For cost-efficiency reasons, new motorcycles are equipped with linear springs. Compressing the top half of this type of spring takes just as much force as compressing the bottom half. The result is that the top of the spring is in fact too rigid and the bottom too supple.
Fortunately, this perfect world does exist. Hyperpro
produces progressive springs whereby the top half is easily
compressible and compression of the bottom half is much harder. This
results in a perfect set-up for every situation. A number of benefits are mentioned below:
Improved braking distance
Whenever you apply the brakes, the pressure on the front wheel
increases. Regular springs cause the bike to 'dive' causing the brakes
to become less effective. With progressive Hyperpro springs the bike
takes less of a dive, the rate of resistance increases which results in
an improved braking distance. Not only is this faster on the racetrack,
it is also safer on the public highway!
Improved motoring performance
Small bumps and irregularities in the road surface get absorbed
immediately, large bumps or holes are intercepted by the 'more rigid'
part of the spring. This results in perfect harmony between control and
comfort.
No resonance
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!
Always a perfect setup
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.
We believe in our product and therefore offer a lifetime warranty against breakage. Tests have proved that even after driving a million kilometres our progressive springs maintain the same characteristics.
