In the 2-stroke market sector, SITOPLUS is our most sophisticated product, with its unique blend of quality and overall performance. This is a new range of systems for the most popular scooters and mopeds available on the European market. Although identical in external appearance to the OEM system, their internals have been completely redesigned so as to provide improved performance, particularly in the critical lower and middle range of the engine. The result is a noticeable improvement in flexibility and acceleration, with enhanced fuel economy and reduced emissions. Best of all, the SITOPLUS range satisfies current legislation, and these systems are homologated for normal road use. See also this website.
