Are these the same thing (See Part #13 in image below), or do you mean complete with chrome trim and badge (See Parts #16-20 in image below)?
The full part number for the Front Mudguard is T2305869 and in comes in many colours and 4 Black versions for R3 Roadsters from 2010 on exist. Phantom Black (has pearl glitter), Phantom Black with Tornado Red stripes, Matt Black with White stripes and Jet Black (a plain black used on early model R3s). The Two character Alpha code is the colour code.
By chance I stumbled upon part numberS for the white and red stripe decals for the front mudguard - I have never noticed this before:
27 DECAL, MUDGUARD, FRONT, WHITE Part Number: T2303244 and
27 DECAL, MUDGUARD, FRONT, TORNADO RED Part Number: T2303134
