Understanding that Ducati "had" to create the 999R models in a certain number as part of the WSB homologation rules, what exactly does that mean when it comes to comparing a bone stock 999R to a WSB version? If theres not much of a comparison, then why wouldnt the 999 or 999S do the same job in their eyes. Im clearly naive on this topic and would appreciate any knowledge you can throw my way.

well, beyond the R bikes you have the competition specials like the RS and F or factory series bikes. They share the same displacement dimensions as the R bikes, which is different than the standard 999 and S versions.

Yeah- there are a fair few differences between the R and the RS and F bikes. Maybe the materials/construction methods used in the connecting rod and the engine cases are what had to be homologated?

At the time of the FIM inspection for homologation, the motorcycles must be completely equipped with all road-using equipment. (e.g. full lighting equipment).
