The 60ah batteries are a better deal, if your motorcycle ends up using 150 watt hours per mile (high end of what people use, like if they are going fast) then you will get around 20 miles range with the 40ah pack and 30 mile range with the 60ah pack, assuming you are going slower (less then 65mph) then you will get more miles per watt hour, some people say as many as 75watt hours per mile, so your range at say 45mph might be 40 miles with the small pack or 60 with the large pack.
at $55 per 40ah battery or $79 per 60ah battery, the large one is the better deal.

23 cells is an odd number...

Your weight per watt hour of battery is also going to be better with the larger cells.
