Genuine Aprilia motorcycle part Valve Stem Seal, part number AP0230510, item 18 in the diagram. These are a direct replacement for the ones fitted in the factory.

Valve stem seals provide a defined metering rate of oil to the valve stem interface of the internal combustion engine to lubricate the valve guide and minimize engine emissions. Over time and with continued hard usage, they can deteriorate and become ineffective and the blue-white exhaust smoke will last longer after start-up and acceleration.
