Been riding since the early 60s and only had the desire to take my hands off of the bars once in all that time. There is a 2 mile stretch of road between Cripple Creek and Victor that on one sunny summer day in 1972 had a Kawasaki H1 deposited wayyyyyyyyyyyy over the edge, but that's another story.

The procedures in the SM for setting the preload on the steering head bearings is very specific and more than a case of just taking all the slack out of the bearings.

The preload set there will induce enough drag that it can be felt when turning the bars right and left when up off the ground. Preload is good for and necessary with that type of bearing and the drag it produces appears to be a factor in front end stability on Buells. It probably explains their not having a steering damper.

The older bikes that had steering dampers usually had ball bearings and those bearings can't be adjusted tight enough to provide any steering drag without damaging them.

I have yet to see a bike shop that even knows what a tension wrench is these days. I would check you head bearing tension as per the manual. It is quite possible that a overly keen young apprentice got to it.

worn out stock front tire. even the 208 will do it. I haven't see the problem with any other tires (diablo, pilot).

same prob here- steering bearing torque was fine, new tires fixed it. 207's suck, go scorps!

hey all,
stumbled on this thread, thought I'd add my 2 cents $canadian, : ).... first off: rode bikes for a dozen years, a dozen years ago...a LOT has changed!!

Here's what I've experienced on my brand new '03 9r: yes, the front shakes at about 50-60 mph too (you notice it a bit with hands on bars, with hands off (i know, i know, don't let go!!) it is quite noticable.) The hands come off ONLY to "see" how bad it might be...bikes are not supposed to shake, right? if they do there's got to be something wrong, right??

I went through the steps: stock tires (about 4000 miles) were replaced (with new Dunlop DOT race tires). shake still there.

Suspension settings returned to factory recommendations for my physical size etc. shake still there. (settings subsequently altered...)

Steering head "stuff" tightened/torqued, resistance test done ...all by dealer. shake still there.

steering head bearings replaced. you guessed it, shake still there.

the only thing I haven't done again is to reset suspension back to factory settings since the head bearings were replaced....dunno..maybe that would fix it...must wait unitl the snow melts..

So, stored the bike feeling a little frustrated....

Then, to pass the time during our non riding season, I picked up a couple of sport riding technique books (Code's "a twist of the wrist" and the one by Nick Inestach...) One of these guys (forget which one) says that front shake on a bike is normal!!!??? It's the bikes' way of settling itself....just relax your grip, and let it do its job.

So, not sure what this does to the thread, but anxiously awaiting your comments!!!

Spuds:

If the original steering head bearings were too
tight and the new steering head bearings are too
tight, will cause what "i" call SNAKEING ...
My 97S3T factory manual explained how and what the preload is supposed to be(lot of important
information is left out on later manuals ???) ...
"ONE OF THE MOST DANGEROUS THINGS IN THE WORLD IS A HARLEY-DAVIDSON TECHNICIAN WORKING ON A BUELL !!!"

A DEATH GRIP(holding on too tight-STIFF-) will also cause the same effect ...

Hey guys- my 01 m2 (just turned 20k) seems to have a really bad shake problem too- but I notice my shake (more like a back and forth wobble) around 100mph and up, doesn't matter road conditions or type of pavement. I work at a tire shop for a living and feel confident saying that I do not think its my tire (obvious wear from hard long corners but nothing choppy-michelins- otherwise excellent shape-they look recently changed), I might go so far as to say maybe balance is an issue-sticky weights only on the right side of the wheel- just want to make sure there isnt a bigger underlying problem here thanx for any input! ~BM~

Other issues to check include...

tire pressure - low tire pressure can worsen a head shake -

properly preloaded steering-head bearings,

properly assembled/tightened axle and pinch bolts,

proper suspension preload setup.

Loose fitting or bulky clothing, especially your jacket can induced shake into the front end. I've experienced this first-hand.

Even a too rigid grip of the handlebars can exacerbate front end shake.

I would not offhandedly dismiss the possibility of an out of balance front tire either.
