Short throttle travel, fast throttle response and still the original look: short-stroke throttle rollers

The SERIE PRO short-stroke throttle rollers replace the Quick Action Twistgrip that is often required on large carburettors. The Throttle Pulleys are designed so that even a 34 mm Carburettor can be fully opened with just a quarter turn of the Throttle Grip. Throttle Pulleys were originally only developed for PX and PK models, but demand for older models quickly increased - the original look is particularly important for classic scooters. Throttle Pulleys are therefore now also available for large-frame models from the 60s/70s. They are not suitable for Vespa 125 VNA/VNB1-2 with Plate Headset Cover. The universal Cable Cam is recommended here.
