The Ripon II's nose enclosed a 570-horsepower Napier Lion engine in fitted cowlings. Removing the earlier nose-mounted radiator and its shutters gave the nose a pointed profile. The spinner of a larger two-bladed wooden airscrew emphasized that shape. Cooling came from quadrant-shaped retractable radiators behind the engine bay, which the pilot could extend from both sides of the fuselage.

The Ripon II was so extensively revised around its engine and cooling system that it barely resembled the earlier Ripon I.
