Ie; = - = not = | = I know that Moto Guzzi runs theirs that way but don't they have to add counter-rotating mass to make it work? Won't this cause handling issues on a "sport" tourer?

The engine will try to twist the bike over to the side when the crankshaft is accelerating. I've heard Guzzis aren't great about it, but at the same time I haven't heard many complaints about BMW's boxer engined bikes which should do the same thing.

Is it because the boxer engine is "flat", directly opposing?...or do they have "counter-rotating shafts" to balance this out? Oh and that was my point basically, I'm am NOT an engineer by any means but I can see the engine in my Mustang jump to one side when it is revved up, no thanks to that on a bike, especially if the engine is going to be a stressed member of the chassis/suspension. Again. not an engineer but do I have it wrong somehow?
