Twinshock Bobber Conversion SE Performance Shock Absorbers 450mm +-7mm

Twinshock Bobber Conversion SE Performance Shock Absorbers 450mm ±7mm

The SE Performance shock absorbers for BMW Twinshock models were developed specifically for demanding bobber conversions. With a length of 450 mm, they allow for a completely new chassis positioning and are intended for conversion concepts where the shock absorbers are mounted directly to the front of the main frame.

For this type of BMW bobber conversion, we recommend reinforcing the upper shock mount on the main frame accordingly. At Sport-Evolution, we also perform such conversions in their entirety in our workshop, including TÜV approval.

These high-quality gas-pressure shock absorbers feature machined 38 mm damper housings and are extensively adjustable from the outside. The external gas reservoir is separated from the oil filling by a separating piston. This reduces foaming and supports consistent damping even during rapid compression movements.

Spring preload, rebound, and low- and high-speed compression can be adjusted individually. In addition, the shock absorber length can be adjusted by ±7 mm at the shock eye. No special tools are required for basic adjustment work.
