A typical sign: the engine revs high, but the scooter doesn’t accelerate.Each spring’s strength is printed directly on it, making them easy to tell apart. The spring always needs to match the engine setup — stiffer doesn't automatically mean better. A spring that’s too hard can actually prevent the engine from reaching max RPM.Made from heat-treated, carbon-silicon spring steel and finished with a black coating for reduced wear and increased durability.Stage6 Torque Spring SpecsDimensions: 4.3 x 58.1 mmStiffness: SoftFits: Piaggio and GY6 4-stroke engines
