Stark Varg Fork spring 4.1 N/mm

This 4.1 N/mm spring is the main coil inside one leg of the Varg's KYB fork, carrying the bike's weight while the clickers control how fast the leg moves. It sits between the 4.0 and 4.2 rates. Fitting it means draining and refilling the leg to the correct oil level, so seals and bushes are worth inspecting while the fork is apart. Part 110054809401.
