AF 17/19mmreinforcedProduct descriptionCristian Mazelli is a dedicated Vespa enthusiast and he has been most active on the Italian scooter racing scene for many years. During his time as a racer he was constantly faced with material and part quality problems he deemed as unsuitable for the task in hand. To ease these bottlenecks in supply he decided to use his career-based knowledge of industrial research and development to create parts under his own name that he now markets under the ‘CRIMAZ’ logo. Beautifully detailed solutions combined with very high production quality are the results! Special nuts and washers for the crankshaft and gearbox shafts of the Vespa smallframe engine. This high-end kit from CRIMAZ allows torque values of up to 69-70Nm to be applied. -TIP : Do not forget to order a new gasket for the clutch cover (#90898500).
