Cast iron cylinder kit with a very high level of craftsmanship and a quality that matches in every point that of the original parts.
The cylinder kits of Diffusione Ricambi do have a very good reputation for their lusty power and the very high reliability.
The port timings are optimized and the port areas, especially those of the transfers, are much bigger. This makes the cylinders very strong pulling with a nice punch at lower and mid range revs. Especially the 70cc version.
The kits do respond very well to enlarged carbs and well suited exhausts. So the power is increased once again without loosening the outstanding reliability.
