CNC throttle tube for quick throttle grip

CNC machined aluminum gas tube for use with a short-stroke throttle grip and for mounting a hand brake pump when converting to a fully hydraulic Vespa disc brake.
Since the handlebars of the various Vespa models have different diameters with regard to the throttle tube guide, we offer this conversion throttle tube in 2 different versions:
A 24mm diameter is suitable for all Vespa PX handlebars as well as Sprint, Rally and all Smallframe types - a 20.8mm diameter is required for GS models, VNA, VNB, etc.
