With racetech I get answers between 6,211 and 6,405 e.g the closest would be the 6,3 kg/mm spring.
What worries me is the fact that the rates change a lot when playing with the "skill level".
Apparently they factor in speed a lot and deviate lightheartedly from the ubiquitious rule of "empty sag 30mm / loaded sag 100mm".
However, where I ride offroad, there is no speed at all, except when you fall down into a rocky ravine or off a fallen log, that one failed to climb over.
I know a WR450F is the wrong bike for that kind of trail riding but in between trail rides I do backcountry mountain roads, almost permanently banked at 45°, where on a 450 you only rarely have to shift
Having competed many years in the Austrian Enduro Championship a decade ago, but nowadays riding only rocky single track trails in the woods I'm concerned, that the race-tech calculator primarily suits the "let's do WFO" type of racer and not the rock hoppers.
I'd like to
- run near to zero spring preload (to prevent the ugly feeling of the rear hitting end of travel whengetting airborne or doing nose wheelies)
- have a loaded sag (bkie + me) of 100mm (1/3 of rear wheel suspension travel)
Anyone out there @250 lbs and 100mm "race" sag w/o preload? What rate would that be?
