Cosmos 300 is the ideal engine for trikes, but also suitable for minimal ultralights and hang gliders, given its aeronautical characteristics. It is perfect for schools, professionals and experienced users. Its fundamental characteristics are comfort and reliability, thanks to the presence of elements such as the counter-rotating shaft, liquid cooling, and the dual-spark system. The engine has also designed for a long TBO (Time Before Overhaul). Particular attention to detail has been made, a true trademark of Vittorazi.
