I've been drooling over that smoking hot K1600. Those guys replace the stock shocks in 20 or 30k. Your stock rear suspension isn't the way it used to be after 40k miles. You might see noticeable improvement by just renewing stock. You don't notice it as it slowly degrades.
I changed my 1500 to Progressive last year, seems OK. I can't see spending thousands on a touring bike suspension. It ain't moto GP.
