Personalized Handling for Your Style of Riding
At Precision Concepts, we believe suspension is the one of the most influential components on your motorcycle that you can improve upon, and that the handling character of your bike can have a dramatic impact on your riding experience. Having a suspension set-up that is customized for your needs increases the predictability and comfort of your machine. This can help you ride faster, ride safer and ride longer, which ultimately leads to more enjoyment.
Whether you bought a dirt bike new or used, chances are high that the suspension isn't set up for your unique riding style and preferred terrain. For this reason, we specialize in personalizing the handling of your motorcycle. As a result, we want to help you feel more confident and comfortable every time you ride.
The Revalve Process
The first step of your revalve is for us to get to know you as a rider. We want to learn your preferred riding terrain, your style, and what characteristics of your bike you currently like and dislike in order to personalize your suspension. In order to do this, we'll have you fill out our Rider Profile form to collect the general info.

If you're dropping the suspension off to us in person, we'll collect any further information we may need at that time. In addition, we do also offer a suspension removal and remounting service, should you prefer to bring your complete bike. Should you be shipping your suspension, we'll contact you over the phone for any additional info needed.
If you do prefer shipping your suspension to us, then click the button to visit our Shipping Info page.
Your Customized Valving
Once we receive your suspension, it'll first be completely disassembled, cleaned and inspected for any parts that need replacing. Then, we'll go to work installing the custom valving spec that was created specifically for you. Your valving spec is the result of over twenty years of experience working with all different levels of riders. We've worked with the fastest racers in the grand prix, desert and motocross disciplines as well as weekend warriors, play riders and adventure enthusiasts. As a result, we've learned what can work for any skill level and type of terrain.
We give your suspension the same level of work and attention to detail as the factory-level racers that we support. Furthermore, we go beyond simply replacing shims; we chamfer and polish any edges of the internal moving parts for smoother oil flow and less friction. In effect, this gives better performance and a more predictable end result to our revalve. We'll, then, reassemble your suspension using high-quality oils and replace any parts that need it. This would include bushings, seals, and springs (should they be required).
Our Work is 100% Guaranteed
Our commitment doesn't finish when you pick up your suspension. We guarantee your 100% satisfaction with the result of your revalve. We also realize that you don't always know exactly what you like until you ride it—especially when it comes to handling characteristics. Because of this, we'll continually be available to offer technical support for clicker positioning and adjustments. We also offer an online resource page to give you an introduction and basic guidance for clickers and setting sag. Click the button to view our resources page.
Furthermore, if after attempting external adjustments, you're still not totally satisfied with the handling of your bike, we'll revalve it again, free of charge, based on your continued feedback. Your satisfaction is our number one priority. To emphasize, we want to make sure we achieve our goal of giving you more comfort and confidence in the handling of your bike.
You Only Pay for a Revalve Once
Our guarantee also doesn't finish there. It lasts for as long as you own your bike. Specifically, this means that if in the future you were to have any factor necessitate internal modification to the same set of suspension we've already revalved—e.g. gain or lose weight, increase your speed or skill—we'll update the valving for the price of a suspension service. In summary, you only ever pay for one revalve on any one set of suspension.

Why Revalve Your Suspension?
Suspension performance is one of the most subjective features of a motorcycle. There is no “perfect” set up because what works for one person likely won’t work for the next. Even two riders of identical weight and ability will have minor variances in riding technique. This will make the exact same suspension set up feel and work differently for either rider. The reason to revalve your suspension is to customize it so it works perfectly for you.
As an example, if you push the front end really hard into corners on the track, you’ll want a stiffer fork valving. Alternatively, if you don’t want to feel the washboard chop on your long adventure rides, you’ll want a plusher set up. Furthermore, if you weigh a hundred forty pounds and ride a 450, you’ll likely need your suspension valved a little softer. Some motocross riders like a plusher feel, while others actually prefer a bit of feedback, or “harshness”, because it helps them better feel the traction and terrain.
The point is, suspension set up is incredibly personal. With this in mind, getting your bike working for your unique size, weight, skill, style and preferred terrain can drastically impact your riding experience.
What is a Revalve?
Whether discussing a set of forks or a shock, held up by spring or air, all suspension creates damping in a similar fashion. Suspension relies on the hydrodynamics of pushing oil through a chamber. In the simplest terms, this means that as a shock shaft moves through the shock body—which is filled with oil—the resistance generated produces a damping effect.
The shock shaft will have a piston assembly affixed to its end. This piston is strategically porous to allow oil to flow through. Atop the piston there are numerous shims of varying thickness and diameter stacked upon each other. As oil flows through the piston, the shims bend in response, creating resistance. The thickness and diameter of the shims, along with their quantity and arrangement, all directly affect how much bending resistance they will have, and the damping feel of the suspension as a result. This “shim stack” is commonly referred to as the “valving” and is the main focus of our suspension revalve. By reworking the shim stack, we can “revalve” the suspension, changing its handling character and customizing it for each client.
More Than Simply Replacing Shims
There are numerous other factors that have some impact over how the suspension will work. Just a few examples will be the diameter of the fork/shock body, which can change the flex character of the suspension; the internal tolerances of the moving parts, as unwanted friction typically offers a harsher feel and makes the performance of the revalve less predictable for the suspension tuner; the piston design, which will impact how much and how rapidly oil flows onto the shim stack; and many, many more variables.
At Precision Concepts, we put in the effort to control as many of these factors as possible. Therefore, we will hone, polish and replace parts as necessary to improve the final result. To emphasize, that result is customizing your suspension to work specifically for you so you can better enjoy your passion. Ultimately, we want to help you ride safer and faster, with the most comfort and confidence possible.
Are There Any Limitations?
There are some limiting factors that can impact the result of a revalve. The most obvious would be the quality of the suspension and its internal parts. This would pertain to the tolerances and materials used by the suspension manufacturer. It can also refer to the style of fork; for example, some regard the 4 Chamber System (4CS) fork as having limited performance. Suspension is also massively affected by the chassis on which its mounted. If you were to take the suspension off of a Honda CRF450R and mount it onto a Suzuki RM-Z450, the handling wouldn’t even feel like it was in the same universe. These elements may be somewhat out of your control, but there are other factors that are within your control that can influence the handling of your bike.
Aftermarket Accessories Can Impact Your Bike's Handling
The rigidity of your triple clamps would be one example of an aftermarket accessory that can change the feel of your bike’s handling. Rigid triple clamps can take a plush, compliant front end and make it feel supercross stiff. Alternatively, an overly flexy set of triple clamps can make the front end feel vague and hurt cornering traction. Another one of our favorite examples is your choice of skid plate. A plastic skid plate will have a negligible effect on your bike’s handling. Do nothing other than change to a hard-mounted aluminum skid plate and the character of your bike can change dramatically. It can make the rear end feel harsher and more likely to deflect over sharp bumps.
We Can Help You Decide What's Best
With these thoughts in mind, it’s important to understand the effect of any aftermarket accessories you may be considering. To be clear, this isn’t to dissuade you from changing a part or accessory for performance or style. We simply want to empower you with the knowledge that it may have an effect on your bike’s handling. Our staff at Precision Concepts has decades of experience with the effects of different parts and accessories on handling character. As a result, we help you make the right decisions for the performance (and style) of your bike.
Who Can Benefit from a Revalve?
The quick answer is that everyone can benefit from revalving their suspension. Most motorcycles come from the manufacturer with a generic suspension set up that will work reasonably adequate for a wide variety of riders. By and large, it isn’t set up with your unique needs in mind. Personalizing your bike’s handling can be of huge benefit. It can make you feel safer and more confident. Notably, it can allow you to charge into the next corner faster, or take some of the fear out of casing that jump. And it can also make the difference during an all-day ride in the desert, thereby improving your level of comfort and endurance. To summarize, whether you’re racing your buddies through the trails; aspiring to be a professional motocross racer; or a weekend warrior who just likes to ride in the hills with your friends, your suspension can definitely be customized to improve its performance for you.
