With its Ø40mm, nothing is changed or improved. The original type aluminum cylinder has 3 intake transfers, the cylinder head is also original type, as well as the two-segment piston; the RRD team appreciated the overall finish which is excellent. The crankcases too, the aluminum used for this block is of high quality and will provide good engine cooling.
The crankshaft which equips this engine is a normal crankshaft of origin in half-masses, in bristles of 17mm for the side ignition and 20mm for the side variator. The bearings and the spy joints are obviously fitted and supplied.
The clutch is also mounted on the engine and comes with it. Also of good quality, it will provide good grip when you start / accelerate.
On the "ignition" side, the equipment is also very good and well studied. Original type, it will not give you more performance than an original but will be just as reliable.
