Cast iron cylinders with a processing on a good level and throughout with the quality of the series cylinder to compare.
The cylinders of the company D.R. (Diffusione Ricambi) enjoy a very good reputation. Already in the shift scooter sector DR has developed powerful cylinders with a long service life at a reasonable price. So one can almost make a general recommendation for the automatic sector for those who want to make their scooter faster without much effort.
The DR differs from its series counterpart by modified control times and above all by larger channel widths, especially the overflow valve. The DR philosophy is to give the cylinders a wide speed band with lots of torque from the lower speed range. This makes the DRs also interesting for tuning mufflers, so there is not much effort required.
The DRs respond very well to further -after-treatment - by a suitable exhaust and carburetor. In this way, the performance is again significantly increased without any loss of reliability.
The cylinder is supplied with all necessary small parts and gaskets.
