Since I need new brake discs for my mopped, I did some research. In terms of prices, I already hit something. 450 EUR for 2 brand brake discs for a small all-world 600. For a Porsche 911, a set of Bosch brake discs costs 100 EUR less. The Porsche has the triple power and six times the weight. For a C-Class, there are Bosch discs for just 25 EUR the piece. Are there purely economic reasons for these high prices or can the technis If so, what are the reasons?
