I just put in a set of Viper ER shocks in my 01 700 SXR. Only ridden it once, but it seemed real nice. Definately a little softer than the stock sxr setup. As far as spacers and setup, I left everything the way it was on the stock sxr setup, except for a Maxx Performance W arm, as my stock one was cracked. Limiter straps and transfer rods (I have Bender TS3's) are set as they were for the sxr setup. Again, only one ride, but definately more compliant over the rough stuff. I also have a pair of Ohlins piggybacks up front......I think I may set the rear shock up a little stiffer as I now am riding the FRA in the stiff position because the middle position seemed a little soft, so I will screw it in a little to get me back to the middle FRA...
