Ohlins fork springs of 80N/mm weight that came off a 2020 Ducati Supersport S. Have seen about 7000 miles of street use. Had them replaced to a higher weight spring when I had the forks serviced recently.
These can work with any bike that has the Ohlins NIX 30 Cartridge installed in the forks. Springs can be mismatched to achieve the optimum net weight for example, one leg with 80 weight and the other with 90 weight would give a net weight of 85N/mm
