New V-strom has a "clunk" in the front end

I've had my 2009 V-strom for about a month now and the bike makes a "clunk sound when I hit sharp bumps in the road, is this normal. Its kind of a clunk/thud type of a sound. Could the steering head bearings be loose at this point?

This has been covered multiple times on this forum. Try a search and you will find lots of reading on the subject. The upshot of it all is that it is a normal sound.

Probably not your issue, but one thing that produces a similar sound is if the brake rotor buttons are 'shedding' the wave washers on the backside of the disk. The disc then becomes a 'full-floater' instead of a semi-floater and clunks on most sharp bumps. I've heard of it on several gixxers and seen it on my personal DL1k.

I don't seem to have the clunk in the front end...but I do have the front preload at about the middle ring.
Perhaps with no preload, the spring "bounces" off the endcap/spacer inside the fork and makes the clunck...just a guess.

I have noticed this on my bike as well. All of my other bikes have had solid rotors. By jiggling the rotor around by hand you can get it to make a slight clunking sound.

Mine had the clunk when new, installed Sonic springs and it didn't help.

Changed fork oil a few weeks ago and the clunk completely went away. I have no idea why or what changed, it used slightly heavier oil and the same amount.

I can't say they all do it, but it is REAL common and not a problem, just a feature. No one has really found out why. Lots of theories, but no solid explanation. It actually started with the SV650s, which do it too.

I also have a "clunk" sound on my VTX1300R, have changed out the neck bearings, new fork springs and fluid (but this was for the front end "wobble", not the "clunk"). I think that the front end "clunk" it can be a commonality with many bikes.

Just for the record, my DL650 does not have the "clunk".



Kindest Regards,
