I put a set of RJL-XX pads on my Ninja 1000, and was impressed.
So impressed, I ordered a set of XX pads for my Concours, and regular RJLs for the 400s.
The brake pads on the C-14 only have about 1000 miles on them, and neither 400 needed pads.
The set for the Concours was the most expensive set of brake pads I have ever bought for a motorcycle.
I hope they make as much difference on it as they did with the three Ninjas.
