Description
Andrea Pinasco was one of the first mechanics who successfully tried to improve the performance of classic Vespa scooters, and his company Pinasco consequently became one of the household names for Vespa tuning. Cylinders, intake manifolds, exhausts, air filters, carburetors, crankshafts and more - everything you need to boost the performance of your Vespa.
The Pinasco Cylinder Kit 177cc aluminium 57mm stroke Vespa GTR / Sprint 125-150cc is a replica of the classic 177cc racing cylinder by Pinasco. It is an aluminium 'Big Bore' (63mm) cylinder that will increase displacement up to 177cc while allowing to retain the original crankshaft. This top quality cylinder is a performance part with very convincing output throughout the entire rpm range, with more power and awesome torque even at lower rpms.
Though made of aluminium (with Nikasil coating), it is extremely robust and low-maintenance. It comes with a 2-ring piston and an original Pinasco cylinder head with central spark plug. Easy to mount, plug and play. We recommend checking the condition of your crankshaft and bearings before mounting. The cylinder lends itself to additional tuning measures - we recommend a larger carburetor and a tuning intake system. Also recommended - a reinforced crankshaft, e.g. the Pinasco crankshaft with 57mm stroke.

How to Install a cylinder on a scooter, motorcycle or moped
The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.
The service life of a cylinder depends on whether it has been fitted correctly.
Tuning Level: Sport
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
How to run in an aluminium cylinder?
Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
