Thermal groups for Vespa and parts
When we talk about Vespa, we cannot help but mention one of the key elements that defines its performance: the engine group. This component, essential for the functioning of the engine, includes the cylinder and the piston, which work together to ensure that every drop of fuel is transformed into power and speed.
If you are a scooter enthusiast, you know how important it is to have an efficient engine group. It not only affects the overall performance of your vehicle but also impacts its reliability over time. Vespa engine groups are designed to withstand wear and tear, thanks to high-quality materials and robust construction, ensuring excellent durability over time.

The Pinasco 102cc SRV "Zuerino" Ø 55mm thermal group is a new product dedicated to the world of Vespa 50 and Ape 50 with a 43mm stroke. Based on the famous Zuera 135cc, the 102cc SRV "Zuerino" features a transfer system very similar to that of its bigger brother, using the same RD350-type reed valve pack and the same flow guide, it mounts a single-ring piston with bi-conical pin, the new central spark plug head with 8 studs and centering bushings that definitively eliminates the problem of leaks and consequent performance drops with a compression ratio of 12.3:1.
The Pinasco 102cc SRV is a generous engine designed to make the most of power at low revs, its exhaust port has been designed to work correctly with original exhausts and commonly called "banana" stamped exhausts but can also be used in more advanced setups.

The 225cc aluminum thermal group with Nikasil treatment is the kit that was missing for fans of the Vespa GS160 and SS180. Perfectly interchangeable with the original, it has a solid aluminum manifold with a reed valve admission that allows the installation of the original carburetor or the classic SI carburetor up to a diameter of 28mm. Torque and maximum power improve significantly, only the enlarged exhaust requires modification of the original muffler manifold or replacement with the high-performance Pinasco Touring for Vespa PX 200 art. 25560824.

Enhancing the thermal group of your Vespa doesn't just mean increasing power; it also means improving the riding experience. With a properly upgraded thermal group, you can achieve greater acceleration and a higher top speed, turning every trip into an exciting adventure.
Increasing Displacement: Increasing the engine's displacement is one of the most common modifications. For example, upgrading from a 125cc cylinder to a 177cc one can lead to a significant performance boost.
Cylinder Replacement: Aftermarket cylinders are designed to offer superior performance. Brands like Polini and Malossi offer high-quality cylinders that ensure power and reliability. Consider also replacing the exhaust
