Woodruff Key primary gear cog CRIMAZ

steel, hardenedProduct 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! Very high-tensile woodruff keys, made from c70 grade tempered steel by CRIMAZ. The thickness of the woodruff keys is increased slightly (0.01-0.02mm) to compensate for manufacturing tolerances. To guarantee a perfect fit it is recommended to check the clearances carefully during mounting in case modifications are necessary. OEM numbers (for comparisons):000267 – 000103 (PIAGGIO)
