The power of French bikes is in the Variator, throw this on your 103, TSM, or TSA, and you will be blasting Puchs like it is your job.
Multivar is very easy to fit and to modify. It is developed in detail and for specific applications. With a variator that features such sophistication, your moped has that extra sprint, a consistency in shifting, a greater mechanical ease at high speeds and a constancy in performance you've never experienced before with the original variator. This is what the Malossi technicians wanted to obtain.
