A linear spring has a specific frequency and therefore, could resonate at that particular frequency. Resonance is not only very annoying it can also be dangerous. Progressive springs do not have a frequency so therefore never resonate; an obvious difference! Progressive springs always adjust themselves instantly to changing circumstances. If you carry a passenger on your motorcycle, the spring should provide more resistance and this is certainly the case with progressive springs. Hyperpro progressive springs even respond to the amount of fuel left in your tank.
