Opening rocker arm 1199 F18 key-ring
This opening rocker arm was mounted on a Ducati 1199 F18 that competed in the WorldSBK 2018. Opening rocker arms actuate the opening movement of the valve. The intake camshaft lobe acts on the upper curve of the rocker arm, while the lower curve drives the opening shim and opens the valve.
Made from heat-treated steel, they then undergo a nitriding process to maximise surface hardness. Subsequently they receive a special diamond-like carbon coating, which combines extreme hardness and low friction resulting in ultimate abrasion resistance. Rocker arms are subject to a maximum acceleration which can reach as much as 34,000 m/s2. Weighing just 20 g (.7 oz.), these components are small, yet extremely durable.
As this component is subject to oxidation, we advise frequent lubrication to maintain its appearance.
