If you can find the parts cheap, or at all, it may work well for you. However, you have to consider thats about $200-$300 that could be spent towards a nice set of Ohlins. I personally would not recommend Progressives. They are a decent shock and improve handling, but I don't think they improve the comfort of the ride much, and have pretty harsh rebound damping, that cannot be adjusted.

My first recommendation is to ride the bike as is for a thousand miles, let the shocks break in a bit, and experiment with air pressure. (a pound or two plus or minus can really change the ride) The 09-10 SG shocks are a LOT better than 08-older versions.

Ride the bike and play with it a bit before you spend money fixing a problem you may find you don't have.
