Things with wheels that are cool
To direct air to the back sides of the cylinders for more even cooling!
Oops...I forgot to include "and center" ; i.e. the scoop directs air to the rear and the center cylinder for more even cooling. The center cylinder gets much hotter on a triple than the outer ones.Its actually a very good idea that I believe Suzuki 'borrowed' from some Triumph Trident and BSA racebikes. Which of course Chevrolet had a functionally similar setup on the Corvair that directed forced air from the fan...
Partly to cool the cylinder head, partly to look tough.
