Outside of being hideously ugly, there is no benefit. In fact the closing flap, which has no use but visual affect, makes it less reliable than other stage 1 air cleaners.
I have ran them on my bikes before. Besides looking cool they dont do much. An you would prolly gain more preformance with another choice of air filter.
1995 just called. they want their air cleaner back
Haha - I was going to say something like that. Although I loved the look of the 90's bikes with hyperchargers, this new one looks like crap to me anyway
