Definitely not a good thing. Just a word of caution for those that wander in here: never use the front brakes to slow down a wobble!! It'll dump you in the ditch very easily. I've seen 178mph (speedo healer installed) and the 1kRR is the 2nd most stable bike I've ridden at speed (busa is the absolute king -- may be a pig in the corners but at 200+ it's planted like a frikkin oak tree).

Good luck sortin' it out.

 

+1 on that. I say tires tend to be the #1 suspect. Check psi and if you have hitchhiker.

 

Yes. The tires and/or the shock together could be the culprit.

If the suspension is not set properly and/or the tires are worn/old/cycled, you could get this type of behavior.

And...the HESD is not foolproof. I fooled it. I no longer have an HESD. Went to a mechanical damper.

Dont get me wrong. The HESD works pretty good most of the time for most users. But I want it to work ALL the freakin time[:@]

 

You said u want the HESD to work all the time..So when is the time it doesn't work for you and how do you know it?? Juz curious dats all...

 

I dont know if anyone else has heard this, but if u plan to do a burnout, dont bother to balance your tires cuz its gonna spin on the rim and cause what is happening to you...so im bettin on rear tire.
Good luck and keep us posted

 

When your bars are flappin back&forth and your ankles are slappin hard parts (and your life starts flashing before your eyes, AND you start wondering if traffic behind you is going to turn you into ground beef...) these are good indications that your HESD does not work ALL THE TIME. []

Luckily, when I gathered up enough sense to let go of the bars, the only damage to occur was a sore ankle. [&:]

 

I stopped by a new bike shop the other day just to check it out....anyway the guy that worked there asked me if I have had any problems with my HESD. I said that I only have about 300 miles on it and no, no problems so far. Then he goes into story mode about how two friends of his have the 06 1000rr and the HESD malfunctioned and gave both of them balistic headshake at high speeds?? Keep in mind that this is coming from a shop I wouldn't go back to and he was a die hard ZX-10 freak. Is there truth to the story? Are the HESD malfunctioning causing headshake at will?

 

Well, I have had my CBR1000RR for over a month. Put over 2200 miles on it and has been well over 160.(stock speedo reading 182 but I know its wrong). I dont ride the long wheelies but I do pull it up all the time. The fastest I have had it up was at 110. I have not had any kind of shake what so ever.

 

Lets clarify this.

I dont think they are malfunctioning although the meaning of the word fits.

I think they are not designed properly with regards to electronics thus there is a window for error.

Take for instance the mechanical damper from Scotts. Scotts has high and low speed damping such as the HESD. There are no electronics involved with Scotts so unless there is an internal anomoly such as part failure (99.999% unlikely) or air in the system, it will work in every instance. If there was air in the system, it would be evident in every instance. You'd feel it and thus would get it corrected (like air in your brake lines).

The HESD has a window for error and thus will work one instance and has the possibility to not work another. And this could occur to a higher percentage due to mitigating circumstances such as suspension setup/tire wear/road condition. Whereas, a mechanical damper will always combat these circumstances.


*edit* I almost forgot. Ive seen one for sale on one of the forums and was told by an Aussie Superbike racer that his team uses the HRC part. If the production HESD works so well, why is there a HRC part for the "same-but-different" item? And before you ask, I believe it will only work with the HRC ECU (Cant confirm that one though).

 

Well i had it out last night and kicked up to 117 on the bridge before the back tire felt like it was gonna try to get ahead of the bike and sit sideways (ie it was wantin to kick out bad). Couldnt tell if it was the tires, the fact that the bridge might have been a lil wet or if it was the wind. Didnt feel windy, and on the way down the bridge i did 110 with no problems. It seems to only start shakin around 120 or 125. Gonna take it up to the gas station and measure the air pressure in the tires tonight cause i dont have my own gauge right now. Ill try to hit 120 later tonite after the cops arent around and there is less traffic. Just hope it doesnt rain and it aint windy. Kinda askin for alot when u live by the beach and its at the start of hurricane season though but we will see.
