The published pictures of the naked frame with the shock gave me an idea. The amount of shock deflection for a given amount of swingarm travel is dependent on exactly where the shock is attached to the swingarm and the frame. Mounting the shock at a different point would have the same effect is changing the spring rate, preload and damping of the original shock.

Shocks have adjustable preload and damping, but not spring rates. It seems that by simply providing an alternate attachment point for the shock, the effective spring rate could be changed, allowing a better fit for riders of varying weights. Was this considered?

Good Point Jim.

Variable mounting points were used over seventy years ago on the venerable Velocette.

Erik would know about that, he used to have one.

So did I as a matter of fact. Nice bike.

It's better to get different springs of course... but I assume you know that. It's not that difficult to change springs either.

Also... If you have a good damping setup you would only want to change the spring... Not all three. That's improper form.

I would rather have a few extra holes/tabs on the frame than more "alternate parts" hanging on the garage wall. I'm not a very heavy build and when I had an '87 Heritage Softail I just ran the tires a bit low to add some cush. Not something, BTW, I'd recommend on any Buell.
