Why Suspension Tuning Matters
Factory suspension is set up for a wide range of riders and conditions, which often means it is a compromise. Properly tuned suspension improves traction, reduces fatigue, and increases confidence. Pro Circuit specializes in aftermarket suspension parts and revalving services that tailor the bike's response to your weight, skill, and terrain. The goal is to make the bike feel planted in corners, stable on jumps, and plush over bumps.
Types of Pro Circuit Suspension Parts
Shock Absorbers
Pro Circuit offers replacement shocks as well as revalving for your existing shock. Their shock absorbers are designed to provide consistent damping and reduce fade during long rides or races. Key features include high-pressure nitrogen charging, adjustable rebound and compression, and a durable piston design. For most riders, a revalving service or a complete shock replacement will offer noticeable gains.
Fork Kits and Cartridge Kits
The front forks are equally important. Pro Circuit fork kits include new cartridges, springs, and valving to replace the stock internals. These kits allow for precise adjustability of compression and rebound. They are available for both conventional and upside-down forks. Upgrading to a cartridge kit can eliminate the vague feeling of stock forks and give you more control over front-end dive and steering.
Springs
Selecting the correct spring rate is the foundation of good suspension. Pro Circuit springs are made from high-quality silicon chromium steel, which resists sagging over time. They offer a wide range of rates for different rider weights. Many riders overlook springs, but they are the most cost-effective way to improve suspension if your current springs are too soft or too stiff.
Choosing the Right Parts for Your Riding
Rider Weight and Skill Level
Your weight determines the spring rate needed to achieve the correct sag. Pro Circuit has a spring rate chart to help you pick the right one. Novice and intermediate riders often prefer a plusher feel, while experts may want stiffer valving for aggressive riding. Consider having a professional setup if you are unsure.
Terrain and Discipline
Motocross tracks require a different setup than off-road trails. For motocross, you want a suspension that resists bottoming on landings and stays stable in whoops. For off-road, compliance over roots and rocks is key. Pro Circuit offers different valving specifications for each discipline. When ordering parts, specify your primary riding type.
Bike Make and Model
Not all suspension parts are universal. Pro Circuit makes specific kits for popular dirt bike brands like Honda, Yamaha, Kawasaki, Suzuki, KTM, Husqvarna, and others. Be sure to order the correct parts for your bike's year and model. The product descriptions usually list compatibility.
Installation and Setup
Installing springs and revalving can be done at home with basic tools if you have mechanical experience. However, for cartridge kits and shock work, it is often best to have a suspension shop perform the installation to ensure proper bleeding and shim stack alignment. After installation, set sag according to the manufacturer's recommendations. Then tune the clickers (compression and rebound) based on your feel and track conditions.
Cost and Value
Pro Circuit parts are priced competitively within the aftermarket suspension segment. Springs are the least expensive upgrade, typically $80–$120 per set. Fork cartridge kits range from $300 to $600. A full shock plus revalve can run $500–$800. While not cheap, the improvement in ride quality and lap times can be significant. Many riders consider this money well spent.
Final Recommendation
If you are looking to improve your bike's suspension, start with the correct spring rates for your weight. That alone can transform the handling. If you want more adjustability and performance, invest in a Pro Circuit fork cartridge kit and a shock revalve. For dedicated racers, a complete shock and fork package is worth it. Always consult a suspension specialist or Pro Circuit's technical support if you have questions about compatibility. Upgrading your suspension is one of the best modifications you can make for your dirt bike.
