The Polini Banana - also known as the "Snail," is the classic among Vespa PK 50 exhaust systems.
The Polini Banana helps tuned engines develop higher overall engine performance and allows the engine to freely breathe out at higher RPMs.
The exhaust is highly recommended for use with a DR 75 (or stronger).
The Polini Banana is also used in Vespa racing by the ESC in the single-class category.
The exhaust fits the following displacements of the Vespa PK 50 S/XL/XL2:
- 50 cc
- 75 cc
- 85 cc
- 102 cc
- 112 cc
The sportier the engine is designed, the more additional performance the Polini exhaust provides.
The racing exhaust requires registration for use on public roads.
