Front Fork and Shock Springs The Foundations of Excellent Suspension
Reactive Suspension offer a wide range of high quality fork and shock springs for road and motocross bikes. Selecting springs from Hyperco, Ohlins, WP and Racetech we are able to match springs to your requirements.
The starting point in upgrading any suspension system is ensuring that the spring rates are matched to your weight, riding style and the terrain you are riding on.
Customised spring rates ensure the bike has the correct balance front to rear and the correct amount of travel, bikes which do not support the mass of bike and rider sufficiently will have reduced travel and bottom out easily, bikes with too stiff a spring rate will feel harsh over bumps.
Hyperco Shock Springs
Hyperco's focus is constantly on innovation, research and development and endlessly testing new ways to improve performance, not just coiling springs but engineering suspension coils that ultimately offer a Performance Advantage.
While other companies offer springs as a part of their expanding product line, Hyperco’s focus is on high performance suspension coils. Customers can be assured they are not distracted by other products; trying to be all things to all people, their team of specialists continually work to manufacture a spring that maximises performance for every application. Hyperco utilise the latest in design and performance simulation software, the most up to date manufacturing equipment along with multi axis rate and load testing equipment to measure overall dynamic performance ensuring that all springs offer consistent performance, exclusive technological advancements and reliability.
In a planned phased transition Hyperco are moving over to the Optimum Body Diameter Spring, this is the very latest breakthrough in spring technology featuring a design where the main body diameter is greater than that of the end coils resulting in a spring with improved rate linearity, more resistance to bowing, additional shock to spring clearance and a lighter weight.
OBD springs fit all standard hardware, over time, 100% of the line will be produced in the OBD configuration.

Load Centralizing Hydraulic Spring Perches
An inherent characteristic of coil springs is that as they compress they produce a lateral, or sideways load acting on the shock shaft trying to bend it resulting in highly increased frictional forces within the damper, these extra forces give lowered tyre grip levels, and increased tyre wear.
The assembly allows the end coils of the spring to tilt (up to 4 degrees) as compressive loads are applied centralising the loads fed into the shock. The result is that up to 96% of the bending is eliminated increasing mechanical grip.
The spring perch can be used with any existing shock absorbers fitting between the existing spring collar and the spring.
Titanium Springs 57mm Internal Diameter, 150mm Free Length
The properties of titanium allow a larger wire diameter and fewer coils to be used to achieve the same spring rate to that of an equivalent steel spring, the resulting Titanium spring is both significantly lighter (typically by 40%) and will provide more travel due to having fewer coils.
The reduced weight of a titanium springs lowers the unsprung mass of the suspension generating less inertia, contributing to a more responsive suspension action and maximum tyre contact.
Fork Springs
A High Performance Spring has a high stiffness to mass ratio, in other words it is as light as possible for a particular rate. Manufactured from chrome silicon steel, shot peened, heat-treated and pre-set for length, they are the finest springs available. We test all our springs before despatch or fitting to ensure they are the exact rate you require.
Fork Spring Buffer Kit
Being a long narrow spring, fork springs bow as the compress, when they bow they rub on the inside of the fork tube, this rubbing action causes wear on the spring and contaminates the oil, by using a smaller O.D spring and internal buffer this wear and contamination is prevented. The buffers are available for 10mm and 12.5mm damper rods.
