Mine does it. I haven't figured out where it is coming from. Nothing feels loose.

Might check to make sure that it's not the floating rotor... kick your front rotor w/ the toe of your boot. Is that the noise? Just food for though.

+1...That's me for sure. Heading into the dealer in about 15 minutes to get the steering head properly tightened up!

More than likely the head bearings need to be retorqued. They often need tightening after they have worn in a bit.

X2 on what spectrum said.

mine was more like a clunking sound

the service manual has the procedure to tell you how to properly do it.

there is also a thread floating around here on how to do it

alright guys i tried all of the procedures given by you guys and i still can hear the clicks. I was told by a couple riders at school about head bearings just like 'spectrum' mentioned it. Ima look into buying the service manual so i can do it myself. Thanx guys i appreciate the input by all. Ill keep u updated on the corrections.

Alright guys...listen to it. First, the steering head bearings in an 1125r...as well as XBs...are sealed type roller ball bearings. This means no steering head bearing adjustments. To do a proper check on such on these bearings you secure the rear wheel very well, jack up the front of the bike, and use a spring scale to measure the resistance of the bearings. Resistance for the 1125r is 1-7lbs. IF they are bad, then you replace the bearings. No adjustments.

I went down to my bike and tried doing a 'by ear' type test (holding the front break and pushing the front suspension up and down). I noticed a small clicking sound that I never really noticed out of place before. While my brother pumped the bike, I listened to determine its location. It seemed to be inside the fork tube. I believe this is an ok sound, if yours is making the same sound as mine.

I have noticed floating disc make noises before, but these seemed to be more common on v-rod type models, and still seemed like it wasn't a concern.

As far as your concern goes, I can not 100% diagnose the problem with what was said but I will say there is no steering head bearing adjustment. If you feel a big enough concern then you can take it to a dealership as you should still be under factory warranty. If there is a concern then it will be taken care of virtually free, if not then you can go on your merry way.

Here's the procedure to re-torque (adjust) the head bearings. The pull test is just to verify that the bearings are not wornout. The re-torque procedure is the head bearings adjustment procedure.

Put it on a stand or jack it up. The Bottom line is the front-end can not be touching the ground or bearing any weight. By that I mean you cannot use a front stand that lifts by the triple tree. I use a scissor jack under the jack points.

1. Remove the steering stem pinch fastner at the upper triple tree.
2. Loosen the steering stem capnut and back off several turns.
3 Remove the pairs of triple clamp pinch bolts (lower fork pinch bolts on each side).
4. Tighten the capnut to 51.5-56.9 Nm (38-42 ft lbs)
5. Turn the front wheel all the way to the right.
6. Hook a spring scale into the front axle.
7. Pull the front wheel to center position using the spring scale and note the resistance measured on the scale. (1-7 lbs is ok) More than that and the bearings need to be replaced.
8. Install steering head pinch fastner and tighten to 27-30 Nm (20-21 ft lbs).
9. Install and tighten the lower triple clamp pinch fastners to 27-30 Nm (20-21 ft lbs).

If you don't have a suitable scale, you can just skip the resistance test, but make sure it turns freely side to side before taking it off the jack.

Most Important:
Be very very careful tightening the pinch fastners. On the XB's I've heard of several folks breaking their triple tree doing this.

+1 Spectrum on the pinch fastners...careful

I stepped down to 18 ft lbs...they were not "feeling" right going any further.

My forks make this noise but only when cold. Sounds like valves clicking to me. They (the forks) make this noise at different times albiet very very small time difference. My steering bearings are in good shape and at the proper tension. I'm so far not concerned with mine. It's done it since new.

That's kinda what I was thinking. Mine clicks when "cold", but I've been watching this thread to see what others experienced.
