Radial RCS19 improves things
THE BREMBO RCS made a decent improvement to the braking performance of the R1, both in the crash braking tests and during fast laps of Brunters. It’s a marked improvement and there is a good case for fitting one to your bike. However, it won’t change your life.
My R1’s improvement was impressive, but my ultimate braking performance was still held back by bottoming forks, small discs and a conservative pad material. In many cases you’d be better to address those first, or at the same time as a master cylinder swap. There is potential for big gains then. Even as it is, the brakes feel nicer, but you are aware that there is probably more to come.
The other thing to consider is fitment. On older sportsbikes, there isn’t always room for a radial master cylinder without changing the position of the bars. This is true of the R1 as the Brembo unit touches the front subframe when the bike is on full left lock.
I like the stock bars and the ‘stealth’ look of my bike, so I’m going to stick with the OE M/C, which is well matched to the calipers and performs decently. That means that I’ll have to look at discs and pads next.

Brembo RCS improves feel and stopping power, but there is more to come
