A lot of good and fair comment in the video.
Correct me if I'm wrong but isn't the front suspension on the Slingshot more or less fully adjustable? If you know what you are doing you should be able to get it to steer pretty much how you want, or as is more common with adjustable suspension you can turn a benign, good handling machine into a completely evil widow maker in just a few minutes! Adjustability can be a double edged sword.
I'm not convinced the spend as much as possible approach to customising the M3W adds to it at all. (Add in usual "each to their own" comment here)
