I spec'd my bike with the 85-90kg setup, which has 5.0N fork springs (0.51kg/mm) and 58N shock spring (5.9kg/mm). Initially the forks felt great but after break-in they softened up quite a bit and now the bike is a bit on the soft side for my preference, riding pure motocross. Not surprised that RaceTech specs .53kg/mm fork springs and a 6.1kg/mm shock for the same weight. Thinking i'll be going up a rate front and rear here pretty soon as i start riding more often again and get my speed back up to par.
