The SIP degree wheel adapter is an essential tool for accurate ignition timing adjustment on a wide range of Vespa models. Designed for engines with an M11x1.5 thread, this adapter allows correct and stable mounting of a SIP degree wheel during timing and measurement procedures.
Thanks to its precise fit, the adapter is ideal for finding top dead center (TDC) and accurately setting the ignition timing. A perfect addition to SIP measuring and tuning tools, suitable for both enthusiasts and professional mechanics.
