Hi, I have completed 1200 km on my new KTM Duke 390 model and first service is done. I am facing a issue from the day one but the service guy says it's common in a high capacity single cylinder motorcycle. The problem is the bike jerks in low rpm, below 3000 - 3,500 rpm even in first gear. The feeling is like that the fuel is not coming to the engine but the problem disappears in high rpm. No problem in open road or highway. But it is irritating if I ride in traffic in slow speed. Is it the characteristic of Duke 390 or a problem with my bike ?
