Pinion kit for racing fitting Z16

Lightweight steel and Ergal

Component to set up a final racing transmission kit with a combination of: - Regina Racing chain ORNV6W 520 pitch, used by the main Superstock teams - ergal sprocket with hard anodizing (from 40 to 42 teeth) - lightened steel pinion (from 15 to 16 teeth). FOR RACE USE ONLY. The installation of the following possible combinations allows to reduce the rotating masses, improving the acceleration. All components are lighter than their standard components and the entire kit saves 850g: - 40-tooth sprocket and 16-tooth pinion (2,500 ratio) - 42-tooth sprocket and 16-tooth sprocket (2,625 ratio) - 40-tooth sprocket and 15-tooth pinion (2.677 ratio) - 42-tooth sprocket and 15-tooth pinion (2.800 ratio). Attention: the combination requires the 520 chain racing chain, sprocket and pinion can not be used with the standard chain or with a standard sprocket or pinion. It is recommended that the transmission get replaced when the 4,000 km are reached and, in any case, in the event of excessive wear, depending on the style and driving conditions
