I have got a 2016 Cb400 bike. At exactly 78km/h I can hear a sound coming from the bike. Is that normal? Very difficult to show mechanic because I have to ride it for the sound to appear. It sound like something is opening or sort. It only occurs when riding above 80km/h for 10-15mins, then when you drop speed a sound can be heard at exactly 78km/h. Hope somebody here got an answer.

Hi, I have got a 2016 Cb400 bike. At exactly 78km/h I can hear a sound coming from the bike. Is that normal? Very difficult to show mechanic because I have to ride it for the sound to appear. It sound like something is opening or sort. As it only happens at 78km/h after the bike have been ridden for like 10mins. Hope somebody here got an answer.
