The final version of the design came in 1990 with the 907IE (Iniezione Elettronica); now without the name "Paso". The engine remained liquid-cooled and the carburetor was replaced by the most modern Weber-Marelli IAW 043 system that integrated ignition and electronic fuel injection, which transformed the rideability of the bike. Power increased to 90 hp and top speed to 230 km/h. The wheels were changed to 17 inches, giving the bike more stability.
Despite these advances sales of this model remained sluggish, and when production ceased in 1992 only 2,303 907IE's had been built.
