HONDA RA 616H
The engine air supply system features three ducts. Starting from the airbox, two pipes split under the engine cover: one (coloured in dark blue) is channeling air to the compressor, while the other (in yellow) is feeding an ERS cooler. A third tube (in light blue) stems from the aperture located under the main roll hoop inlet and behind the driver’s helmet. In order to circumvent the engine air supply duct, it branches off into two pipes that feed cooling air to the oil cooler.
