Michelin Power One RACE Tires

[Britracer]

Hi,

I am going to run the Michelins this year. Partly because they have the best contingencys at my club, the guy that sells them is one of the best to deal with at the track, I liked them on my Daytona...

I have a couple of questions for anyone that uses these for full on racing:

1/ What compounds are you using?...A front, B rear?...

2/ Does changing the tires on this bike affect the traction control?...does it have to "learn" a new tire or will it just plug away like normal watching the wheel speeds?...

For the traction control, the bike will 'learn' the new [overall] diameter of the new tire when it goes through its calibration. However, what it won't be learning is the new diameter of the sides of the tire when you start to lean it into the turns. This is where the traction control can begin to be impacted and where some tires have caused issues for racers with the stock traction control. I don't know if the Power One Race tires have been an issue or not though - sorry.

How does the traction control cope with the OEM tyres then? Doesnt the bike come with 1 of 3 types of tyre?

Yes on the tire options from the factory. I believe the three tires they've chosen are not too extreme in their differences in profiles. In other words, when the DTC calibrates the diameter of the tire being used, the profile differences are similar enough that the impact to DTC is minimal to nothing. Remember though... all three tires are street tires. Once you move to a race tire, the profile can change quite dramatically as they can be quite steeper on the sides to aid in turn-in and contact patch when leaned over.

Yes, this is what i was wondering. The V-front Michelin is pretty sharp and I'd really like some feedback from any users that have been on these tires.

It really depends on the temps you are running in. For colder temps I normally ran A front and A rear as I wasn't a big fan of the V it was different than the V front in the old Power Race series. The C compound rear wasn't available to me so for warmer temps I ran A frt and B rear.

thats good to know. I am in MN where we race when its 50 or 90's f so each weekend can be different. I wonder if I will only be able to get the new v front now?...will check with my tire guy. I noticed on my Daytona that front was alot more unstable at high straight speeds compared to the Pirelli SC. Had to use alot more steering damping which I wondered might counter the benefits of the v turning in easier...

Dunno what the rules are where you're racing, but here your tyres need to be rated to at least the manufacturers minimum speed rating, and the 'V' front is not a ZR rated tyre so can't be used in racing.
Hate you to win a race and get dq'd on a technicality!

Que?
Where did you read the V compound front is not Z rated?

Ummm, on the side of the tyre!
