I believe they are 65mm ID 7" and 9" springs. 450 and 800lb/in
My wifes Ohlins RT had an issue where they updated the internal piston and the tolerance was just large enough to cause clunking noises over slow bumps. Ultimately they had to rebuild the front dampers to resolve that. Not sure if it is related to this but certainly a possibility.
