Here is my short take on the new chassis ...
When HD was developing the Vrod they encountered extreme torsional problems with their prototype welded frames. A traditional frame could not take the stress that the new Revolution water cooled power plant subjected them to. Harley hired a company that specialized in water extruded frame construction to eliminate welds and provide a stronger frame. Harley was so impressed with the company that they ended up buying them. The touring chassis that has been in use forever on Harley FLs flexes something terrible. Many of us who ride FLs have experienced speed wobbles, rear steer, head shake, buffeting, you name it on these bikes. The rear swingarm has been especially problematic from a handling perspective. If you disassemble one you will find the swing arm pivot uses self centering bearings, which allow the swingarm to move in the horizontal plane as well as the intended vertical plane. This is the primary cause of the dreaded rear steer effect, which usually happens when banking a corner at high speed. The key changes to the new chassis appear to be a redesigned and stiffer rear swingarm, a new mounting point for the swingarm that is closer to the vehicles center of gravity and a new frame which appears to have less welds. The new frame also weigh substantially more - 35 pounds according to the Moco. We all know the 2012 emissions standards are looming large and that it is highly unlikely the air cooled Twin Cams will qualify. Therefore I am speculating that new touring chassis is the first step towards building a new frame/platform that can handle a higher powered, more efficient, cleaner, water cooled engine in the next two to three years. We will probably see the bugs worked out of the new chassis for 2009, 2010 and maybe even 2011 before Harley drops a water head in this new frame. Just an educated guess on my part. ![]() SM |

I hear they are also adding an EG Ultra Trike to their lineup. Have you heard anything about that?

Call me a Guinea Pig for the MoCo, but I've got a 2009 Street Glide in the garage.
I've got 600 miles on her and of course, she feels great. I suppose I'll know more about the machine the more miles I put on it. |
