Yes, there are a few double-250's on Youtube too. Apparently it can be done:

Making the pistons go up & down alternately (180°) can greatly reduce the vibrations, particularly if they are laterally close to each other. Similar to a flat twin (boxer, also 180°). But if the pistons are wide apart, you get another vicious vibration known as a 'rocking couple'.

Hi

Quite common then!
I particularly like the mono-shock one.

Cheers.

ETZ 502!!
