Description
Airsal 150cc Aluminium Cylinder Kit Sym 125cc 4-stroke. It is made of aluminium, diameter is 61mm for a 57.8mm stroke => exactly 150cc.
Intended to be used with original cylinder head, the kit makes for slightly more power and definitely more torque. To be more specific, the difference will be mostly noticed in better acceleration, a better take-off and slightly higher top speed..
To get the most out of this kit, we recommend running it with a sports exhaust and a racing variator (such as Malossi Multivar etc.). Now that you pushed your engine from 125cc to 150cc you can expect a boost of about 2 to 3hp.
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.
