A special interest goes to the DLC coating technology which will increase the lifespan of the rotating parts, especially in the piston-area where the pin is exposed to high pressure from both piston and conrod. The crankshaft itself will resist better against wear on the conrod area but also at the intake area where sometimes dust passes.
