High-quality aluminium cylinder with excellent heat dissipation and a durable Nikasil-coated bore for superior wear resistance.
The cylinder has 6 precisely machined transfer ports and a large exhaust port with boost ports. This design ensures excellent gas flow and scavenging, providing strong performance in the mid and high rpm range.
The cylinder comes with with a particularly low-friction graphite piston (1-ring). Also included is a cylinder head with large cooling fins for optimum cooling (incl. O-ring).

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.
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.
