Knocking noise in front fork - SV650.org

26-06-06, 12:51 PM

Hi, maybe this is normal but.......
I have noticed that when I go over a bump in the road of pothole i get a loud knock from the front forks. It seems to be OK in normal roads or in small bumps.
This is probably par for the course but as I am new to this, just want to make sure there is nothing more sinister..
BTW, I have a Pointy K3 with 5200 miles on the clock.
Thanks

They all do that sir

Err, yes, even my GSXR RWU forks do that, but to a lesser extent.

Really

Interesting. I was riding over a gravely road at the weekend on a downward slope, and the front end was rattling away as normal, but on applying the brakes(lightly, i was on gravel dont forget), is almost stopped. So this is leading me to believe that its either, Calipers rattling, or the calipers/pads combo rattling as there wasnt enough braking to compress the forks. Its has been discussed a lot of times before with various opinions etc. Have a search.

Agree with what you are saying, i have not pinned if its the forks or the EBC pads & disk. I am weighting on the pads as they have movement in the caliper and the disks as they have a little rotational movement. I also think that the fork make a little noise due to the spring somtimes knocking the side wall. Not a major issue as the forks work fairly well but are beeing drained and re filled with oil as i know some leaked out when i installed them (someone did not do up the bottom bolt properly, not me).

My USD GSXR750 ones have a different knock

"Bikes make noise", as Randy O says.

You guys and gals are a real fountain of knowledge

Ok we have determined that they all rattle, but being an inquisitive type.... What causes the rattle??
Sorry

Well its either the large springs that are in a SV fork, knocking on the side of the forks, or as i have read on SVrider someone had the idea that it was something to do with the headstock bearings. No one is 100% sure on an answer.

Yep used to worry me as most noises on my bike do, but learnt to live with it...

Or it might be some part of the damper mechanism, that's a popular suspect. Or the calipers.
