Pulley DIVERSE / IMPORT 80mm for Piaggio Ciao, SI, Bravo moped

The BGM Supertorque converter optimizes vehicle acceleration.
It immediately keeps the engine at its highest torque RPM, which means there is always full traction at the rear wheel. The BGM Supertorque completely replaces the factory converter and offers individual tuning to your own engine through two different settings. The matching angle of the pulley halves also results in perfect everyday suitability that protects the V-belt.
ORIGINAL CONVERTER FUNCTION
The original converter is optimized for the highest possible vehicle control. To this end, it reduces the maximum possible acceleration, even when full throttle is applied, up to approximately 30 km/h through the conservatively designed shifting behavior of the rear converter. This offers novice riders increased safety so that they can first stabilize the vehicle from a slow speed (handlebars straight, correct seating position, etc.). For ambitious riders and tuners, this means that any changes to the drive (variator, counterpressure spring) and/or the performance-determining engine components themselves (cylinder, camshaft, head, etc.) cannot be fully effective unless the converter is also changed.

BGM SUPERTORQUE CONVERTER FUNCTION
The BGM Supertorque converter immediately reaches the RPM of the highest torque and holds it without compromise to deliver the full engine power directly to the rear wheel. This allows the scooter to accelerate much better from a standstill and, with power-optimized engines, to lift the front wheel at times. Of course, you can also start normally with the Supertorque converter if you want to. A major advantage of the BGM Supertorque converter is its linear shifting behavior. This makes it much easier to tune the drive, especially on engines with increased power.

FITTING
To adapt the converter perfectly to the engine and your own needs, it offers two differently shaped milled grooves for the so-called sliding blocks. The milled grooves have different flank angles. Basically, the steeper the milling angle, the faster the converter halves can close and the faster the scooter can accelerate. Please note that the engine should have sufficiently high basic power for the strong setting. Series engines should use the flatter and therefore somewhat milder flank angle.

Sufficient time should be planned for testing and tuning. The combination possibilities when tuning the variator and converter to each other are enormous. Harmonious tuning of the weights, counterpressure spring and converter flank angle results in clearly improved acceleration behavior. Ideal for use in combination with the BGM PRO variator.

TIP: The subjective feeling of acceleration can be misleading quite quickly, among other things because of the heard engine speed. The ideal test always uses the same distance and an accelerometer (e.g. SIGMA MC1812, see accessories).

Please grease the converter before installation (sliding block and guide slot areas)
