Well, I've got the wheel rates listed in the spec sheet I have, so it should be simple to calc the motion ratios.

Front Spring rate = 20 N/mm
Front Wheel rate = 18.8 N/mm

Front motion ratio = FWR/FSR = 0.94


Rear Spring rate = 16 N/mm
Rear Wheel rate = 15 N/mm

Rear motion ratio = RWR/RSR = 0.9375
