Why more expensive than a car battery?
A couple of guesses.
It costs a certain number of dollars to run a factory/ production line.
IF there isnt sufficient demand to run that production enough, then in order to pay for the equipment & maintenance, they have to charge more per unit manufactured. Given sufficient demand, they could get the price down, unless the demand crested an amount that required more new equipment, space, etc.
Point is, if demand is quite a bit less than production capacity, each item is often more, just to keep the business afloat.
Tolerances. Making a motorcycle battery must surely require manufacturing at, not only closer tolerances, but the plates must be thinner, yet, these batteries have to be able to handle the vibration & rough ride a bike delivers. I suspect there are supports for the plates built into the case that dont exist on automotive batteries.
I wouldnt be surprised to find that M/C battery manufacturers are required to build a battery that doesnt go dumping fluid just because the bike got dropped. & the battery needs to survive that bump, too.
