Seriously? a 6 is smoother than a twin? Never would have guessed that.

BMW uses an inline six for their automotive products, which is far, far smoother than a boxer motor. I would say that an inline six is far smoother than a boxer.

I'm shocked, I tell you, shocked. Is that why they use more cylinders on those engines? Maybe we should be after BMW to make a six cylinder GS?

Yes, there is rocking couple in the Boxer twin. That's a different component of engine balance from harmonics. For a given power, displacement and cylinder count, the boxer motor is going to have less vibration than an inline or V configuration. I know this: All of my GS's have been smoother than my 4 cylinder FJR at cruising velocity. I sold the FJR because: The only thing the FJR did better than the GS was go 150mph...

That's why I sold the F800GS, totally annoying buzzing vibrations at cruising speed. Boxer is much nicer in that regard.

My 09 GSA was buzzy. My HP2E without the counterbalancers is smoother. Go figure.

Really? My buddies F800 is one of the smoothest bikes I've ever been on. I love that thing. It's like the top 3 best motors I've ever felt on a bike. For the new GS I was praying they would dump a 1250 version of that F motor into the GS. That would have been the perfect bike in my opinion.

An F motor WTF? - this was one of the silliest illogical nomenclatures BMW came up with as they had already used it for the Rotax engined 650 Funduro and not the same power-plant!? I will never understand what happens in those BMW boardrooms. Why not have given it it's own identity? Anyway I digress and yes is a beautiful engine being reimagined into the Husky Nuda and hopefully a proper DS version.

I don't know.. maybe it's silly but I really like it. driving that F800 is really enjoyable to me. Tell you what I hated though was the old G650 engine..

My F800ST was the same. Hands would fall asleep in less than hour. I greatly prefer the boxer.

While I don't have the newest boxer aka Cam Head, I can say that the F800GS motor is smoother by a noticeable amount. especially when the boxer engine was under a load.

Or could it be to give similar weather protection as the GSA tank without actually having a GSA?

Agree but the high frequency buzz. Made my feet/hands fall asleep...
