Race Tech Gold Valve

All Models

G3-LD Gold Valves provide better control for any rider by creating more shim leverage and decreasing the angular shim deflection.

Top suspension performance requires firm bottoming resistance with plushness at the same time. Even the best suspension tuners can only make the stock valving design work so well. The Gold Valve Shock Suspension System is a proven bolt-on shock valving system that improves control, traction, performance and bottoming resistance.

You can also add a K-Tech Bladder Conversion with this revalve for better small bump compliance and less heat / fade.

WP AER / Xact 48

2021 + Gas Gas – MC / EX

Race Tech Revalve

Replaces the Mid-Valve and Compression valve with Gold Valves.  Tuned for your weight and riding style.  Better hold up with less deflection and harshness in the mid stroke. 

K-Tech Suspension ORVS Fork Piston Kit

K-Tech ORVS re-valve system is a direct replacement for the WP AER48 systems standard valving. The ORVS kit includes complete compression and rebound assemblies with new pistons & finer adjustment needle along with K-Tech’s unique billet fork cap for improved range of adjustment,  giving better options for all terrains including sand, hard pack and rocks, increasing grip, cornering & maximizing overall ride quality and stability for a safer and more positive control of the motorcycle.
Designed and manufactured in the UK
Tighter tolerance for improved performance over original equipment parts
Improved adjustment range
Complete assemblies for ease of fitment
Increase comfort and confidence 

K-Tech Suspension Off Road Spring System Cartridges

Tired of the inconsistency and having to check the pressure of your Air Fork.  This will replace the air chamber with a spring.  Although heavier then the stock air chamber this eliminates the inconsistency you get with air and has the reliability of a traditional air fork.  The Dal Soggio conversion is a drop in system with external pre-load adjustment. 

Lainer Suspension Epica Cartridge

Our new EPICA Cartridge System is the culmination of years of experience, testing and development into a single project. The main goal for this project was to develop a highly tunable cartridge to allow riders to fine tune their forks in ways that was never before possible. Below is a break down of the key features of this innovative design.

External adjustments:

Compression damping60 clicks of sensitive adjustmentAdjustment at top of cartridge.
Rebound damping50 clicks of sensitive adjustmentLocated at fork bottom
External spring preload adjustment0 to 15mmEasily adjusted with a 16mm socket at the fork bottom.

Innovative Features:

  • Bladder System
  • Our bladder system prevents performance loss that can occur with standard internal spring systems (due to hydraulic support decay).
  • Internal oil compensation with increased volume for better high speed response.
  • Ability to tune bladder pressures via the side bleed spring.
  • EPICA cartridge incorporates Lainer’s Progressive Damping System (PDS) for increased hydraulic damping at the end stroke.
  • PDS system has up to 12 different adjustments for the end stroke stiffness.
  • High Speed compression piston is reversible with a large range of settings.

Technical Specs:

  • Machined from premium 7075 and 6060 alloys and hard anodized.
  • Reversible High Speed compression piston – outer diameter = 38 mm.
  • Side A (Flat valve surface) – 34mm OD shims for motocross and enduro.
  • Side B (Convex valve surface) – 32mm OD shims for supercross.
  • Option to configure Low Speed Valve (LSV) on compression base valve.
  • Cartridge rod diameter = 14 mm (for an increased oil flow).
  • Rebound piston diameter = 25mm for better hydraulic control.
  • Compression high/low speed shims ID 12 mm.
  • Maximum travel = 310 mm.
  • Maximum shim diameter for Mid-Valve By-pass = 21 mm.
  • Ability to set Mid-Valve float clearance with the stack shims.
  • Mid-Valve/By-pass floating shim ID = 6 mm (for a soft response at high speed on the braking bumps).
  • Rebound shims ID = 6 mm (uses triangular mid-valve shims to avoid any oil turbulence on compression).
  • Low friction NBR bottom seal.
  • Ability to extend the cartridge through the nylon washers.

Dal Soggio Sphere Cartridge System

SPHERE HYDRAULIC CARTRIDGE is an innovative hydraulic cartridge for Race performances by Dal Soggio, excellent for off-road discipline, especially for enduro but also well adaptable and high performing for motocross too. Look Sphere Gallery

Why choose SPHERE?

The answer is very simple. This particular sealed and pressurized cartridge considerably increases precision and sensibility of the forecarriage, giving better feeling on driving. As consequence this will entail beyond safety, also a big pleasure and fun when you’ll ride your motorbike, both you are doing an important race both you are enjoy yourself with friends.


Thanks’ to 38 clicks available, it provides a wider and more precise regulation of compression.


The automatic bleed valves are calibrated one by one in our laboratory, to ensure the correct internal pressure.


The pressurized bladder system guarantees a greater sensitivity to the fork.


The compression piston is made in ERGAL 7075 with an hard oxidation treatment. The oil’s crossings are 4 and no more 3 to ensure a greater and more precise oil flow.


The compression piston is made in ERGAL 7075 with an hard oxidation treatment.

The 4 oil’s crossings decrease the wear of oil and shims. The slide camp (made with teflon treatment) serves to give a greater sensitivity to the hydraulic cartridge.


Thanks’ to 38 clicks available, it provides a wider and more precise regulation of rebound.


It gives the possibility to preload in a simple and fast the fork, without having to remove the hydraulic cartridge from the fork.


The particular profile of the lip seal is adapted to avoid the slip-stick effect on the small movements of the shock.
