MALOSSI CONTRA SPRING (RED) 5K RPM (UNIVERSAL)

Malossi Red Contra Spring

Example Product

• Malossi Red Contra Spring (+35 %) — A high-stiffness torque spring used in many CVT / scooter engines.

Key Characteristics:

• Stiffness / Load:

  • According to Malossi , the red spring is ~35% stiffer than the OEM / stock contra spring. 

• Material & Build:

  • Made from silicon‑steel with high carbon content, pre‑tempered for strength.

  • Heat‑resistant coating / paint on the spring ensures durability under high thermal stress. 

• Tuning Purpose:

  • Intended for tuned or modified CVT setups where belt slippage is an issue or when more “pull” is required. 

  • A stiffer contra spring holds the belt tighter on the pulley, which helps maintain tension during acceleration or high load. 

  • Because it resists outward belt travel more, it can make the engine rev higher / stay in the “power band” longer during CVT ratio changes.
