If you are contemplating buying the special hollow bolt from Piaggio or other sources bear in mind that it is very easy to get the grease in once you have removed the standard bolt. If you have an ordinary grease gun all you need is a tapered adapter or even a rubber coupling. I used an old nozzle from a tube of silicon sealant. Very little pressure is require and you can keep on pumping until the grease comes out of the upper and lower bearings.
