i was riding about 95km/h in 5th gear when i heard a strange high pitched sound coming from the front of the bike. the sound was intermitant, going for about 10sec at a time. -it stopped- then slowing down entering the next low speed zone the sound came back in a rubbing kind of noise. that my camera picked up. it all come from the front, where the engine and wheel are. the sound was louder than the normal engine noise, because i heard it clearly in my fullface helmet even with the wind noise.

my camera is only worth 20$ so... it coundnt register the sound in question for most of the time, but slowing down it heard it for a short period. very distinctively.

whirling rubbing noise?

Salut Kenji,

Est-tu de Montreal ou region?
I'm having trouble really hearing the exact noise.
It could be a something on your front wheel (clearance, rattle, etc) since it's happening only on deceleration.
Also check your chain for the correct tension and alignment.
Without a better sound clip or being there it's kind of hard to troubleshoot.
If you're on the Rive-Sud drop me a line and I'll try and meet you to see if I can help.
Or I can give the name of a good mechanic.
