Hello, new to the forum. Just purchased a lightly used 2019 Duke 390 with 1400 miles. I am not sure if it’s because it’s been sitting or if this is the reason it was so cheap. For 4k for a low mileage 2019 with a tuner, exhaust and intake mod, couldn’t pass it up. I am have issues with the front brake, it happens very seldom. In the 4-5 hours of riding it’s maybe happened 5 times. The brake feels pretty squishy and a hand full of times I have went to brake and the lever went all the way to the grip with nothing, let off and compressed again and it braked. I tried to bleed it, no air came out at all after bleeding it enough to have to fill the reservoir 3 times. Still has a squishy feel, and has done it 2 times since I bleed it. Not sure what else to do, I have done some research but can’t find anything about it, is this a known problem with these bike? Thanks for any help! So far I love the bike, which is surprising coming from super sports and super motos.
