Qualitatively very convincing cast cylinder made of a Minachrome grey cast iron alloy. The 50 cc version offers remarkable performance results compared to the standard cylinder, considering that the displacement has not been increased. One of the reasons for this is the High Compression head.

The cylinder can still be driven with the original components, only the carburettor should be refitted (main jet 5-10% larger).

In terms of durability, the Trophy is on the same level as the standard cylinder and so thousands of kilometres of worry-free driving are guaranteed.
