Yes, the Ohlins & Maxton cartridges make both legs adjustable.
Both for pre-load, left for rebound damping & right for compression damping. That’s the best option for any bike imho. It’s simple, the damping in each leg is very efficient (less cavities in each leg as they’re doing 1 job each) but is the most expensive.
There is a maxton option, same as k-tech, which puts new spring in right leg, plus both damping valves in the left leg with new fork tops with a full new cartridge in left leg. It’s basically a cartridge and valves upgrades to the left leg, making improvements but not ideal.
