SIP continue their mission to make hard-to-find small components for vintage scooters and to upgrade them where possible.
SIP Quick Throttle Disc gives quick action to a vintage Vespa headset.
SIP have designed a range of CNC aluminium throttle and gear cable pulleys (‘wheels’ ‘rollers’ or ‘rolls’ as the Germans nickname them).
They have various types to fit most older model Vespa largeframes and some smallframe models as well.
The throttle rollers are interesting because with a slightly larger diameter you can get a ‘quick action’ effect which opens larger carburettors without having to spin around the throttle grip like a Russian gymnast.

Prices range from €14.90 – €25
