Hey people, the ZRX has an annoying vibrating / rattle sound coming up from front of bike somewhere at around 3.5 - 4k in the rev range. I have checked everything i possibly can. Anybody had this problem or heard of anyone with this problem.

Its driving me nuts and i have to fix it..


Thanks, Paul.

is it coming from the bikini fairing. put a strip of tape where the inner piece joins to the fairing at each side.
see if this fixes the problem

I had that recently on the 9, turned out the mob that did my fork seals forogt to tighten the bolts on the lower triple clamp... not happy Jan!

Had a very similar rattle on my rex just last weekend, but only occured for a very limited rpm range ie 4000 +/- 50 rpm. Turned out to be the speedo cable retaining nut on the back of the cluster. Only figured that one out when the speedo dropped out on the way home from our ride on the weekend

can also get an annoying buzz from the dash if the rear cover of the instrument cluster is slightly lose

will check out these possibilties...


Keep em coming guys, much appreciated..

Mate, start at the bottom of the fork legs and work your way up. I had a buzz at 2900-3200 like TC above and it was the fairing inner rubbing the inside of the fairing. A clean and reassemly with a tiny bit of black silastic fixed it. Ooh, Ooh, also, at higher revs, the radiator shroud-mounts can buzz and it sound like its coming from the front. I took the four small washer-spacers out (the ones that line the rubber grommets) and shortened them by about 0.5 mill or so and screwed them back in with a little vaseline to help the neoprene out: buzz gone!

Ok have checked from top to bottom. I think it maybe the speedo head ?? It seemed to have almost gone until i touched the knob that you use to reset the trip metre.. Maybe its lose in there or something, any ideas ??

Mine does the exact same thing and I've never been able to find what causes it.

Hope that helps

It could be the keys in your pocket ??

You big prick! You only come in here to get your problems fixed! You never contribute anymore! So obviously we are just a resource for you now! Plus...you don't return phone calls! You're obviously too busy with ya netnanny buddies to worry about us lot now! So why don't ya go and get a big black one up ya!

Huh ?? Thanks for the big prick complement and doesn't everyone come here to get their kawasaki problems fixed you do realise it is a bike forum don't you and I have offered plenty of advice and I don't have any netnanny buddies and what phone call was I supposed to have answered and getting a big black one up me is a bit racist isn't it ?? Lucky for you I've got a sense of humor or I could have taken you seriously and written something courageous and scary and threatening.

Oh yeah blue 14,try the screen on the bikini fairing, mine used to vibrate at about 4000 revs so I locktited the screws and it has never come loose again. Don't use a permanent locktight.

My rattle is around the radiator.
When I reach down & hold it it stops.
My new can has arrived so I will be having a working bee in the shed during the week.
Fix rattle, fit can & chop rear guard....
