Description
It is a new spring that matches BD11 with a lower lever ratio than before. Overall, it has a softer setting, and the compatibility with BD11's long suspension arm is outstanding. By choosing from this lineup for the front and back, you can find a good balance.
A progressive type in which the pitch changes 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.
