I recently replaced the rear brake pads on my 2015 V650. Only about 8k miles on them but the old pads lost their grip. Holy crap the new pads are far better than OEM ever were! When I get the time I'll be replacing the front pads too.
EBC HH sintered pads.
It is a super simple and quick job to replace the pads. While you're at it, lube up the caliper slider pins and flush/bleed the fluid.
