that motor is set up to produce a lot

with such a over square bore/stroke..
In fact it prob not the right bore and stroke
combination for a heavy ADV bike...

wonder what ealse it will be seen in...
I would say they have other uses for it in mined..
It will have the ability to rev fast and high..

It seems like the wrong way round for a go anywhere bike, right? Thought the DRZ motor has the same ratio, which surprised me.



Maybe it's a reliability or vibration mitigation measure? Less stress with the shorter stroke? I'm really curious to r ead an in-depth feature on it.
