The IAME biconic spring is specially designed to connect the exhaust manifold and the relaxing pot on the motorizations X30 and KA100. Its "biconic" shape (wider at the ends only at the ends) is not aesthetic: it allows a uniform distribution of the voltage and a better absorption of the high frequency vibrations specific to the 2-time competition engines.

Made in high carbon steel, this spring retains its elastic properties even when subjected to the extreme temperatures of the exhaust outlet.

- Why choose the iame biconic spring?

1. Quality Origin: Iame certified piece, ensuring a perfectly calibrated length and voltage to not crush the joints while avoiding leaks.

2. Thermal resistance: Specific treatment of metal to prevent heat with heat (annealing phenomenon).

3. Increased longevity: Its biconic form limits internal friction points, thus reducing the risk of mechanical fatigue breakage.

4. Versatility: Compatible with the flagship motorizations of the brand, of the X30 (Junior / Senior) to Ka100.

💡 Michel's trick

"The exhaust spring is the room that saves your session! My Pro Council: never goes up 'to dryness'. The trick: put a small hazelnut copper grease (High temperature) on the spring brackets before installing them. It avoids that the spring does not wear out by friction against the eyelets of the pot and it greatly facilitates disassembly. A Last Tip: If you see that a spring begins to vibrate or mark the metal, change it. A loose spring in the race, it's a black technical flag! "

- Mounting & Security Guide

• Tool: Use a tire spring For installation to avoid hurting or distorting brackets.

• Safety: On the X30 engines, it is strongly recommended to use Spring protectors (Silicone sheath) To prevent case of breakage, the piece of metal does not end on the track or in a tire.

• Verification: Check the voltage after each session. A spring must be firm; If it "floats", its effectiveness is zero.

❓ FAQ SEO (Frequently Asked Questions)

Q: How many springs should be for an exhaust x30? A: It usually takes two to ensure uniform pressure between the collector and the pot.

Q: Why do my springs often break? A: Often because of a misalignment between the pot and the engine, or because of the absence of grease on the contact points that creates abrasion wear.
