With a bigger boss in centre of wheel you will struggle to see it at all, especially the new Brooklands type.
I'm getting a 350mm Sabelt wheel in Alcantara. But it's not a matter of almost hiding the ugly colour, it's a matter of not having it at all. It's also a way of having it as I would prefer it. I will also try out more modern (rear) MC tyres for the front wheels. And, I'm a bit embarrassed to say, I'm considering buying CNC'ed fluid reservoirs instead of the standard plastic ones. I know, it's just under the "bonnet, but the cnc stuff isn't that expensive, and it would make them match the oil tank in looks.
