G'day All, I have 08 Motovert Pro 125 with Marzocchi forks and the brakes had little feel and the firm squeeze required to slow the bike down quickly fatigued my forearm. They were slightly better when I replaced/bleed the fluid but they were still the worst brakes I have ever used on a bike. They are large single piston items and seem to be the standard issue on many of the Marzocchi forks. After a bit of research on here I went with the twin piston GPX brakes from DHZ and they are fantastic. The lever pull is softer with great feel and allows me to effectively modulate the braking power the way you should be able to. I wasn't 100% sure about the fitment when I ordered them but they bolted up no worries - 51mm centre to centre caliper mount. Best mod I have done so far.
