The NARAKU piston has a molybdenum coating to reduce wear and shorten the break-in period. This piston has been included in all 50cc NARAKU cylinder sets since 2009 and can also be used as a replacement piston in original Chinese cylinders without any problems. The CNC turned grooves in the piston skirt provide permanent lubrication. The lubricating oil hole with recessed oil groove in the area of the piston pin bearing was taken from racing. Mature piston technology for 4-stroke engines
.The piston set is supplied complete with piston rings, oil wipers, piston pins and piston retaining clips.
