Does anyone know what the annoying rattling/scraping noise coming from the front wheel area is on my k1100? It is especially noticable when I reverse the bike and turn the handlebars far left or far right.
Thanks, JAG

K 11`s got floating discs up front, check the play between disc(s) and disc hub(s).

Ditto, it's most likely your floating brake disk rotors making the noise.

Check your "bobbins", as they become more worn, the noise will get louder.
The bobbins are the disposable part of the floating disk system. Cheaper to replace them than the acutal disk or carrier.

You should have some "side-to-side"(as looking at from the front or rear) play, but very little "rotation"(as looking at it from the side) play.
If you have too much "rotation" play, it's time to replace the bobbins and e-clips.

Thanks Scott. Any idea what the new bobbins will set me back?

You can also buy Beringer ones, I installed them on 2 bikes and last longer than the stocks.

Thank you #6. I got mine from Motobins, but I see they don't stock them anymore. Good to know Beringer has them.

Hey Number 6,
Thanks for the links, one would think that all those concrete blocks fell on my head. I kept spelling it wrong and ended up giving up in aggravation. Thanks.
