Head shake

I know this is probably old news but, is anyone else having issues with head shake? is it my tire (stock) ?? If I go over 110-120 I end up having to let out of it.

Also, going less than 30 miles an hours if I let go of the handlebars it shakes as well....wierd. I have about 5000 miles on the stock tire. Could it be this or something else??

Could be several things....
Tire with wear has out of balance problem...
If you have the stock tires and over 2k miles you may have irregular wear...
Poop can the 218's and get Diablo's or Pilot Powers and your problem will go away..

if not you must have a warped wheel or something loose...

...hmmmmmm, that reminds me. I haven't tested the hands free slow down since I mounted the PP's. Wonder if it's cured.

As for the high speed head shake. Look into that. ..out of balance, bad tire, bent rim... could be any number of things. none good. Mine is dead stabile through the limiter in 6th.

and lastly the notorious steering head bearings may require some maintenance.

Get rid of that 218. You'll love yourself more for it.

The low-speed hands-off nuisance shake is due to the front tire. Replacing it with some other type/brand of tire will solve this problem.

Headshake at constant higher speed in a straight line on smooth pavement should not occur, and is an indication that something is wrong. My experience has been that improper wheel balance usually starts making itself felt around 110 - 130 km/h and gets progressively worse from there up. Out-of-round or unevenly worn tires will also cause this. Loose steering head bearings won't help. Has your bike had the front-wheel replacement recall done?

Headshake over bumpy pavement while accelerating can be improved about 90% by softening front preload. Get it so that front sag (with you aboard) is in the 35 mm range for street riding. This will probably require backing the front preload adjuster almost all the way out (more or less depending on your weight).

A steering damper is highly recommended, but it's not a substitute for having the suspension settings right, and it's not a substitute for fixing something else that's wrong with the bike.


Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!

I started havin' the same exact symptoms (head shake problems on accel and decel and sloppy/floppy turn-in at low speed) at around 850 miles. Tightening the head bearings cured it. Fwiw, I have a Scott's damper and with loose head bearings I still got some pretty nasty head shake as the bearings seated in and got loose. Glad I had the Scotts! I'm bettin' it's out of spec head bearing adjustment. I just adjusted mine and I honestly think it rides better now than it did new. I wonder if mine weren't a bit on the loose side off the showroom floor.

Check/tighten yer head bearings and I bet this problem goes away. I'd still replace the D218's as the others suggested though. I'm equally as unimpressed with them as I was the Bridgestones that came on my busa. I'll never understand why manufacturers would put a mileage tire on a fuggin' super/hyper sport bike.
