Strange, I've tested the Yamaha MT07GT and MT09GT (both brand new demo bikes with about 300km on the clock), the Vstrom 650 (2000km demo bike) and the Versys650 (4000km demo bike) and found the Versys having the best brakes in both braking power and feel of the bunch. Even though "professional reviewers" say the yammies have the best brakes.
Maybe you were/are used to the bite of the Tripple's brakes, but the Versys' brakes will also put the bike on it's nose with only two fingers.
Or, there could be something else going on.
How long have you owned the bike?
Were the brakes serviced every two years? Changing fluid every 2 years is a must, bleeding all air is too. If there's still air in the system, the brakes will feel mushy and the pads might stay in permanent contact with the discs, which will cause both the pads and discs to overheat and glaze (had that on my XR, air was trapped in a passage in the caliper, keeping a little pressure on the pads). After that, they'll never brake like they should unless you sand them all down.
