I've been noticing a sound coming from my modern Sprint 125 originating from the front wheel 'somewhere'.
It seems to happen when I've ridden it, not so much when it's cold. (Ie this morning nothing, after 140kms back at home I could hear it.)
The sound can be reproduced when gently/slowly pushing the bike forward or backward, engine off. It's like the onset of a dynamo or cogs or something. It doesn't matter whether the disc brake is hot or cold... it doesn't really sound like a disc squeak either tbh. When you push the bike very slowly it's most noticeable, once rolling the sound is gone/lower frequency - though you can still notice something 'rolling'. I can hear it if I put my ear near the dashboard while on it.
The machine is only 1 year old - with about 6700kms on it, and has recently been dealer serviced and new front tires (120 now), though it's quite possible the sound was there all along but I've never paid attention to it.
Anyone has any ideas? Is this normal?
(I will check with the dealer as well when I get a chance to get there... )
