I have been using my 1125r as my track bike for the last 3 years, have waited to put the 1190 on the track, but I am wanting to get her out there and see what she can do! I use a 190 series Dunlop N-Tec slick rear tire on the 1125, I am considering using a 200 series for the 1190 because of the bigger foot print, I spin up the 1125 on occasion with the 190, thinking a 200 would work a little better on the 1190. Curious what you guys are running and if you have any preference.
