Are the brake lines OEM, or aftermarket?
There is very little room in the front of the modern 600RR, and routing can be difficult. When I switched to a dual line setup, I had to route mine forward, which can lead to the lines bumping into the from fairing stay like it sounds like you're describing. When I switched back to a single line, I was able to route it so the banjo faces towards the back of the bike, which was much better.
I am at work at the moment, but I think the line should be closer to the fork, inside of the clutch line. The clutch line should sit in the little U holder that branches off the right clipon, and should move back and forth inside the protective sheath; some rubbing on the sheath is normal, but the lines should be routed to cause the least amount of strain and contact. Some silicone spray in that area could be useful. A picture of the config right now can help with troubleshooting.
