The Metrakit 50cc Aluminium Cylinder Kit for 50cc bikes with a Derbi Euro 3 engine is a "Racing" kit which is, as the name suggests, built for the race track, but also for everyday use (regular maintenance necessary). Street-legal.
For racing, you should combine it with a 50cc racing exhaust, for everyday road use you can opt for a street-legal model (such as Yasuni, Conti or Ninja). We recommend a 17.5 to 21mm carburetor to go with it, again depending on the way you want to use it. We also recommend replacing your (worn down) original crankshaft with a reinforced one. Just have a look at our spare parts section.
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: Racing
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.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
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.
