, I'll finish cafeing the bent frame Bonnie with the fender eliminator and seat swap out during this rebuild AND this morning we bought her a 2012 Guzzi V7 Racer for Christmas (every girl needs a new tractor at least once in her life)...
So the happy ending is we both bought new bikes we don't need but can't live without and I get the chance to rebuild the Bonnie into something awesome at little or no out of pocket cost. Nobody is in a wheelchair or on crutches. Win-win almost all around!
