So last weekend riding 2 up my bike was just a handful wallowing all over and bottoming on things it shouldn't. Long story short ordered a new Progressive 465 shock with the remote adjust. Awesome simply awesome! Still need to fine tune it a little more but wow what a difference. Firmed up the rear through the corners and just plain keeps the rear planted on a hard launch. Only drawback is now I cant wait to do the front fork springs and tighten the whole bike up. If your thinking about a new shock this is definitely worth the money. The adjustment know is very convenient no tool required to soften or firm up the ride, or adjust for 2 up and loads.
