Ra­dial RCS19 im­proves things

Performance Bikes (UK) - - The Garage -

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.
