Pro-tek Made For Ducati 916 SPS Sport and similar items

This Pro-tek 520 Pitch (1/4" chain roller width) 14 tooth front sprocket is completely CNC machined to exact tolerances from 4140 nickel-chromoly steel resulting in accurate tooth profiles. This comes in 2 sizes - 14T 15T This is Not gear-hobbed like other sprockets insuring the teeth fit precisely on the chain rollers insuring maximum chain/sprocket life along with a more efficient power transmission. It is lightened with drilled holes to save on rotating mass. Every lb of rotating mass equates to a 4 lb weight reduction. It is case hardened to Rc 58-60 and finished with a silver zinc plating for added durability/protection from corrosion. This sprocket has a flat side (engraved) and a large offset side as shown in photos. It is brand new made in the US from Pro-tek, a leader in the industry for over 25 years. Applications NOTE:This is a 520 pitch conversion sprocket which requires both 520 pitch sprockets and 520 pitch chain. The stock setup is a thicker 525 pitch chain and sprockets: 1994-2000 Made for Ducati 916 Sport Production 15T Front/36T Rear Stock, 525-94 Stock Chain 1994-2000 Made for Ducati 916 Strada Biposto 15T Front/36T Rear Stock, 525-94 Stock Chain The gear ratio is ratio of teeth between front rear sprockets. This determines how engine RPM translates into wheel speed. Changing sprocket sizes, front or rear, changes this ratio changing the way bike puts power to the ground. With respect to stock gearing, installing a smaller front sprocket (fewer teeth), or a larger rear sprocket (more teeth), provides a lower gear ratio increasing acceleration but decreasing top speed. Conversely, installing a larger front or smaller rear provides a higher ratio which decreases the acceleration but increases top speed. Every 1 tooth change in the front is equal to a 3 tooth change in the rear. So a rear change more than 2 teeth means adding/removing chain links.
