This was taken @ Olgebay Park in Wheeling, West Virginia. When I bought the bike it had a 15 tooth sprocket on it. Not sure why, because factory says it should have been a 16 tooth. I bought a 17 tooth, not knowing about the 15 tooth on it, and what a world of difference it made on the highway. I did lose bottom end though. So I recently have put a 16 tooth on it and I seem to like it the best!
