This Polini Primary Transmission 24/61 helical Vespa 125cc PK / Primavera to change the gear ratio of your transmission.
Higher or lower gear ratio might be the deciding factor in how your scooter will perform. A higher ratio (shorter transmission) will make the engine reach maximum horsepower more quickly, meaning acceleration will be improved, sacrificing a bit of top speed. A lower gear ratio (longer transmission) has the opposite effect - higher top speed and slower acceleration.
This is a complete transmission with 24 / 61 gear ratio.
- reinforced primary transmission
- gear ratio 24 / 61
