The original front sprocket is 13T. Combined with the 49T original rear sprocket, this bike excels in tight, steep, and technical off road situations and gears are close ratio since it is geared down so much. But that is the intended market! Makes sense.
I did go with 14T front, but that DOES required grinding a shield down. I will take a picture when I have a chance. I was concerned about keeping the area clean, but the sprocket cover has additional shrouding, so it's OK. I think this will be the same in the new 172-FMM-5 engine, but I might rethink the gearing now that I've ridden it. It has the power to pull 70+, but even my Tusk Dsport beast on the Storm is a smoother road tire!
