After the success of the first aluminum thermal unit for Vespa "Farobasso", Pinasco continued development in this field and is now pleased to present the new 160cc thermal unit for Vespa "Farobasso" / 5% cylinder reed valve. Perfectly
interchangeable with the original thermal unit, it keeps the aesthetics unchanged and substantially increases the vehicle's performance. Thanks to the reed valve intake, the "rejection" problems of classic "Piston Port" are eliminated, making the engine even more fun and enjoyable to ride. The power and torque increase
even further compared to the previous cylinder while maintaining reliability. The Pinasco 160cc Reed Valve thermal unit brings all Vespa 5% into modernity while retaining all the original components.

Attention: when using VM / VN / ACMA engine cases, the piston skirt must be shortened by approx. 3-4mm.

Recessed head with silicone Oring gasket and 8 cylinder mounting points
Steel exhaust manifold with silicone Oring gasket fixed to the cylinder with specific bracket and 4 screws
The cylinder features a sleeve of about 8mm that allows proper piston guidance even if mounted in 62 and 64 mm stroke
The sleeve has a larger external diameter compared to original cylinders
and requires boring the casing inlet to 76mm for 8mm
depth.
To perform this operation manually, a steel base/guide is provided to screw onto the casings
Simply perform the work with a cylindrical cutter

Meteor Piston

The BGM 200cc cylinder is an improved version of the already reliable and powerful original cylinder. Suitable for 200cc engines of the Rally200, PX200, Cosa200, and the Spanish models DS/DN/TX/Iris, the BGM cylinder offers an additional advantage in terms of safety and performance thanks to an exact honing of 9/100 operating distance and slightly larger transfer ports. This makes it slightly more powerful and more fuel-efficient compared to the original.
 

The original head can be used, ready for installation with pistons, clips, piston pins, and base gasket.
