Don't take it as gospel (especially since the numbers on their site have been changed), but RT's calculator says the stock .65kg/mm springs are good for 96lb on the street or 76lb for racing. The 9.3kg/mm rear is good for 210-220lb. The '06-'09 GSXR 600 spring is just a tad stiffer at 9.4kg/mm.

My weight is 175 lbs and when I go to the racetech website to calculate my spring rate it gives a 0.70 kg/mm spring for me.

The
NewGen and
300 calculators both give me .746kg/mm street and .783kg/mm race when I put in 160lb. For 175lb, I get .768 and .807.
