it's very unlikely there ever was an RS at 46K. There haven't been since the 851 Race / Corsa's or F1 750 Montjuichs..
the RS is not a 'higher' version. It as something seperate alltogether.
it is not freely available to paying customers, only to accepted raceteams with elaborate race programs.
it's more of what the FXX is to the Enzo
the RS has always been and is the base for the superbike for private teams. with every RS comes a seperate support scheme from Corse . Thuis goes from almost nothing to almost full factory ( Alstare)
Full factory bikes are labelled F0 and het year. Haga's 2007 999 being F07 ...
Visually the RS carries 2 very obvious main items: WSBK spec Ohlins gear + brakes ( FGR gasforks + brembo monobloc = 25K) at the front) and full Magnetti Marelli race electronics and telemetry (35k) . It is not homologated for the road. it carries race radiators and so no fans for road use cooling
RS is made by Ducati Corse which is a different/seperate company. As are all products for the SSTK catalog.
Even Ducati considers Corse a sep company as putting on stuff from the corse catalog annuls warranty , just a it does from another company ( if it touches engine management)
very probably this is the intro of the semi activ suspension that comes over from the Multi to follow the HP4 from beemer...
