Motorcycle Suspension: Professional Tuning and Service 

• Poor initial smoothness (stiction)
• Excessive diving under braking
• Loss of precision in the turns
• Rider fatigue
• Reducing of safety

Suspension setup is everything! Incorrectly tuned forks or shocks can ruin your riding experience more than a poorly performing engine.

• Analysis of rider weight and riding style
• Evaluation of real-world use (Motocross, Enduro, Supermoto, Street, or Track Racing)
• Fine-tuning of hydraulic damping (compression and rebound)
• Optimization of smoothness (friction reduction)
• Verification and installation of correct spring rates for the rider's weight
• Quick testing and final refinement

• Bike stability
• Traction during acceleration and braking
• Comfort over the bumps
• Rider confidence
• Safety in all riding conditions

Often, a professional revalve/tune is worth more than expensive aftermarket upgrades.

• Static Sag (Free Sag): Suspension compression under the bike's own weight.
• Dynamic Sag (Rider Sag): Suspension compression with the rider on board.

• Unbalanced bike
• Loss of grip
• Instability at speed

At Lainer, Sag adjustment is always measured and verified to the millimeter, never done by "feel."

The bike suspension is mainly composed of:
• Front Forks: Braking support and bumps absorption.
• Rear Shock Absorber: Traction control, stability and bumps absorption.

• Springs
• Specific hydraulic oil
• Calibrated pistons and shims
• Pressurized gas (Nitrogen)

Traditional forks, Upside-Down (USD) forks, linkage shock: every system has different characteristics and requires specific skills to be correctly adjusted.

Servicing is not an optional; it is essential maintenance for safety.

• Motocross / Enduro: Every 35-45 hours of use.
• Street Use: Every 10,000 km (approx. 6,000 miles) for amateurs use.
• Track / Racing Use: Every 5,000 km (approx. 3,000 miles) for racing use.

• Loss of comfort and precision
• Abnormal diving or squatting
• Poor response to external adjusters (clickers)
• Loss of smoothness (excessive friction)

• Complete disassembly
• Replacement of oil, seals, and bushings
• Inspection of internal components and accurate cleaning
• Restoration of factory tolerances and function

A serviced suspension returns to work like new (and often better).

Lainer is a specialized suspension shop, not a general mechanic who "also make suspension."

• Dedicated tools
• High-quality products
• Accurate internal processes
• Specific knowledge

Every intervention comes from a technical analysis of your problem, not from a generic price list.

• Stock suspension shows structural limits
• Original components are not serviceable (e.g., sealed units)
• The rider has specific competitive needs

However, our kits * (such as valves* or piston kits) are specifically developed to solve known deficiencies in the stock suspension, ensuring correct hydraulic function where the OEM fails. Our job is also telling you when you do NOT need to change anything and a good valving is enough.

Many claim to do suspension. We live it..

The proof of our expertise? We build the tools we use.
The wrenches, clamps, and precision tools we use to work on your suspension are designed and manufactured in-house by Lainer Suspension and sold to the best suspension tuners worldwide.

• No one will use improvised tools (which ruin nuts or scratch fork tubes).
• Every tightening and measurement is done with absolute precision instruments.
• We guarantee a repeatability of results impossible with DIY methods.
• If we wouldn't use a tool ourselves, we wouldn't sell it.

• Real Professionals: You speak with technicians, not salespeople.
• Technology: We use appropriate tools and machines.
• Measured Approach: No guessing, only data and results.
• Tailored Solutions: From the Sunday rider to the Pro racer.

Speak directly with those who disassemble, measure, and tune suspension every day.

How often should motorcycle suspension need to be serviced?
To ensure performance and safety: approximately every 35 hours for Motocross and 45 hours for Enduro. For amateur street use we recommend every 6,000 miles / 10,000 km, while for racing/track use every  3,000 miles / 5,000 km.

What is the difference between Tuning and Service?
Tuning (Revalving): Intervention on hydraulics (shims stacks), anti-frction treatments and general setting.
Service (Rebuild): Maintenance that involves disassembly, cleaning, changing oil and seals to restore efficiency.

What is the Sag and why is it important?
Sag is the measure of how much the suspension compresses under the weight of the bike and rider. It is the fundamental starting point for defining the correct geometry of the bike.

Does suspension tuning really change the ride?
Yes, radically. A correct tuning makes the bike more stable, predictable, and safer. It is a fundamental intervention for both the amateur seeking safety and the pro looking for lap times.

Is it better to Service or install a Suspension Kit?
It depends. Often a service or a custom setting (working on stock components) is enough for many riders. A kit (e.g., complete cartridges, shock or forks) is recommended when the starting base has physical limits that cannot be overcome or for those who want better materials and quality.

Is a stock suspension always bad?
No. Many stock suspension systems work very well if serviced and correctly tuned.
