First things first: At 5' 7" I am short. While the Versys isn't the tallest bike out there, it's still tall enough that I'm far from having flat feet at a stop. I usually put down my left foot and keep the right on the brake. Backing up is sometimes a chore since I can't get a lot of traction with both feet on tip-toes. I've had the seat worked on to lower it a bit, but I was still far from having my feet flat. (I have flat feet at a stop with my ST, for whatever that's worth.)
Anyway, after four years I decided to try Speedy's suspension lowering kit and today I took my V for a ride for the first time since installing the link in the back and lowering the bottom triple tree in the front. I rode about 25 miles on some windy back roads close to home, roads I know well. Yes, my feet now touch the ground flat on both sides, but I was also surprised at the improvement in the rear suspension. I know I'm not the only one who finds the stock Versys rear end oversprung, and it's probably worse for me than for others because I'm not much over 140lbs. The bikes rear spring preload is set full soft and at times, especially on less-than-perfect pavement, it's still too harsh. Speedy's link moves the aft end of the spring father back which reduces the preload at bit. (EDIT: Apparently this is not the case...see explanations below.)
Whatever the cause, the result is that the rear suspension works better for me. It's less harsh and more supple, and I'm loving it. The bike's center of gravity is also noticeably lower. The bike falls into turns with more linearity and less tippy flop-over. Reminds me of my friend's SV650 in that regard.
So overall, in addition to the fact that my feet now reach the ground (both feet, flat on the ground) the rear end doesn't feel over-sprung anymore and handling is noticeably better. I intended to improve one issue and came away improving two.
