I own a K4 1K, and I recently came across some Ohlins fork springs for cheap to upgrade on my stock internals. The only concern that I have is that the springs are at .95 kg/mm stiffness. I weigh between 180-185 w/o gear. The majority of my riding is on the street with some track days every now and then (80/20 split). Do you guys think they would be too stiff?
