Honda NSR 500 4 Cylinders (1984~1989)

This bike, first presented in March 1984, has so many different versions of it that it would be impossible for me to find all configs and pictures of this bike.  But mainly, it started with a V4 @ 90° with the gas tank under the engine to finish with a conventional frame and a 112° V4.  Basiacally, the first V4 still have the colors of HRC (white, red, blue) while the following versions have the typical blue / white colors of their sponsor, Rothmans.
