WebMay 8, 2007 · If the stock gearing is 10 teeth up front and 50 teeth in the back, then the front sprocket has to rotate 10 times for the rear sprocket to rotate once. Thus, the speedo gauges this and bases the speed off how quickly the front sprocket rotates. So you do a sprocket change, and now you have a 10 tooth up front, and a 40 tooth in back, now it ... WebJan 3, 2024 · How do you pick a sprocket size? Sprocket Ratios This is determined by the the number of teeth on the front sprocket, compared to the number of teeth in the rear sprocket. For example, a motorcycle with a 17-tooth front sprocket and a 45-tooth rear sprocket would have a ratio of 2.65 (45 divided by 17 = 2.65).
