Ricor Race Suspension Intiminator’s


Spears Racing started working with the Ricor compony in the late 2000’s to build the best suspension product for the little bike racing world. The first patented inertia-activated front fork shock absorber designed to fit motorcycle


The Ricor Race Intiminator’s is a product that is only sold by Spears Racing and having the exclusivity to the “Race Valving/Set up” Intiminators. Spears Racing started working with the Ricor compony in the late 2000’s to build the best suspension product for the little bike racing world. Spears Racing has several of the top racers with amazing  ability to race in different parts of the USA and around the world to get this the best drop in suspension that will give the racer total confidence for the damper rod suspension motorcycles.

Facts of the product: The Intiminator once installed into the fork tube will seal its self to the inside of the fork with the Custom wear band(provided) unlike other brands that just sit on the damper rod and allows oil blow by/go around it. The Intiminator forms a seal to the inner of the fork leg and allows all of the oil to go thru the “Real Valve Stack” washers’

Can Suspension Systems Be Improved? Yes, if both the chassis and the wheel response are taken in to account during the design phase. Front Forks perform two important functions and, unfortunately, they are in direct conflict with each other. We rely on the suspension to stabilize our motorcycles during changes in direction and while accelerating
or braking (chassis motion). We also depend on forks to provide us with a comfortable ride and to allow the suspension to respond to changes in terrain so the tires can maintain traction (wheel motion). The following will discuss the challenges with today’s suspension systems and how this issue is solved using
RICOR’s Inertia Active Suspension technology Intiminators .

Technical Overview Ricor Race Intiminator’s
The problem with traditional shock absorbers is that they cannot distinguish between chassis motion or wheel motion They can be universally accepted that ‘stiff’ shocks equate to motorcycles stability and handling performance while ‘soft’ suspension provide better ride quality and superior traction over irregular road
surfaces. As polar opposites (stiff vs. soft), the benefits of one come at the direct expense of the desirable characteristics of the other. This is a universal problem and all traditional velocity-sensitive shock absorbers fall somewhere within the spectrum between these two extremes.

The solution employs a motion-sensing valve to determine whether movement is coming from the chassis or the wheel, as opposed to merely reacting to the relative movements between the two, like traditional shock absorbers. The second part is to use the position of the motion-sensing valve to open and close different fluid circuits that could each be tuned independently to provide exactly the right amount of resistance to chassis motion AND wheel motion.

In a sense, the design must put two different shocks with completely different characteristics into one package. The primary circuit is tuned to control chassis motion and the secondary circuit is tuned to control wheel motion.

The only suspension system on the market capable of delivering these results is RICOR’s Inertia Active Suspension Intiminator. It is able to recognize the difference between these two types of input and select the appropriate response instantaneously and automatically. As a result, RICOR’s Inertia Active Suspension is able to provide the optimum response to chassis motion and wheel motion without any of the compromises typically associated with traditional shock absorbers.

RICOR’s design ensures that the Inertia Active technology is ‘smart enough’ and that it cannot be ‘tricked’ into selecting the wrong circuit at the wrong time before the system can be considered viable. RICOR’s Inertia Active Suspension also is able to transition seamlessly between the chassis and wheel circuits because any benefits that variable-rate damping may provide would be totally negated if the transitions between those damping rates upset the handling characteristics of the vehicle.

These prove to be very difficult problems to solve, but hydraulically manipulating RICOR’s Inertia Active technology is the key to making shock absorbers work reliably, instantaneously and automatically. RICOR’s Inertia Active Suspension is hydraulically biased to select the chassis circuit over the wheel circuit if it detects wheel and chassis motion occurring simultaneously.

This makes Ricor Race Intiminator’s Suspension system virtually infallible – even in the unlikely event of any type of malfunction within the inertia active piston assembly – while also dramatically improving performance. The Intiminator design and performance can be greatly improved by using RICOR’s hydraulically manipulating Inertia Active Suspension technology and allowing the front forks to recognize whether the wheel or the chassis is in motion.

The results of this type of suspension design allow the vehicle:
• Increased stability in turns
• Increased cornering ability
• Reduced brake dive
• Smoother riding over the bumps
• Faster braking
• Less wallowing in turns
• Reduced softness at slow speed
• Less harshness over bumps
• Reduced bottoming out
• Better bike control
