OK .... I have a MARCH 08 1125R that I got after trading my XB12R 2 months ago. The 1125R came with 3000miles on it and the standard Corsa III tires ......I decided I had to change the Corsa III... I had a terrible time with them.... In my favourute canyon road I could not get my knee down, which was something standard on my XB12R... The feedback from the bike was never right...When I decided to forget the bad feedback and push nevertheless , I lost the front big time ! !I almost crashed..... And it is not funny crashing on the road... As far as my past experience with the XB12R ... after trying different tires I found the Michelines to be the best ....giving it the best corner speed and good braking stability... So I installed Michelin Power One ... compound B in the front(31psi cold) and C on the rea (30psi cold).... BIG improvement ! ! ! I immidiatelly started to get better feedback and started to push harder ..... I also improved my setup, which was something that it was impossible to do with the Corsa III... Any how this is my setup now : I am about 100kg with riding gear and the setup is (so far)... Front ride height = 0 lines showing ( the bike came with 1 line showing)... that improved braking stability significantly Front preload = 7 1/4 turns in from minimum...I started at 7 and gave it an extra 1/4 turn....BIG improvement when leaned over Front compression = 1.75 turns out Front rebound = 2 turns out ,,,,I started at 1.75 and then tried 2 turns out...That gave Improvement when leaned over Rear Preload = 7 out of 9 Rear compression = 15 clicks out Rear rebound = 0.625 out... I tried also 0.5, but I did not like it ...the rear become too harsh and the bike did not want to close the line ... Anyhow , this is how my tires looked after the ride ....My confidence returned , after the terrible time I had on the Corsa III ... And I had a smile on my face  (Message edited by vagelis46 on May 10, 2015) | ||

The Power One is a track tire not really intended for road usage. They are intended to be used in conjunction with tire warmers to achieve the proper operating temperature. It is doubtful that the tires can reach proper temperature riding on the street. The tires may actually have less traction than good road tires. The rubber will harden fast since the race tire is designed for a limited quantity of thermal cycles. That being said, typically the cold tire pressure for track use is 30 psi on the front and 22 psi for the rear. Be careful with the tires on the road. | ||

And by looking at the wear on the tread, it looks as though your setup could still use some tweaking, some odd wear. | ||

What's "proper operating temperature"? On a 70-something Spring day, even the tires on my '14 Vmax got pretty warm during my 7-mile commute home (which involves a handful of corners and some decent lean angle). Not too hot to touch, but definitely near the upper end of what I felt comfortable with. How much hotter are track tires supposed to get? The Corsa IIIs do not work well with the 1125s. I switched to Pilot Power 2CTs (back in 2010--now on Dunlop Q3s) and that made a huge improvement with no other changes. | ||

Race tires are designed to be preheated to 176 deg F for approximately 30 to 45 minuets before racing to assure the tire and wheel is heat soaked. The ideal temperature temperature for the front is 176 (230 max) deg F and 212 (284 max) deg F for the rear. On the track you are either braking very hard or turning mostly at high lean angles continuously for the duration of the race. Street riding will not likely get them to temperature. Not running the tires at the right temperature can result in a slide if pushed when cold. The measurement should be taken after a minimum of two laps in race conditions on the side of the tread used most during the lap. Thus, if the track consists mostly right turns, the temperature measurement should be performed on the right shoulder of the tire and compared to the range recommended above to ensure that the tire is within this optimal temperature range. A Power Supersport Evo is designed for Street and some track riding and does not require pre-heat nor the high operating temperature required for track tires. | ||

I will testify to not running race tires on the street.I was messing with my brakes and went for a quick test ride on cold race tires.Barely grabbed the front and washed out at about 25 MPH with no gear.Rooky mistake but it still was a little painful and involved some road rash.Give cold race tires utmost respect! | ||

I have to vouch for the Q3 on the street. At least for me, they handle the corners and twisties well. And, you get a good amount of life out of them. |
