Adapter Conversion Kit: Crankshaft 19 mm to 20 mm Cone -FRT- Vespa V50, PV125, ET3, PK50/80/125

FRT Adapter Conversion Kit: Crankshaft 19 mm to 20 mm Cone

The FRT Adapter Conversion Kit allows a Vespa Smallframe crankshaft with a 19-mm cone to be adapted to the geometry of a 20-mm cone version.

This is particularly useful for engine builds where an existing 19-mm crankshaft is to be reused, but components designed for the larger 20-mm cone are to be used.

• Conversion from 19 mm to 20 mm crankshaft cone
• for Vespa Smallframe
• Compact adapter set
• Ideal for conversions and combinations of different crankshaft and ignition configurations

Precise adaptation of the crankshaft cone

The adapter sleeve is mounted on the existing 19-mm cone and creates the mounting required for the 20-mm version. This allows the existing crankshaft to continue to be used in corresponding conversions without having to switch to a different shaft solely for the larger cone version.
