1985 Type: GR71G code : F

The GSX-R750F was introduced into the market in March 1985. Its philosophy focused mainly on the weight loss. The bike also showed the new TSCC (twin swirl combustion chamber) cylinder head, and the DAIS (direct air intake system).
The chassis was a multi-rib extrusion molded aluminum box section piping and cold-cast aluminum alloy components, the MR-ALBOX frame. Dual lights come from the Endurance theme race. The first version is very peculiar for the grid cover on the exhaust.
