Athena Variomatik Gegendruckfeder
- blue feather: 22 KG
A harder counter-pressure spring results in a later switching of the converter, which has a better effect on the motor. When using a sports exhaust, it may be useful to use a harder back-pressure spring to obtain better acceleration.
Filling lighter weight weights and a harder counter-pressure spring can have a disadvantageous effect. Please try one at a time!
The different spring thicknesses differ by the color.
Athena specifies the differences in kilograms that press against the transducer:
