When I had Kyle rework my forks (as in re-valve and re-spring), they came back with Ohlins springs and valves.
Because the valves were replaced, the OEM oil lock pieces on the forks were removed on the cartridge damper rods.
The Ohlins springs used for my forks were 04745-11.
The Ohlins 04745 springs are 27mm I.D. x 37mm O.D. x 240mm length.
They were used with the OEM fork spacer.
Ohlins measures their spring rates in N/mm.
The more popular springs used for SP2's are:
04745-95 = 9.5 N/mm = .96 Kg/mm
04745-10 = 10 N/mm = 1.02 Kg/mm
04745-11 = 11 N/mm = 1.12 Kg/mm
