What RaceTech suspension is and why riders choose it

RaceTech is a suspension tuning and component company that modifies how your motorcycle's forks and shock absorber behave. Instead of replacing your entire suspension system, RaceTech typically works with what you already have — they rebuild your existing forks and shocks, change the internal oil, adjust spring rates, and install different valving to match your weight, riding style, and the roads or tracks you use.

Riders choose RaceTech because stock suspension — the forks and shocks that come on most motorcycles — is built to work acceptably for a wide range of riders and conditions. That means it rarely works optimally for any single rider. A RaceTech rebuild makes your suspension respond the way your particular bike and body need it to, which changes how the motorcycle handles bumps, corners, and acceleration.

The work is done by RaceTech technicians at their shop in Corona, California, or by authorized dealers in your region. You ship your forks and shock to them, they rebuild and tune them, and you install them back on your bike. The process typically takes two to four weeks depending on their current workload.

Key Takeaways

  • RaceTech rebuilds your existing forks and shock absorber rather than replacing them, adjusting internal valving and oil to match your weight and riding style.
  • The main tuning variables are spring rate (how stiff the suspension is), compression damping (how fast it compresses), and rebound damping (how fast it extends back).
  • You will need to know your body weight, the type of riding you do most, and your current suspension complaints before sending components in for a rebuild.
  • Costs vary by component and service level, ranging from basic revalving to full rebuilds with new internals, and you handle shipping both directions.
  • A RaceTech suspension will not fix frame geometry or tire grip, so results depend on whether suspension tuning is actually what your handling problem needs.

How suspension tuning actually changes what you feel

When you hit a bump, your fork compresses downward. Inside the fork tubes, oil flows through small passages called shims — thin metal discs that control how fast that oil can move. The speed at which oil flows determines how quickly the fork stops compressing. This is called compression damping. If compression damping is too high, the fork feels harsh and doesn't absorb the bump smoothly. If it's too low, the fork dives too far and feels mushy.

After the bump passes, the fork needs to extend back to its original height. That extension is controlled by rebound damping — another set of shims that slow the oil flow on the way back up. If rebound is too fast, the fork bounces and feels unstable. If it's too slow, the fork stays compressed and the bike sits lower than it should, changing your steering geometry.

The spring rate — how stiff the spring itself is — determines how much the suspension compresses under your weight before you even hit a bump. A spring that's too soft for your weight means the suspension is already partially compressed when you're just sitting on the bike, leaving little room to absorb bumps. A spring that's too stiff feels like riding on a pogo stick.

RaceTech adjusts all three of these variables. They change the shim stack (the arrangement and thickness of those metal discs) to alter damping, swap in springs matched to your weight, and adjust the oil viscosity and volume to fine-tune the overall feel. The result is suspension that compresses and extends at the right speed for your specific situation.

What information you need before sending components in

RaceTech will ask for your body weight (in gear, if you ride with a full suit), your motorcycle model and year, and what you use the bike for — street riding, track days, racing, commuting, or a mix. They also want to know what your current suspension feels like: does it feel harsh over bumps, does it dive under braking, does it bounce after hitting a bump, does the rear wheel lose traction on acceleration, or does it feel vague in corners?

If you have ridden other bikes or had suspension work done before, tell them what you liked or disliked about those setups. If you know your current spring rates or have any documentation from previous work, include that too. The more specific you are about what bothers you, the better they can tune for your needs.

You will also need to decide what level of service you want. A basic revalve keeps your existing springs and internals but changes the shim stack and damping. A full rebuild includes new seals, new oil, and often new springs and internal components. A rebuild costs more but gives you a suspension that's been fully inspected and restored, not just retuned.

The shipping process and what to expect during the rebuild

You remove your forks and shock from your motorcycle yourself — this is standard maintenance that most riders can do with basic tools, though some prefer to have a shop do it. You then pack them carefully and ship them to RaceTech or an authorized dealer. RaceTech provides shipping instructions on their website to make sure components arrive safely.

Once they receive your parts, RaceTech inspects them, confirms the work you've requested, and begins the rebuild. You can usually check the status online or by calling. The actual rebuild work takes a few days to a week, but the total time from drop-off to shipment back to you is typically two to four weeks because of inspection, testing, and shipping queues.

When your rebuilt suspension arrives back, you or a shop installs it on your bike. RaceTech includes setup instructions, and many riders find that the difference is noticeable on the first ride — the bike may feel more planted in corners, absorb bumps more smoothly, or feel more stable under braking, depending on what was changed.

Cost and what's included in different service levels

RaceTech pricing varies by component and service. A basic revalve of a fork typically costs less than a full rebuild, which includes new seals, springs, and internal parts. A shock rebuild costs differently than a fork rebuild because shocks are more complex. You pay for the work itself, plus you cover the cost of shipping your parts to them and back to you.

Some authorized dealers offer local service, which may save you shipping costs and time. Check RaceTech's website for dealers in your region. Pricing also depends on whether you need new springs (which depends on your weight and what the original springs were) and whether you want any special features like adjustable compression or rebound knobs on the outside of the forks or shock.

Budget for the work itself, shipping both directions, and any new springs or seals if they're needed. The total investment is typically several hundred dollars, which is less than buying a complete aftermarket suspension system but more than basic maintenance.

When RaceTech suspension helps and when it doesn't

RaceTech suspension works best when your handling problem is actually a suspension problem. If your bike feels harsh over bumps or unstable after hitting a pothole, suspension tuning will likely help. If the front end feels vague in fast corners or the rear wheel spins up too easily on acceleration, damping and spring rate changes can make a real difference.

RaceTech suspension will not fix problems caused by frame geometry, tire grip, or brake power. If your bike understeers (pushes wide in corners) because of the frame design or because your tires are worn, a better suspension won't solve that. If you're sliding out because your tires don't have enough grip, suspension tuning won't add grip. If your brakes aren't strong enough, suspension won't help you stop better.

Before you send your suspension in, ride the bike on a variety of roads and try to identify whether the problem is really suspension-related. Does the bike feel better or worse after you warm up the tires? Does it handle differently on smooth pavement versus rough pavement? Does the problem happen in specific situations like hard braking or hard acceleration? These clues help you and RaceTech figure out whether tuning is the right answer.

Frequently Asked Questions

Can I ride my bike while my suspension is being rebuilt?

No — your forks and shock are removed from the bike and sent to RaceTech, so the bike cannot be ridden. Plan for two to four weeks without the bike, or arrange to have the work done during a season when you ride less. Some riders have a second bike or borrow one while their suspension is being worked on.

Do I need to replace my suspension if I want RaceTech tuning?

No. RaceTech rebuilds and retunes your existing forks and shock. You keep the same components; they're just internally modified. This is less expensive than buying a complete new suspension system, though a full rebuild does include new seals and internal parts.

What if I don't know what my suspension problem is?

Call RaceTech or an authorized dealer and describe how the bike feels — harsh, bouncy, vague, unstable, or something else. They can usually tell from your description whether suspension tuning will help or whether the problem is something else. Many dealers offer a free phone consultation to figure this out before you commit to shipping parts.

Will RaceTech suspension work on any motorcycle?

RaceTech works on most motorcycles with conventional forks and a rear shock, which includes most street bikes, dirt bikes, and sport bikes. Some bikes with unusual suspension designs may not be compatible. Check RaceTech's website or call to confirm your specific motorcycle model can be serviced.

How long does a RaceTech rebuild last before I need to do it again?

A full rebuild with new seals and internals typically lasts several years of regular riding before seals wear out and damping performance degrades. A basic revalve lasts as long as the original internals hold up. Maintenance like checking fork oil level and keeping seals clean extends the life of any rebuild.
