Description

SERIE PRO short stroke throttle pulley adapter, steering tube, for Vespa 125 VNB3-6/150 VB1/VBA/VBB/VGLA-B/T3/T4/GS VS2-5/160 GS aluminium, with cable fixing plate. ATTENTION: the PX throttle pulley will still be required The SERIES PRO throttle valve rollers replace the necessary quick-action knob in the case of large carburettors. The throttle valve rollers are designed so that a 34 mm carburettor can also be opened with a quarter turn of the throttle knob. Initially, the throttle rollers were designed for PX and PK models, but demand for older models rose very quickly, as with our "old ladies", where the original look plays an important role. Throttle rollers are now available for 1960s/1970s large frame models. The throttle valve rollers do not fit Vespa 125 VNA/VNB1-2 models with sheet metal steering head cover.
