17 tooth will replace the stock one, a 15 tooth i like because it gives you a little more low end power and you dont loose much top end. I went with a 15 tooth bell because the tires i have on it are a little bigger than the stock ones so i wanted to keep low end. 2 teeth is not a big difference. the lower the teeth the more low end power but you loose high end, the more teeth the more top end but the lower end will not be so great.
