Venturi Spacer VESPTEC for original sheet metal cover with SI26 carburetor more volume under the Largeframe carburetor cover
Suitable for Vespa Largeframe models from 1957 to 2016, including PX, Rally, Sprint, Super, TS, GT, GTR, VBA, VBB and VNB.
The VESPTEC Venturi Spacer creates significantly more usable volume under the original sheet metal cover for largeframe engines with SI26 carburettors. The solution is interesting for setups where the standard carburettor space is running out but the original cover is to be retained. At the same time, the spacer improves accessibility to the carburettor jets and can be fitted without additional bolting.

Material and design

The integrated funnel is designed for 25.5 mm and has enough material all round to adapt it exactly to your own setup if required.

Practical use in everyday life
Space is often the real problem, especially with SI26 conversions under the original sheet metal cover. The Venturi Spacer not only creates the required space here, but also makes tuning easier because access to the jets is more convenient. This makes it suitable for everyday touring setups as well as for powerful large-frame engines with a near-standard look.

The design remains service-friendly, requires no additional screws and allows the classic cover solution to be retained even with a larger carburettor setup.
