Forced-air type air box boosts intake performance

The 1994 model OWF9 was the machine that L. Cadalora rode to rank 2nd in that year's GP500 series with wins at the U.S. GP and the Europe GP (Barcelona). A review of power development characteristics and rigidity balance led to the adoption of a panel stock aluminum frame to replace the extruded aluminum frame of the previous year's model. Development efforts to improve the aerodynamic characteristics led to a cowl design that shifted the air intake mouth toward the inside. To improve intake efficiency on the '95 model, a forced-air (ram-air) function for the air box produced at Yamaha's London R&D base, Activa, was adopted.
