What are the dimentions of a BMW R75 5 battery?

R75/5 has 2 types, a bigger, and a smaller battery, depending on the space available. The bigger one is a DIN 52515 12V 25Ah 130 A lxdxh= approx 185x130x170mm the plus is on the right, when battery is seen from the front side. the smaller battery will then be 185 x??x170mm Also consider that you might use a battery smaller than this. A Yuasa 51814 will fit and it's cheap.
