Have a word with Mark at Holbeach tyres the official suppliers 07733324640.

The H rating requirement is a stipulation from Pirelli regarding the safety of the tyres.

Desmo Due bikes do not have enough power and are too light to get the Z rated tyres up to proper operating temperature on the track, they are in the right envelope to work the H rated tyres properly.

That was not the question!

When are the "H" rated Rossos going to be available?

At the moment the exact date is unavailable but we hope to have some information from Pirelli in the comming month or two.

surely the point is to have them ready now so we can be practising on them in the season build up, and not to be presented with a new integer in the equation that is your bike set up just prior to the first meeting? why are we using pirelli's? What do the riders and the series get from pirelli other than a sticker?

If you want to lose the will to live, do a search for all the other threads on "Tyres" and "DesmoDue" !!!

in short, and in no particular order, back in 2005 Pirelli under-wrote the Diablos (and presumably now the Rossos) as being suitable for racing our bikes on. No other manufacturer was prepared to do so at the time, although they may now, given that we will buy a couple of hundred tyres a year?

If you can get to lap record times on Diablos, then it might be worth trying Rossos to see if they offer any improvement, especially on a February trackday.

As I've always understood it, tyres COULD be bought from anywhere, it was just that Holbeach were able to offer a good price.

The point in my case being that I can get tyres supplied and fitted locally, at a time that suits me for not much more that a pair of tyres shipped from Holbeach that I then have to collect from a depot when I've missed the courier and then still have to pay someone to fit them...

And the sticker is handy for hiding gouges in the bellypan

Use the Z rated ones for trackdays and save the Hs for racing?

I ran Z rated ones by mistake for half a season on my DD bike one year and they seemed ok, but there were a number of hot meetings.....?
