I will take a plunge and suggest the sexiest factory pipes I have ever seen on a bike. Because I am not the best with posting pictures on forums, maybe some could find and post a picture of a BENELLI SEI 750 I saw an article in a classic bike magazine at my library…..and I couldn’t take my eyes of this bike. This is a 70’s bike that had an inline 6 CYL with 3 chrome pipes on each side. To me this would have been the ‘pin up’ bike of the 70’s, just like the Lamborgini Countach was the pin up car of that period. Which old, or current models, have the same effect on you, for looks only?
