Whining noise, maybe bearings?

  1. Hi,

    My bike, 2009 Kawasaki Ninja 250R, is starting to make a high whining sound that increases in relevance to speed, I think it's the wheel bearings?

    When it's idling, there is no noise, but as I increase in speed, the whining increases... and decreases as speed decreases.

    It's got about 1,800 on the clock, and it was serviced at 1,050, should an issue like this develop so quickly on a brand new bike?

    Should I be concerned?

    I'm planning on bringing it into the mechanics tomorrow night after work, hopefully they can check it out for me.

    Any advice/comments appreciated
  2. Check chain tension? (tight chain usually causes this noise, I've found)

    Chain cleaned/lubed regularly?
  3. Check your oil!

    Edit - Do you have a wife? and if so, could she be chasing you?
  4. Could be anything. Run the tools over the bike.
    Its amazing what works loose in the first 1000k
  5. Does it increase/decrease with speed or revs? Just checking. :)
  6. Speed. Revving doesn't seem to cause the effect, but I haven't revved it hard enough to tell.
  7. It's probably just tyre whine - nothing to worry about.

    Wheel bearings sound kinda 'crunchy' when they go.
  8. It's not wheel bearings.
  9. speedo drive ?.. have seen many older GPxs that have a whiney speede drive in the back of the dash ?. could have come a bit loose
  10. +1

    Check ya tyre to see if there is rounding off at the grooves...
    If the sound changes/disappears with change tyre pressure then you've probably found it

    Good luck
  11. Check to see if theres an old K series BMW hanging around somewhere :LOL:

    They weren't known as "a litre of whine" for nothing.. :p
  12. My washing machine whines when it's on "spin"
    Is your bike set on spin cycle?
  13. All is well as long as the whine is a good vintage.
  14. Well over on the K bike forums the '85 is regarded as the FYK (Finest year K) :wink:
  15. Found this over at the Kawai Forums:


    Basically: "Regrease around the speedo sensor next to the front wheel. I had this squeak so i greased that area and its gone now."

    Just got to figure out where that is and I'll probably give it a go in the morning.
