Jasper,that bike of yours looks absolutely fantastic,one of my all time faves.
After consulting my vast library of literature and sales brochures (eh,sparkin?!
),the SP5 only came with the silver/grey wheels your bike is wearing.Black was standard on the SP3 and 4.
Black wheels would look great,imo.Here's a pic of an American market SPO with black wheels,so you could see what it would look like.
