Henry... I am throwing this opinion out there based on nothing but my
concept of how to go fast and try and be semi reliable....
I went to the Website and checked out the front end.... try as I might I
couldn't see how the steering was applied to the front end.... nor could I
see the real benefits from it over a simple triple clamp/ conventional Folk
arrangement....
I guess what I am trying to say is could you enlighten me as to the
advantages of a system this complicated....
