Based on the name and the colouring, it would seem that the design was influenced by the famous Martini Racing livery, which won a number of Le Mans titles with Porsche.
Other than the new colour scheme, there are no reported changes to the EVO AM with the Le Mans edition.
In our helmet shootout, we found that the 661 EVO AM comes with decent padding and fits comfortably on the head. The retention system was also a highlight, as it felt secure and adjusted without hassle. See the full review in Part 1 of our helmet shootout (Part 2 of the shootout can be found here).
The Le Mans 661 EVO AM will be available in South Africa next year through your local 661 retailer.
