Hi Stefanos ,
On my race bike , when i used a steering damper it made it more difficult for me to feel what the rear end was doing . If i was coming out of a corner too hard i did not have enough time to feel the rear sliding and was not able to react quickly enough .
With out the steering damper i have a much beter feel for what is going on at the rear . I hardley ever have tank slappers , if there is one i roll on and ride it out , my steering stops are very close so that helps too .
I had a rs damper and can get the measurements when i dig it out of the garage .
