Have you ever heard of "Yellow Wolf"?
Been to the Dragon quite a few times on different bikes. I cannot wait to get the B in the twisties. However, even the GL1800--extra weight, trunk and all-- has no problem hangin with the sportbikes. I read somewhere that YW's best time was about 11 minutes on the dragon, which avgs about 60MPH. I also understand a lot of that is the rider. BTW--I also read he had a tumble there and is not as frequent a visitor since then. Ride safe.
