But i forgot we've then gotta spend the next 5 months arguing about wether the tyres are any good, blah blah blah. Someone make the rules, lets build our bikes to them and go and race! And it could all be sorted by Christmas!

Andy the problem with the tyres is the availability, one company appears to have the monopoly on supply.

Lets go ZR and they are available from anywhere.

The problem with the ZR rated tyre is that Pirelli have specifically stated that the bikes are not heavy enought and dont have enough power to get them up to required operating temperatures and as such wont endorse them for the series.

That is not the case for the HR rated tyre.

This is important because it is the racers necks on the line with this and saftey is important.

Supply of the HR rated Rosso shouldn't be a problem next year, as I currently understand it.

Before anyone starts on it I am not aware of any good reason to move away from Pirelli tyres!

Although on the Pirelli.com website there is still no mention of H rated Rosso's
And I do find it strange tha Pirelli endorsed the use of Z rated tyres in 2005 and 2006 for the Desmo Due series if they now deem them unsuitable

We tried all sorts of things over the winter & trackdays of 2005/06.

We found the ZR tyres took longer to warm up which is probably a benefit in DD, especially Class A as I now find the HR tyres go-off quickly on the 620's. Kyle found them pretty good too, looking at some of his old lap times. We find the HR's very good at their first meeting and not-so-good at their second meeting and I'm sure Tim will confirm this too. I remember buying Skids old tyres and winning races on the Class B bike though.




I've got Dialbo corsa's on my 900ssie and its an ideal step-up, faster, better suspension and more grip.....

900ssie looks good with the DD bodywork too

As Tim has not yet posted, I can confirm with Andy that after one race let alone one full meeting the HR Diablo's on a 620 have lost there initial grip and start to slide noticably.
Apart from that they are a good reliable and consistant tyre.

That may not be a bad thing if that 'monopoly' enables said company to afford to be present at every round of the championship! I think the convenience of not having to worry about buying and bringing tyres (and maybe changing equipment) easily outweighs the small additional cost for the tyres.

I have always seen FWR as a cheap place for tyres and this is there current prices on H rated Diablos. http://www.fwr.co.uk/pirellit.htm#diablo
110/70H17 - £69.00
120/60H17 - £69.00
150/60H17 - £95.00
160/60H17 - £99.00

There is no 120/70H17 front listed so based on a 60 profile front a pair will cost £168 so not as cheap as Holbeach

a pair of ZR rtaed is £181
120/70 ZR17 - £82.00
160/60 ZR17 - £99.00

I think the deal we get along with the support in the paddock and several tyres as raffle prizes is a pretty decent deal

Just my tuppenth worth on the CDi boxes. As i understood them they had a modded curve in but not necessarily for more power. The ultimate advance needs to be kept in check to enable them to run on any fuel and Ducati know this.
I've certainly seen no advantage of note in using them. What they did/do give was/is a monetry saving in replacing the stock boxes should they fail. The DP items are cheaper, as a pair, than buying stock parts. This has a been a reason that i know of in two cases where they have been used.

There's more adjustment to be had on the pickups and you'd never police that, so for what it's worth, i think you'll be wasting time, effort and energy trying to police the DP igniter boxes.......
