The comments about a shorter wheelbase got me wondering whether the Boxer platform
might become more modular. So a GS or RT might use a long swing arm, whereas an S might lose a few inches from this.
I suspect that the air-cooled bikes will retain a following. The last of the air-cooled 911 (993) models are holding their value, and a 2010 / 2011 GS or HP2 Sport might be similar.
Personally, I'd be open to a Wasserboxer
. Particularly if the threatened S model tips up.
