The crankshaft has a special shape to reduce turbulences inside the crankcase. It has a black coating to reduce the wear on the crankshaft. The front part was extended to improve the seal against fuel leaking.

The sleeve has 7 transfer ports and an exhaust with booster ports. The special shape and positioning of the ports, covered by a patent, improve the internal fluid-dynamics to obtain the maximum possible performance.

The cooling heads of the PLUS 2 engines are made lighter by making aditional holes in the cooling fins.
This reduces the overall mass of the engine.

The combustion chamber is supported by an O-Ring which is placed between the combustion chamber and the crankcase to reduce the vibrations of the combustion chamber.
