Not exactly.
Preload is not where you get 'stiff'. 'Stiff' can come from a number of places.....the simplest is the clickers on the bottom of your forks. Crank 'em up!! Jar yourself silly!! ;)
The stock spacer are somewhere around 90-100mm. Mine are lying in a box at home..I've measured them before, but afraid my single brain cell fergot the exact number.
re: for the 200?
You bet'cha!
By the way.....the 'outperform' statement is completely, wholly and 100% imo. I've run power, carbon, the radvalve and the DFII on the kdx and compared some sets side by side (two different similarly modified kdxs), so my imo isn't completely without basis.
Cheers!
