Progressive Federn BD11 1.90-2.20 20mm
This new spring matches the BD11 with a lower lever ratio than before. The overall setting is softer, making it a perfect match for the BD11's long suspension arms. You can find a good balance by choosing from this lineup for both front and rear.
The progressive type spring has a pitch change in the middle of winding, and its initial suppleness brings out a softer feel, making it easier to aim for the line, especially at the entrance of corners, etc. Compared to the BD11 standard spring, the push under is also reduced, allowing cornering with a high sense of grip even on asphalt surfaces. This allows for
high grip cornering even on asphalt surfaces.
