The piston is \u003cstrong\u003esingle ring\u003c\/strong\u003e to allow for the highest speeds; this ring is \u003cstrong\u003every thin\u003c\/strong\u003e (0.80 mm), hard-chromed and domed to further reduce friction. This piston is treated with a high \u003cstrong\u003esilicon content\u003c\/strong\u003e, giving it that distinctive matte appearance.\u003c\/div\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003eThe most \u003cstrong\u003emodified\u003c\/strong\u003e part is the exhaust outlet of the cylinder, which now comes \u003cstrong\u003epartitioned in a T-Port shape\u003c\/strong\u003e.
