The factory motorcycle with which Jean Michel Hervé rode 24 hours in Bold´Or. He placed in the category in 3rd place. The motorcycle was ridden in 1971 and then rode the French championship for another 3 years. Subsequently, it was modified a lot and then sold out. After 2 years of effort and searching, we managed to put most of the machine as M. Hervé rode it together. 4 factory pieces were made.

This differs from the other 3 in several details due to the fact that he spent his life abroad from the beginning. B. Stasa, K. Bojer, J. Král and others rode a motorcycle with us.
