The ''660'' engine incorporates a five-valve cylinder-head. There are three intake and two exhaust valves. The theory is that the smaller valves have a larger area at a lower weight than a four valve system and allow maximum intake flow and velocity.

The fuel system incorporates one slide carb and one butterfly carb. These are operated sequentially by a manually adjustable system.
