I have a question for anyone who has owned an R1200S and upgraded to the HP2S.

Have you bothered to look inside your intake muffler (air filter box) or remove one of the suction pipes yet to see if the air horns are any different between models?

I am curious to know if BMW changed the design between the R1200S and the HP2S. The air box P/Ns are different but that does not necessarily mean that the parts are.

I have not heard much about any HP2S riders adding boxer burners to their bikes so one would assume BMW increased the ID of the air horns.

If someone familiar with both bikes could post a comment regarding the comparison that would be great.

Thanks -
