I just recently got my old 1981 Honda atc 200 going. I remember now putting a smaller front sprocket on it back in the 80’s for towing trailer and just to make it slower in the rough terrain ( I think it was a 9 tooth?). I wont be using it for that anymore so was going to look for the original gear sprocket (11 tooth?) Its just to slow now for what I will be doing with it. Instead of gearing back up, are there larger tires available bigger than the 25" to fit on 9" wheels? I need new tires anyway. It would give more ground clearance and also bring the gearing up. Or, any other larger wheels that would fit. Maybe even newer wheel hubs and wheels that would fit on the original axle?
I’m just researching some possibility’s. I could just change the gearing back.
