Product description
Cristian 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! These primary-drive cogs by CRIMAZ for the Vespa smallframe engines have been designed including an exclusive feature. They are pressed into position over a conical shaft, enabling them to transmit more power than the original set up. CRIMAZ recommends they be tightened to between 60/70 Nm
