firstly what does fp stand for???
and dont most pro supermoto riders use akrapovic
i think the top berg rider in S1 uses a twin titanium akrapovic system
Depends on which bike you're referring to. However, by far the most popular choice in the UK for the berg is the FP - very good power and less money than the Akro.
Akros have been a bit more popular because it seems to have been difficult to get hold of the FP this year.
