CK,
When I talked to Wil Phillips, the inventor of True-Track, at Sturgis he made a few interesting points:
1. The MOCO will never admit the problem exists because of all the past Instability Lawsuits they've fought and won. Or settled out of court. Therefore they won't be making any drastic structural changes to eliminate the problem either since it would be addressing a non-existant problem as they previously have claimed.
2. Wil has also been used as an expert witness against the MOCO multiple times for crashes resulting from instability issue's which are litigated around the country.
3. Wil claims a wobble or bike instability action can occur at any speed....slow or fast....its the manuver, twisting, flexing etc which initiates the instability not necessarily the speed.
4. Wil claims Road Kings and Screaming Eagle bike's are the most likely to have issue's because of their geometries. A lowered bike changes the swing arm's angle which increase's the potential for a problem to arise.
Feel free to call him directly, he's very passionate about this problem and his solution. Refer to my post on Page 5 of this discussion for all his contact information.
Good Luck.
