I just read the Roadracing Worlds article on the tire shootout, and have a few questions. Has anyone measured there stock tires and the new tires that they have put on to see if the geometry is the same? I just got Pirelli Diablo Corsa tires and will be putting them on my bike in place of the stock Dunlops. I've read that many riders have liked the tire on there XB but have you changed up the the geometry of your bike for the new tires? Thanks for the help. | ||

I left my fork position the same and my Metzeler M1's (the same carcass as the Diablo's) felt quite nice. I've then moved a ways from the stock setup. | ||

Dude, you're gonna love the Corsas. I'm on my second set now..Be careful on the first ride with them. My experience with them is that they turn in a lot better than the stockers and warm up better/alot quicker and wear more evenly. btw, they seem to have a noticeably higher geometry in the middle. Which would probably explain why they turn in better. I feel much more confident in all riding conditions with these Corsas too. | ||

I replaced my D207s with Michelin Pilot Power and it's clear that the Michelins have a different profile. The Dunlops were flatter with more sidewall - the Michelins are more rounded and have tiny sidewalls. The overall height and width is the same. The Michelins are the kind of tyres you can just forget about and enjoy the ride - hope your Diablos are as good ! | ||

I just replaced my 207's with 208's and I like them. | ||

Sounds like I'll just leave my settings alone on my bike with the new tires. Although I probably will change suspension settings for the track when I go there in June. | ||

i just picked up a pair of diablo stradas, they claim to get a few more miles out of them than the corsas. first question, does anyone have experience with these, and second i know since they might be a little harder and a tad less grip, any reason why i shouldn't be able to push em just as hard if not harder than my stock dunlops? btw i got about 5000 miles out of the stockers | ||

Dude, you're gonna love the Corsas. Be careful on the first ride with them. My experience with them is that they turn in a lot better than the stockers and warm up better/alot quicker and wear more evenly. I found this to be exactly the same in my experience too. In fact I'm staggered by how well these tyres have lasted mile after hard mile on my 916. That wear in thing is true. If you take these tyres to a right hand track you'll see the wear difference on one side is quite apparent. Ride some more on the road and you'll be amazed how quick they'll even out the profile. btw, they seem to have a noticeably higher geometry in the middle. Which would probably explain why they turn in better. This is certainly true. The profile is much higher and wore a hole in my Harris carbon hugger. Something several other tyre brands had not done. They are superb tyres and that coming from me is something you'd never hear me say about tyres. I'm one of those guys that will ride on any tyre and will argue one has to be bloody talented beyond street riding to tell an absolute difference worth a toss between a Michelin Pirelli Bridgestone or whatever. Hell they're all bloody good compared to 20 years ago! Give me a used take off and I'm content no matter who made it. CORSA'S however are different. They are simply bloody awesome and I who would refuse to be embroiled in the tyre bullshite (usually LOL) will actually put my good name and reputation on the line for them. What do you mean good name and reputation??? Watch it dudes! Good luck and let us know your findings and be careful of your hugger clearance!! Rocket | ||

If you're willing to put your "questionable" good name & reputation on the line (hehe) then they must be good.  | ||

The Metzeler Sportec's are the same carcass as the Diablo's. Pirelli and Metzeler are the same company. The Metz's ROCK too  . | ||

I beg to differ. I've ran several Metzeler's over the years and frankly they're just as good as anything else. That is EXCEPT Corsa's. I believe I'm correct in saying it's all about compound and that's where the Corsa is not the same as the Sportec. Rocket | ||

I ran some numbers comparing published diameters of M1 Sportecs vs published diameters of Dunlop 207 OEM and what I came up with (again relying on published manufacturers data) was that going from stock 207's to M1's cause the bike to be higher in the rear by 7mm. Although Pirelli doesn't publish the diameter, I have read that the construction is basically the same, so I would guess the the same profile difference would apply. However, I found that the Diablo Corsas were much more stable but required just a little more effort to turn, so either it's less than 7mm, or just a better tire. With that in mind I would leave the geometry alone as you are going to like the quick turning better. I would suggest a steering damper for the track though (and I love mine on the street as well). | ||

As if by coincidence MCN UK published a recent tyre test just yesterday. Without going into detail right now Pirelli came out top in every category but one. Interestingly the one group they lost out in marginally was the Sports Tyre which is said to be the group where most road riders on a sports bike can ride committed on this rubber which is good for grip and longevity. Metzeler Sportec M1 scored 92% beating the Pirelli Diablo into 2nd place with 91%. A little perspective - 3rd place Michelin Pilot Power 88%. The Performance Tyre category shows a different story though. Said to be more of a tyre than you'll ever need on the road and aimed at the committed sports rider and track day use the Pirelli Diablo Corsa scored a whopping 99% in 1st place. 2nd place Pirelli Supercorsa Pro Street with96% and 3rd with 93% the Metzeler Rennsport Street Compound. More perspective - 90% to 4th placed Dunlop Sportmax GP Racer. The Extreme Tyre category again went Pirelli's way. Aimed at racers and serious track day addicts in this category Pirelli Supercorsa Pro SC1 scored 99%. Michelin Power Race jumped in to 2nd place with 96% and 3rd went to Metzeler Racetec K1 with 95%. More perspective - Dunlop D209GP in 4th place with 90%. Hope this helps convince anyone how awesome a tyre Pirelli make. My opinion as I've said, if it wasn't Corsa's fitted on my 916 I wouldn't bother writing home as I'm not that smart to really believe anyone is clever enough to really exploit and tell the difference on the road between one good tyre to another - unless it's a Corsa of course Rocket |
