Crikey, this thing has bad speed wobbles
Hi, Took my ZX10R to Philip Island race track in Victoria Australia yesterday for a track day.
I ran a pair of bridgestone slicks. I suspect the front slick is the cause of the trouble.
I couldn't even slowly feed on throttle past 220kph without a large wobble starting up.
Anyone come across this and tried a damper?
If so did the damper fix it?

I don't know about the wobble with slicks, but I do know that it gets twitchy with the stock tires at about 160mph. Damper cures it 100%. As a matter of fact, I would recommend it to anyone with a 10, because at some point you will experience the wobble and with the power that this bike has, it might just be enough to buck you off.

Have you fitted one? Which is the best to get?
Cheers.

Sounds like it is a tyre problem but from all other posts a damper is a must for track use.
Scotts, WP or Ohlins but go for quality.
What suspension settings were you running? Were there any other 10's there?

All I can say is that I retract my previous statement that the bike did not need a steering damper...
the front end isnt twitchy, but it certainly is light and with all of the power I have found that it gets a little TOO light sometimes powering out of corners..

I had a demo ZX10R last weekend that had PILOT RACE front & rear and it also had a VERY CONCERNING speed weave above about 200kph. It's severity was dictated by the amount of power i wound on. It was bloody scarey though. I think that this bike maybe very sensitive to tyre profile.
Didn't stop me buying one though !!

I definately agree.
I can tell you though it is extremely fast. My friend has a new GSXR1000K4 which has been de-restricted, BMC cleaner, slip on and remapped to suit. It is noticably slower in the straight but due to the wobbles faster around the circuit. (and the straight top end)
We swapped over and he was also slower on my ZX10R.
The suspension is standard with an extra click on the front comp, 2 on the rebound. The rear is also std with a quarter turn of rebound and half a turn of comp.
I'm going to put the street tyres back on and try some high speed passes to see if the issue is remains. I don't think it will. I got it up to 250kph on the street on some bumps and I don't recall wobbles..

The demo bike i rode had pilot race tyres on, all i noticed was excessive vibration, but there again i did not reach the velocity's that you did!!!!

A damper is a must - this thing gets light at the top of second and third at WOT.
Dunno if it's worse for heavier guys like me or not but I'll be gettin one.

I fitted a Scotts to my 10R, havent taken it to the track, but I did have a run against a 12R last Sunday and a did experience the light front end. But, she was never nervous, smooth and strait, no twitch, wobble or anything. I have Scotts on my 12R too and that is why I made the purchase again for the 10R, really easy to adjust while riding, it seems it would have a good chance of survival in a get off too.

Hi jonnyboy; question: I ordered mine yesterday should have next week
did you need to be picky in what adjustments on damper settings you choose? has high and low speed valve right.
since you have some experience; has it mattered much what setting for street namely straight line stability WOT thru gears. Have you played to see behaviour changes. I know I will find out just be nice to see what to expect ahead of time.
Who had better acceleration? ZX-10R or ZX-12R? hehe
Thanks.

The wobble explained by the first poster is most likely a tire problem. I have experienced it myself at the track on rare occasions. Change the tire and see if it clears up.
The damper issue one which seems to be unanimous. The 10R needs one. Now, which damper? The Scotts dampers have a dead on flat spot that allows some wiggle room at center and are shyed away from by roadracers. Cross mounts are better, and certainly more eye pleasing than side mounts, but from all of my research and personal experience, side mount dampers are in the most effecient placement to keep the forks in check.
As such, I am in the process of fitting a side mount Ohlins for an upcoming track day this weekend. I'll let you know how it turns out.

The Scotts damper does have hi and low speed valving and I never needed to adjust it must once she was set to where I was comfortable being able to maneuver the bike are in my neighborhood at low speed without having to put my foot down when turning. You can set the low speed damping too low and that my friend will cause a crash. So, when I had it comfortable I didn't need to change a thing. You feeling for setup may vary from mine. Hi speed strait stuff of hi speed turns, I don't change a thing. I think you'll really like the Scotts damper, I really like that you have the option to change the damping value and have a readable reference you can queue while riding. Just by glancing downward momentarily.
As for the 10R vs. 12R thing goes, I own both. The 12R still scares me when I get in it sometimes as the bike has more mass and takes more effort to get it to do directional changes and adjusting your speed for turns. For sheer acceleration though, I proved last Sunday that the 10R cannot be matched for acceleration by a piped 12R. I have a Micron slip-on on my 10R, I have not mounted my PC3usb yet, I don't have a map and I don't want to go through the same thing I did with the 12R dicking around a laptop forever trying to get it close. The acceleration of the 10R is so hard to put into to words. It would be analogous to trying to describe your first orgasm that someone else caused you to have. No real detail, it was just good and you want to do it again and again. Same stuff that killed the Energizer Bunny when they put his battery in backward. Just kidding about the Bunny thing.

I have had both the original D218's and Pirelli Supercorsa's on the 10 at a track day. With the additional grip of the Pirelli's, the bike got more "nervous". On the street, where the tires will never get that sticky, the 10 has been very solid feeling.
With my R1, I never had a head shake problem with a variety of DOT race tires at the track. When I tried Bridgestone 001R DOT tires, I developed a serious head shake. I think the shape of the Bridgestones makes bikes easier to turn. In some cases, where the bike might be marginal, that might not be a good thing.
