Circuit tests A circuit and a Kawasaki Z1000, that was all that was necessary to introduce the world to Hyperpro products. Regrettably, the converted Z1000 has disappeared now, but the circuit is still very much in use to thoroughly test new products in combination with new motorbike models. These circuit tests enhance our products. Not only is riding on the public highway more comfortable and safer thanks to our steering dampers and springs, on the circuit they guarantee improved motoring performance and faster lap times. A Hyperpro steering damper ensures better control of the motorbike and prevents tank slappers. Our progressive springs warrant a more balanced bike, taking less of a dive during braking. This results in a more efficient braking action and a shorter braking distance.
