Stage6 Contra Springs

Stage6 torque springs for Minarelli 2-stroke engines, ideal for fine-tuning variator behavior and optimizing shift performance.

Choose the right spring stiffness
Stage6 offers black-coated torque springs in multiple stiffness levels. Proper belt tension is essential — if the spring is too soft, the belt slips; too stiff, and the belt can’t travel correctly. In both cases, overall engine performance suffers. A stiffer spring isn’t always better: an overly hard spring can prevent the engine from reaching its ideal RPM range.

Manufactured from carbon-silicon spring steel, heat-treated, and coated for durability and reduced wear.
