Re: Hi all new to the forum

You have a 6 tooth 05T front and 54 rear and T8F 8mm chain. That sprocket is much bigger than a #25h 6 tooth so no problem, which gives you a final ratio of 9 to 1 a little to much for the weight you have. A 78 tooth rear would give you a 13 to 1 ratio, maybe a little low. A 6 to 72 is 12 to 1 which is what I would look for. Depends on how much top speed you want compared to low end torque. On my 110cc dirt bike I put a smaller front gear for more bottom end, and I can spin the rear tire out of the corners.
