A number of posts had commented on problems using the 190/60 until the suspension
was set up correctly. I have been running the 190/55 and have had no
problems with headshake at all. As I understand it the 190/60 is being
replaced with the 190/55 so before you go to the trouble trying to make
The 190/60 work on your bike you may want to double-check to see
If indeed the 190/55 is going to take its place.
My girl friend was using the 190/60 on her GSXR1000 and the last couple
Track days she was complaining about headshake above 105mph.
Well last month we where doing another track day and we had just unloaded
The bikes and she noticed that she had picked up a screw in her rear tire.
I had brought another rear tire for my bike since it was getting time to replace mine
Anyway, so I told her to put my spare rear tire on so she could ride and of course
Mine was a 190/55. After a few sessions on the new rear I asked her if her bike
Was having any headshake issues and she said no it magically it all went away.
The 190/60 209 can be made to work good on the bike but special attention needs to be
Given especially to the zx10r as it has a steep rake angle on the front And seems to be
sensitive to geometry changes. The 190/55 would be more of a plug and play size.
