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.

steering damper, you should get one or you can rebalance your tire

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

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.

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.

Steering damper just hides the problem... I would definately check out the rim, balance, and head bearings.

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

El Diablo,
What series Bridgestones?
The 636 had the 012/019 combo and those things were amazing, predictable slides, if it ever gave, which was VERY rare, maybe 5-6times in 3800 miles. These Dunlops aren't that bad, they have little feedback and move around a lot but havent let go totally on me. I've had 4 slides on this bike already, and this in under 850 miles, but we are talking 40+ hp machine :eek:)

Bridgestone Battlax BT56's... Excellent for sweepers and insane straightline speed, but not so great traction wise in the twisty stuff on the big girl.

you took the words out of my mouth gofaster....with a proper suspensioned bike the need for a damper is not need except those extreme circumstances....if you at speed and there is a nasty wobble start looking at the front end, rim, tire and balancing...
