Yeah, that one is plenty wide.
My thought for storing mine... at least... the bikes with saddlebags... would be a wheel tray with front chock, and arms like this, but a pair in the rear too, with same width as bags, so as to give wide stance, but not exceed width of bags... and the aforementioned arms that lock onto swingarm, so it's got a good firm grip at both ends.
There's only two things we can really, really depend on in life: Gravity, and Triangles. Cats not so much, but gravity, and triangles.
When supporting anything, it's important to realize that tipover is a function of gravity and triangles. The center of gravity determines the peak of the triangle, and the outermost support point on each side determines the bottom corners of the triangle.
The steeper the sides of the triangle are, the more likely it'll tip over. Keeping the sides of the triangle symmetrical give you the best support. Keeping the sides of the triangle low (or the base wide) do same. If I'm gonna roll the whole thing sideways, I want a good solid-wheel caster, on a smooth floor, beneath a high-quality triangle. :rocks:

We fight gravity with triangles... it's an endless epic battle of forces. Always keep a few extra triangles on hand... when nothing else will do, a triangle solves all problems. Do YOU have your Concealed-Carry-Triangle permit? Take the test, get yours today, and have some Pi!
