Most maintenance on the motor of your Vespa requires the use of special tools and adapters. Without their use a quick and professional service without permanently damaging engine components is virtually impossible. Regrettably, many of these exclusively Vespa devices are no longer in production or indeed available, apart from a few parts of dubious quality and origin.
Hardly anything can be as annoying, while working on your Vespa, than poor quality tools. For this reason we have had the complete range reproduced and also in some cases even redesigned. Our SIP tools and adapters are precisely manufactured using the highest quality, genuine tooling grade steel, with some items also being surface treated for extra durability
The SIP castle-nut tool is necessary for attachment and removal of the castle-nut that is used to secure the front wheel bearing in all smallframe models. Over the years a number of different castellated patterns were used while producing these nuts. This lead us to design this tool to be compatible with all the different types of castle nuts used by PIAGGIO to secure the bearing, whatever their size.
