I just picked my 390 up (I'm in the US) and I would concur that the front brake is the weak link on the bike. I've had several other bikes with much better 'bite'. I'll be upgrading my front brake system piece by piece and will report on what I find each step of the way. Mind you, my feedback will be purely subjective based on what I 'feel' on the bike. It seems the 320mm disc is not available at this time. My dealer said it is noted as discontinued through KTM. So, it may be tough to get a hold of one. I'll start with EBC pad upgrade, then try the wave rotor from KTM, then I'll install a new radial master cylinder with good fluid. I just ordered a 16mm radial unit from Braking. But it was a wild guess on the proper size required. If anyone has a definitive knowledge on the proper size, I'd love to hear from them. Thanks.
16mm should be plenty, make sure you get rid of the ABS and give the bike a proper bleed. THAT is the weakest link in the brakes...
