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.

Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
