Calibrated punch SIP steering ring nuts (upper steering head (upper inner steering head bearing disassembly), for VESPA all models also suitable for GILERA/PIAGGIO all Models Most maintenance on the engine 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. Unfortunately, many of these devices exclusively for VESPA are no longer in production or actually available, apart from some parts of dubious quality and origin. There is nothing to be more annoying, while working on for VESPA, than poor quality tools. For this reason we have had the complete range reproduced and even in some cases even redesigned. Our SIP tools and adapters are precisely crafted from the highest quality, genuine tool grade steel, with some items even being surface treated for extra durability Without properly sized steering knuckle bearing and new bearing removal tools they can be easily damaged during renovation. These tools are produced exactly to the dimensions originally requested.
