Is confirmed by R2 TOP FIX, realised tone-on-tone in order to fully become e being part of the staircase,without being detected anymore.
No more gap between plastic and steel, substitued with a precise colour match with the R2 top body and metal thanks to a lightweight, resistant plastic as required by design.
note: from now on the R2 TOP FIX is present, indeed, but it’s not apparently seen!
