Question by : dose anybody know if a aprilia rs125 front brake caliper would fit on a rs50?
simply wanted to know for sure if a rs125 front caliper would fit my rs50, maybe someone has done a project or just uprated there bike like i want to and can tell me, another point, dose anyone have any experience with dot 5.1 brake fluid, is it really worth it? dose it make a difference? or is it just something they use in motor sport as abit of a gimmick?
cheers

5.1 is not compatible with any other brake fluid, you will find DOT4 is recommended on the cover of the reservoir – stick with that.

Discs are smaller on the RS50 so it probably would not fit, you might be able to swap the forks though.
