I fitted the HRC Brake reservior kit to my bike. The weight savings are great but does come with a flaw. It appears the HRC Tubing causes the brake fluid to go cloudy. It doesn't seem to affect performance but whether the cloudiness is moisture or chemical reaction to the tube, I just don't know.
There is a solution. Tygon 2375 tubing. Its clear and its coated so does not react with the brake fluid. I will be using this in preference with my Brembo Master cylinder upgrade and amend the rear setup.
