Later versions of the Bristol Titan also used a Farman-style reduction gear produced by Gnome-Rhône.

The engine was designed as a five-cylinder radial, to use as many parts of the Bristol Jupiter as possible.

Cylinders, pistons, articulated connecting rods, crankshaft and other minor parts were interchangeable with the Jupiter.

With the introduction of the K-series, Gnome-Rhône finally ended royalty payments to Bristol, the Gnome-Rhône 5K being built in much greater numbers than the original Bristol Titan.

By 1930 they had delivered 6,000 Jupiters, Mistrals and Titans, making them the largest engine company in France.
