I just got back from DeRisi racing where we were testing his pro millinium revalve kit for the YFZ. All I can say is they rock!!!!!!!!!!!!!!!!!!!!!! I have been racing for several years now and can truthfully say that I have never riddin on shocks that felt this good. Yes I have ridded several of the top brand. With the kit you get all new springs which makes the front dual rates. The shock pistons are all new. These shocks lower the quad and feel amazing going over all the rough stuff with great bottoming resistance. i am race a national this weekend and will be sure to let everyone know how they feel through a whole 2+ hour race. My bet is Great!!!!!! For more info on the shocks go to www.derisiracing.com
