This is Yokomo BD11 1.80-2.10 20mm Progressive Spring 2 pcs. It is a new spring that matches BD11 with a lower lever ratio than before. Overall, it has a soft setting, and it goes well with the long suspension arm of BD11. By choosing from this lineup for the front and back, you can find a good balance.
It is a progressive type that changes the pitch during winding, and the initial suppleness brings out a soft feel of operation, making it easy to aim the line, especially at the entrance of corners. Compared to the BD11 standard spring, push-under is reduced, so cornering with a high grip feeling is possible even on asphalt roads.
