    Hi everyone. I’ve not had my 2019 cbr1000rr for too long but I’ve noticed a strange noise when accelerating in a higher gear at lower speeds, say accelerating from 35 mph in 4/5th gear at around 3000 rpm.
    Has anyone else had this noise or any advice on what it could be would be great.
    I’ve added a video to show the noise

    thanks in advance

    Hi, my first initial thought on this is that 5th gear is too high a gear to be accelerating from 30mph.

    Most bikes, even cars will make that rattling, labouring noise if you accelerate in that high a gear, from that slow speed. Its the bikes way of telling you to drop down a gear or two! ;)

    If you're trundling around town 1st 2nd and 3rd is all you'll ever need, try that and see if it still does it!! Hope its not something more sinister though pal :eek:

    Sound like a bearing in the gearbox or possibly broken gar tooth!
    I'd drop the oil and see if there are any bits in the oil or in bottom of sump, first port of call.
    Although, it could be tensional vibrations causing the noise from low RPM and high load from opening the throttle like PauloHRC was explaining above.

    Sounds like an old car pinking with advanced timing :D mate drop it down a peg or two and get the revs up , posable to spin the crank shells doing high load at low revs . Hopefully nothing serious ;)
