Hey Steve,

No offense taken; it's obviously about preference.  But, I WAS asked.

It seems like Ducati has quit using the SSSA on many of their bikes.  
Still, the SSSA is heavier and makes no sense to an engineer (see 
another reply). 

For the practical street bike, the DSSA doesn't have to deal with the 
moments, so the wheel and swing arm bearings are more lightly loaded and 
less likely to wear prematurely, or suffer a recall.  ;-)
