Ohlins TTX Replacement Spring: Best for Racing

Ohlins is the name synonymous with world-class racing, and their springs are designed for one purpose: podium finishes. These springs are significantly lighter than stock counterparts, which reduces unsprung weight and allows the suspension to react faster to sharp hits and stutter bumps. When you are hitting jumps at speed, that lightning-fast reaction time can be the difference between a clean landing and a swap.

These are best paired with Ohlins damping systems, but they are frequently used as a high-performance upgrade for other top-tier shocks. They are manufactured to an extreme degree of accuracy to ensure that the suspension movement is linear and free of stiction.

This is not a casual upgrade. If you are racing, chasing split-second improvements, and need a spring that responds to the most aggressive inputs possible, the TTX spring is the industry leader. It is for the serious competitor who demands world-class technology in their garage.

Pro Circuit Shock Spring: Best Value for Money

Pro Circuit has been at the forefront of motocross innovation for decades, and their shock springs offer a fantastic balance of professional performance and accessible pricing. They provide a noticeable improvement in “bottoming resistance,” which is essential for riders who are just beginning to hit larger tabletops and doubles. The steel quality is high, ensuring that the spring holds its shape even after a long season of abuse.

The real draw here is the peace of mind that comes with the Pro Circuit brand. You are getting a product developed through years of racing experience without the extreme price tag of a boutique experimental part.

This is the best choice for the dedicated rider who wants to improve their bike’s capabilities without breaking the bank. It offers a significant performance jump over stock components and provides the durability needed for heavy training sessions. If you want a dependable, high-performance spring that won’t let you down, Pro Circuit is the smart, cost-effective choice.

How to Choose the Correct Spring Rate for You

Choosing the right spring rate is more about mathematics than preference. Most manufacturers offer online charts that correlate rider weight—including gear—to the appropriate spring tension. Always factor in your weight with full riding gear, as boots, helmets, and armor can add 10-15 pounds to your total load.

If your spring is too soft, the bike will “blow through” its travel on jump landings, causing the suspension to bottom out harshly. Conversely, a spring that is too stiff will feel harsh and deflect off small bumps, making the bike feel nervous and unstable. Aim for a rate that allows for 100mm to 105mm of race sag, which is the industry standard for most modern motocross bikes.

When in doubt, always err on the slightly stiffer side if you are hitting larger jumps regularly. It is easier to adjust for a slightly stiffer feel through clickers than it is to deal with a bike that bottoms out on every impact. Check your manual or reach out to a suspension technician to confirm the specific rate for your bike’s link ratio.

Setting Your Race Sag for Aggressive Jumping

Race sag is the measurement of how much the bike settles under the weight of the rider alone. This is the most critical step in suspension tuning, as it dictates the bike’s geometry and balance. To measure it, find a helper, place the bike on a stand, and measure the distance from the axle to a fixed point on the fender.

Next, take the bike off the stand and sit on it in your full riding gear. Have your helper measure that same distance again. The difference between the two numbers is your sag; adjust the preload collar on the shock until you hit that 100-105mm range.

For aggressive jumping, maintaining the correct sag is vital because it keeps the rear tire planted and prevents the bike from “bucking” on kickers. If the sag is incorrect, the entire geometry of the bike is compromised, leading to poor handling in corners and unpredictable behavior in the air. Treat sag adjustment as a routine task before every big day at the track.

Knowing When to Replace Your Factory Springs

Springs are not permanent components; they have a finite lifespan before they lose their “free length” and compression consistency. If you notice that your bike is bottoming out much more easily than it did when it was new, the spring may have fatigued. A telltale sign of a dying spring is the need to constantly increase preload just to keep the bike at the correct ride height.

Visually inspect your springs for signs of wear, such as chips in the coating, rust, or physical deformation. Any sign of corrosion can lead to structural failure, which is a major safety hazard during a jump. Even if the spring looks fine, a heavy rider who clocks significant hours on the bike every season should consider a fresh spring every 50 to 80 hours of operation.

Do not wait for a catastrophic failure to replace your gear. If you feel like your bike has lost its “pop” or that you are constantly fighting the suspension to keep the bike level, it is time for a change. A fresh spring will breathe new life into your bike’s handling, making the track feel like a whole new environment.

Maintenance Tips for Long-Lasting Suspension

While springs are robust, they thrive in a clean, well-maintained environment. Every time you clean your bike, pay attention to the shock body and the area around the spring coils. Dirt and mud can trap moisture against the steel, leading to premature rust and microscopic pitting that weakens the metal.

Ensure that the preload collars are kept clean and greased to prevent seizing. If you notice the threads on the shock body are gritty or hard to turn, use a high-quality lubricant designed for suspension components. Avoid harsh chemical cleaners that can degrade the seals or the specialized coatings on the shock shaft itself.

Finally, keep a log of your suspension hours. Suspension is an expensive investment, and regular service—including oil changes and seal replacements—will ensure your springs last as long as possible. A well-maintained bike is a safe bike, giving you the confidence to push harder and stay out on the track longer.

Choosing the right suspension spring is an essential step in mastering your bike and enjoying your time on the track. Whether you are aiming for high-speed racing or just hitting bigger jumps for the fun of it, a properly dialed-in machine changes everything. Take the time to select the right rate, set your sag carefully, and stay on top of your maintenance so you can focus on what really matters: clearing the next gap with total confidence.
