Here is a Malossi variator for the Vespa ET4 150.
One of the best enhancements you can make on an automatic scooter is the installation of a new, improved Malossi Multivar variator. Adding an after-market Malossi Multivar variator ensures a smooth start-up, "seamless" automatic shifting, improved high speed idle and a consistant driving high-performance. Additionally, tailoring the roller weights results in improved acceleration and a slightly higher top speed.
This variator for the Vespa ET4 150 contains all parts of the variator assembly, including pressure spring, slides, roller weights, pressure plate, and drive face.
