Deciding to revalve suspension is usually the moment a rider stops fighting their machine and starts actually enjoying the ride. Most of us spend way too much time fiddling with clickers, hoping that two turns of compression will magically fix a bike that feels like a jackhammer on small bumps. But the truth is, those external adjusters can only do so much. If the internal shim stacks aren't designed for your weight, your speed, or the specific terrain you're tackling, you're basically just putting a band-aid on a broken leg.
When you buy a bike off the showroom floor, the manufacturer has a "target rider" in mind. Usually, that's someone who weighs about 175 pounds and rides at a moderate, intermediate pace. If you happen to be a 220-pound woods rider or a 140-pound motocross prodigy, that stock setup is going to feel either like a pogo stick or a rigid piece of steel. That's where the magic of a revalve comes in. It's about tailoring the internal flow of oil to match exactly how you ride.
What actually happens inside the forks and shock?
To understand why you'd want to revalve suspension, you have to look at what's happening inside those tubes. It's not just springs and oil; it's a complex system of shim stacks. These shims are thin, circular pieces of metal that sit against a piston. As your suspension compresses or rebounds, oil is forced through ports in that piston, and the shims have to bend out of the way to let it pass.
The thickness, diameter, and number of those shims dictate how much resistance the oil meets. When a tuner performs a revalve, they're basically rebuilding those stacks. If you're hitting square-edge rocks and the bike feels harsh, they might pull some shims out to let the oil flow faster on high-speed impacts. If the bike feels "wallowy" or dives too much when you hit the brakes, they'll add shims to create more low-speed damping. It's a delicate balancing act that changes the entire personality of the bike.
Why clickers aren't enough
We've all been there—standing on the side of the trail with a screwdriver, clicking away. "Three clicks out on compression should fix it," we tell ourselves. While those clickers are great for fine-tuning based on the temperature or a slightly different track surface, they have a very narrow range of influence. They mostly control the "bleed" of the oil through a small bypass hole.
The problem is that once the suspension moves past a certain speed or depth in the stroke, the shim stack takes over completely. If that stack is too stiff, no amount of "clicking out" is going to make the bike feel plush. You'll just end up with a bike that's simultaneously soft at the top of the stroke and harsh in the middle. It's a frustrating cycle that usually ends with a rider feeling fatigued and frustrated. When you revalve suspension, you're shifting the baseline so the clickers actually live in a range where they're useful again.
It's about more than just comfort
A lot of people think a suspension revalve is just for people who want a "couch-like" ride. While comfort is a huge part of it, the real benefit is traction and safety. A bike that's properly valved keeps the tires in contact with the ground more consistently. If your suspension is too stiff, the tire will deflect off every little pebble and root, which means you're losing grip.
Think about coming into a corner with a lot of braking bumps. If your forks are valved correctly, they'll soak up those bumps while keeping the front tire pressed into the dirt. If they're stock and poorly matched to your weight, they might "pack" down or bounce off the tops of the bumps, making it feel like you're riding on marbles. A good revalve gives you the confidence to stay on the gas because you know exactly how the bike is going to react.
Finding the right person for the job
This is probably the most important part of the process. You can't just drop your suspension off at any shop and expect a miracle. You need a tuner who actually asks you questions. If they don't ask how much you weigh, what kind of terrain you ride, and what your specific complaints are, turn around and walk away.
A good tuner acts a bit like a doctor. They'll want to know if the bike feels "busy" in the rear, if it stinksbugs under braking, or if it feels dead on landings. The more feedback you can give, the better they can tailor the shim stacks. It's also worth looking for someone who specializes in your specific type of riding. A guy who builds national-level Supercross suspension might not be the best choice for your 50-mile technical enduro loops.
The feedback loop
Once you get your suspension back after you revalve suspension, the work isn't quite done. You'll need to go out and test it. Most tuners expect you to call them back after a ride or two. "Hey, it's 90% there, but it's still a little harsh on the initial part of the stroke," is exactly the kind of info they need. Sometimes it takes one minor tweak to get it perfect, but even the first version of a custom revalve is usually leaps and bounds better than stock.
Is it worth the investment?
Let's be real: revalving isn't cheap. Between the labor, the oil, the seals, and maybe some new springs, you're looking at a decent chunk of change. However, if you compare it to other mods, it's almost always the best "bang for your buck." Riders will spend $1,000 on a titanium exhaust system that adds two horsepower they can't even use, but they'll hesitate to spend half that on suspension that would make them five seconds a lap faster.
When your bike handles well, you don't get tired as fast. When you aren't fighting the handlebars to stay on track, you can focus on your technique and your line choices. For most of us, that's worth every penny. It turns a bike that feels like a chore into a bike that feels like an extension of your own body.
Common myths about revalving
There's a lot of misinformation out there about what a revalve can and can't do. One of the biggest myths is that you only need it if you're a pro. In reality, beginners often benefit more from a revalve. Pros have the strength and speed to manhandle a poorly set-up bike, but a beginner will get beat up and discouraged by a bike that's too stiff or unpredictable.
Another myth is that you can just "copy" a friend's settings. Unless your friend is exactly your weight, height, and speed, their "perfect" setup will likely feel terrible to you. Suspension is deeply personal. What feels "plush" to one person might feel "mushy" to another. That's why the custom nature of the work is so vital.
The end result
At the end of the day, the goal of choosing to revalve suspension is to make the bike disappear beneath you. You want to reach a point where you aren't thinking about the forks or the shock at all. You're just looking ahead, picking your lines, and enjoying the ride. If you find yourself constantly thinking about how much your hands hurt or how the rear end is kicking side-to-side, it's probably time to stop clicking and start valving. It's an investment in your riding experience that pays off every single time you unload the bike from the truck.
