Athena offers the widest range of replacement engine gaskets available on the market, boasting over 40 years of experience in the industry.
At the core of Athena gasket kits are solid know-how, constant technological development conducted by an internal team of engineers and designers, and production carried out in strict compliance with the stringent parameters imposed by manufacturers. The use of state-of-the-art lasers ensures perfect cutting quality.
Furthermore, Athena has a wide availability of raw materials, performs surface treatments to compensate for surface irregularities, and follows material relaxation processes to improve sealing in the most critical areas.
This complete and unified gasket series for Vespa Large Frame is designed for all Vespa enthusiasts who want to overhaul their vehicle's engine with safe, cutting-edge products that offer several advantages:
BYE BYE SILICONE
No oil leaks, no silicone residues to clean up, speed and ease of installation: Athena gaskets do not require sealants.
UNIQUE ON THE MARKET
Since the 1950s, the engine blocks installed on different versions of Vespa Large Frame have changed in geometry, sometimes for a few but decisive details.
Athena has deployed its technicians and over 40 years of know-how to study the original

The Dell'orto SI carburetor series features a cylindrical venturi duct. 

This very simple shape to produce during manufacturing, however, performs less well in operation compared to carburetors with a conical frustum-shaped venturi duct, as it generates turbulence.

The venturi cone made by Sil-tech PERFORMANCE is designed to address this issue.
Thanks to many CFD (computational fluid dynamics) simulations conducted to derive the best cone profile and various tests performed on the respective motorcycles, a solution has been reached that allows solving the problem of inlet turbulence by developing a specific object for each application.

With the application of a venturi cone, the flow enters less turbulently, achieving a greater air flow entering the engine and an improvement in performance across the entire RPM range.

Designed to occupy as little volume as possible, ensuring optimal operation within the original carburetor box.

TO INSTALL THIS COMPONENT, IT IS NECESSARY TO REMOVE THE ORIGINAL FILTER ELEMENT. 

Material: sintered NYLON PA12, ensures chemical resistance to solvents (gasoline and other hydrocarbons) and oils.
