I understand your predicament although bummer there are no tracks in Israel, would you not be able to visit the UAE with the bike and ride tracks there?

As for Racers and suspension settings, most will have ditched the stock suspension and will have no other advise for you other than the rear end of the bike is poor and to throw money into it with a replacement. You would be better looking at track day people who have had to deal with the same issues here even if they went to a track suspension specialist to help them dial it in. Of course, smaller countries including Finland do not have a wealth of specialists on standby at tracks to help out so like you we have to come here and research the info here and do trial and error.

My understanding of the Gen 4 ZX10R is that conventional sag settings are not effective. Now I used Sportbike Riders settings as a test baseline to start with and made a little adjustment for myself. Also, I am running a larger rear tyre (now a Bridgestone RS10 200/55) which will raise the rear end a little as well.

Do some searches on Sag for the Gen 4 and also shimming the rear shock which is a cost effective way to raise the rear end and get the standard suspension working a bit better. Some people also prefer adding links to the chain and running the rear wheel further out on the swingarm to give better stability but then there are others that prefer the stock chain length and the quicker change of direction. With the front end the consensus is the forks are good enough and to run them near flush in the tripple clamps.

unfortunately dialing in these bikes takes some trial and error based on what you want from them. No model is the same either and even the same model can be different depending on mods done and how it delivers power through the rev range etc.

Here is a good starting point
Suggested Sport Bike Motorcycle Suspension Settings | Sport Rider

Look under the zx10r and then see how you go, tweak based on how you feel the bike performs. Maybe run a little softer given your weight or if you download the Service Manual from here, check what it recommends for oil and the stock settings for suspension from Kawasaki and use them as a baseline.

This is also a good read on the Gen 4 for you with regards to suspension

Anyone have some suspension geometry advice

I was in a similar situation as you are now. I own a 08 GSXR 1000 for 7 years and have done a couple of track days and races in the past (2012). Last June, I converted to a track only bike and did about 12 track days with her. I had a high side and fortunately didn`t get hurt or seriously damaged the bike and although the tires were in the end of their lives, I think a good traction control might have saved my ass.

I started looking for a ZX-6R, but ended up making a good deal trading a Triumph Tiger Sport I had on a ZX-10R 2011.
Installed a Mechatronics Ohlins on the rear with 6mm washer and another 2mm on the shock adjuster (8mm total increase) and a pair Ohlins FGR 166 pressurized carts on the front. First time I rode the ZX I felt a night and day difference. It was like riding a 600 with lots of power and was able to do same personal best lap time I had on the Gixxer, which I took 6 months developing my skills and the bike itself, that had front and rear Racetech gold valves installed by a pro tuner.

Bottom line: on top of the dynamics improvement of the Gen4 over your current bike, you will have the extra safety counting on the good Kawasaki traction control systemů go fot it!

I run at the track. Replaced front and rear springs. Put Ohlins 30 cartridges in the front and Elka shock in the back. Huge different from stock. Have no clue to help stock set up as I got rid of it as soon as I could. Fast and stable in A and B group and I'm 71 years old.

Wow ! I have more respect for you than to any rider I have ever known. Riding a sport bike at 71 years of age is amazing.
I know a good suspension can make all the different, I hope I'll manage to do it someday soon...
Keep riding man, I think you'll inspire everyone who reads your post.

Anyway, thanks for all the help guys !
I actually managed to fix the problem buy servicing the front suspensions.
After it was done I managed to cut 3 second (!!) from my previous best lap time.
A month later I installed a rear Ohlins and 0.2 seconds were cut off again (and than a pretty fast low side).
Bottom line, the bike works OK now.
I had to fly 3 times to Europe in a 3 months period just to get it done but it is done.
I still have to put the correct spring on the Ohlins. I bought it from a friend with a 120 spring, my weight is 75kg so I think 90 or 105 spring will work better. not sure yet.
Thanks !

Regarding Ohlins rear spring, I am 81kg and ride a 115 spring on my rear mechatronics Ohlins. With stock linkage, don't think you should go less than 110.

What is your race sag? What is your free sag? That will tell you if you have the correct spring. Sounds stiff to me. I'm 170 lbs and I am running a 100 spring with 30mm rear sag and 12 mm free sag. The shock and spring feel great. A group pace.
