Pro Series Showa 49 Fork Kit

Pro Series 49mm Showa Fork Kit

Built for Fast B-Level and A-Level Riders Who Need Maximum Hold-Up, Control & Speed Stability

The Pro Series 49mm Showa Fork Kit is engineered for riders who push harder, hit obstacles faster, and demand more support than what the Control Series is designed to deliver.
Where the Control Series focuses on plushness, comfort, and consistency for juniors, vets, and general off-road riders, the Pro Series is built for aggressive speed, big hits, and high-level motocross performance.

This kit combines our two most advanced components—the Showa 49 Fork Piston Kit and the Showa 49mm Midvalve Post Assembly—to completely rebalance fork performance for elite-level control, traction, and hold-up.

What’s Included

Showa 49 Fork Piston Kit

• Piston design for improved oil movement at race pace
• More precise damping response in choppy or high-impact terrain
• Pre-assembled to spec with matched posts for true bolt-on consistency
• Multiple shim settings + optional shims included Soft to Firm.
• Complete data/spec sheets for rebound and midvalve compression (two recommended settings)

Showa 49mm Midvalve Post Assembly

• (2) Precision-machined midvalve posts
• (2) Custom flat washers
• (2) Secure locking nuts
• Compression & rebound shim stacks designed to use along with OEM piston
• Two complete midvalve compression settings included (fast B + A level)
• Optional shims supplied for easy adjustment
• Rebound setting is matched to the fork spring rate installed

Why Choose the Pro Series Kit?

1. Superior Hold-Up for Fast Riders

The Pro Series allows you to run a slightly softer main stack for improved small-bump compliance without sacrificing support at high speed.  This is achieved by balancing the forks compression alongside a trampoline or 'leaf' style midvalve.  Changing this balance allows for superior holdup and also tunable plushness.
Perfect for riders who charge into braking bumps, land hard, or carry more corner speed.

2. Race-Level Damping Control

The piston kit improves oil flow to reduce harsh spikes and create a more predictable, controlled front-end feel—especially under load or at pace.

3. Balanced, Confidence-Inspiring Ride

Our midvalve-centric damping design shifts more of the workload away from the OEM top-compression valve.

The result:

• More controlled midstroke
• Better holdup in rough terrain
• Less harshness
• A more positive, “in-hand” rider feel compared to stiff OEM setups

4. Mimics Elite Factory-Level Behavior

This internal damping balance is similar to what other top-level Pro suspension manufacturers and systems use, giving the Showa 49mm fork a drastically improved ride character without needing exotic parts.

How It Works

OEM Showa forks rely too heavily on the upper compression valve, which creates harsh, inconsistent feedback.
Our Pro Series Kit integrates a leaf-style midvalve system, shifting damping control to where it’s more effective. This allows you to:

• Use a softer main stack
• Improve comfort in chop
• Gain significantly better hold-up
• Reduce bottoming
• Increase speed stability

The enhanced oil flow from the 32mm face piston completes the system, ensuring consistent damping and easy tuning softer and firmer , even in long motos or rough conditions.

Who It’s For

Recommended:

✔ Fast B-level, A-level, and expert riders
✔ Racers who hit obstacles faster and need reliable support
✔ Riders who find stock forks harsh, deflective, or unpredictable at speed

Not Recommended:

✘ Junior riders
✘ Vet riders seeking plushness
✘ Slower off-road or recreational riders
(These riders benefit more from the Control Series, which focuses on comfort and compliance.)

Take Your Suspension to a Pro Level

The Pro Series 49mm Showa Fork Kit delivers a complete performance transformation—greater control, stronger hold-up, and a balanced, race-ready feel that rewards speed and precision.

If you want the fastest, most capable version of the 49mm Showa fork, this is the system designed for you.
