What is Rising Rate Suspension?
In a normal spring, the coils are evenly spaced and compress at the same rate. For example, if you have a spring
that has ten coils spaced a centimeter apart, and you push down one centimeter on the spring, the entire spring
compresses one centimeter and each coil will then be 0.9 centimeter apart.
In a two-step linear spring (or one-step rising rate), about half the coils have shorter spacing. As the spring
compresses, the coils move closer. At a certain point, the shorter spaced coils touch, effectively eliminating
them from the spring. You then have a spring comprised of only the longer coils. This "second-step" spring will
be much stiffer than the whole spring (the more coils, the easier it is to compress the spring). The result is that
you have one set of handling characteristics before the shorter coils touch and then you have another,
completely different, level of response after they touch.
Unfortunately, your suspension needs do not come in only two flavors when you ride. They constantly change. In
a perfect world, it would take almost no force to start the coil compressing, but then as the down forces grow,
you would want the spring to become stiffer and stiffer in response, giving you maximum control, comfort and
braking.
Welcome to a perfect world
Giving you the "perfect world" is what HYPERPRO is all about. Each coil is spaced differently so as the spring
compresses and releases, it's characteristics constantly change. When the spring is at rest all it's coils are
available and it takes very little force for the spring to compress. As more force is added, more coils start to
touch making the spring stiffer. The more the force, the stiffer the spring. The result is a perfect setup in any
situation.
Why is this so important?
The benefits of a rising rate suspension are almost too numerous to mention. Since the effectiveness of your
suspension affects braking, handling, comfort safety and even lap times. HYPERPRO's rising rate springs give
you a fantastic range of benefits. That is why HYPERPRO has become famous all over the world.
Improved Braking
With HYPERPRO's constant rising rate springs, you have maximum efficiency when you brake. Here's why: as you
apply the brakes, the suspension loads the front tire. This results in the tire biting into the track causing more
load. In a normal spring this can result in a "dive". But with HYPERPRO's rising rate spring, instead of too much
dive you get increased resistance, giving the tire even more bite. This in turn puts more load on the tire further
stiffening the spring and creating a chain reaction of braking and traction. The result is improved braking.
Better Handling
Whether in town, on the highway or at the track, a rising rate spring improves handling performance. Since the
spring has a rising rate of resistance, it's very sensitive to small inputs such as imperfections in a road. This
means an incredibly smooth ride. However the spring also gives you the stiffness you need during hard braking
and turning. The end result is a perfect harmony of comfort and control.
Better Stability
HYPERPRO springs don't chatter. It's that simple. A stock spring has a specific frequency. If the spring
encounters this frequency while on the road it will start to resonate. You feel this as a dangerous and
uncomfortable chatter. Since HYPERPRO springs are rising rate, there is no single frequency that the spring will
respond to and they can't chatter. Your bike will show noticeably improved stability.
Better Road Holding
A rising rate spring means a smooth transition in response to a change in road conditions. Hit a bump and the
tire rises quickly at the beginning of the bump then stabilizes and lowers quickly on the back end, all in a fluid
motion. This means maximum rubber on the road at all times. In the rain this could be the difference between
maintaining traction and sliding. At the track and on the highway this means vastly improved tire wear.
If you race, think about what it means to get ten more laps out of a set of tires. If you ride on the street, think
about the money save by buying one less set of tires.
Always a Perfect Setup
The more force you put on a HYPERPRO spring, the greater the resistance. This means a HYPERPRO spring will
automatically adjust if you put a passenger on your bike. It will also automatically adjust to your weight. If you
weigh 50 kg or 150 kg, a HYPERPRO spring gives you a perfect setup right out of the box. HYPERPRO springs
even respond to changes in the amount of fuel in your tank!
HYPERPRO springs are an engineering work of art. Backing up this claim is a lifetime warranty against breakage.
Each spring is constructed of the finest grade of chrome-silicon wire and is guaranteed not to sag even after
1.000.000 miles of use. Each spring is shot-peened for strength and durability and then polished to reduce
friction and eliminate fork oil contamination.
The Only Complete Package
Why suffer? Every HYPERPRO Combi kit comes with a complete package that includes springs, fork oil, decals,
and a thorough manual that not only walks you through every step of the installation, but also tells you how to
set your bike up for a perfect ride.
Try a set of HYPERPRO springs and feel the difference yourself!
