Most of you have already heard about this. As a reminder, the Diablo promotion is only good on Diablo rear tires bought through March 31st. But front tire supply may be limited. Here is a link to the coupon if you are interested: Diablo Free Front Tire Coupon Possible loophole? I noticed the coupon does not indicate the Year. I think you would have a good case if you bought a rear Diablo first Quarter next year and sent in the coupon again!! Mike. edited by xb9er on January 30, 2004 | ||

Sent my coupon in about 2 weeks ago. No front tire yet... | ||

Sent mine in just two days ago. Also waiting. A guy in my local sportbike club got his in less than a week. | ||

What's the story on the Diablo? Are they good tires? I am going to need new tires soon and I was planning on buying the Michelin Pilot Sports because of all the good things I have heard about them. How does the Diablo compate to the Michelins and the stock Dunlop D207s? | ||
| Xb9er |
I don't have any experience with Michelins. Diablo's are similar to Sportec M-1's (Pirelli owns Metzeler). My new Sportec M-1's and the Pirelli rear I got are both made in Germany. Anyhow, this tire test report includes Pilot Sports and Diablo's plus other tires. Check it out: NESBA.com MCN Tire Guide edited by xb9er on January 30, 2004 | ||

Everyone has raved about them in the sportbike community, BUT no one has run them in really hot weather I have seen. At TWS last year, a guy wadded up his F4 and from everything I could tell, the tire just "greased up" like most street tires on the track do. So, I think the tire looks to be everything they say it is, but it also appears it is subject to the same problems that all other "sport/trackday" tires have. That primarily is that when it is warm and you are running hard, the tire will move around on you. Marcus | ||

For track days wouldn't one use the Diablo Corsa as opposed to the Diablo "standard" tires? Mike | ||

Marcus, A question: if you were on a street Buell (M2, S2, XB12, ?) on a long ride in the summer heading across South f'n Dakota towards Deadwood for a south run down the Black Hills at speed to Custer, daytime temps hovering between 90°F and 100°F with freeway speeds running between 75-95mph, stopping only for gas and walking refreshments (Defn: walking refreshments: those that you buy while paying for the gas after taking a leak and drink completely as you walk back to your bike at the pump), hot tires, fairly hot day, long freeway runs, heading into a hot curvy mountainous canyon road, what tires would you run? Would the Diablos work or grease out. Just curious. Thanks for any reply or insight. Mike | ||

Hey Mike, Most any tire will be fine under those conditions. I may be assuming too much here, but I see a lot of Buells at the track days and I figure you all on this board probably run a track day or two a year. Marcus | ||
| Mikej |
Yep, a bunch of us do. I haven't yet but may run one late this summer sometime. Need new skins on the S2 and am starting to shop around a little. Thanks for the insight. I'll probably be tearing apart the S2 forks this spring once the garage unfreezes. Been gleaning tips on that from your's and others comments as well. Thanks again. | ||

Marcus, I checked your profile and see that you are a racer. I live in Georgia where it gets in the 90's almost every day during the summer. It is not abnormal for me to put 200 to 300 miles on the bike in the twisties at a decent pace in one day. So, are you saying that the Diablos would be fine under those circumstances or would I worry about losing traction? Thanks for the help. I am certainly not very knowledgeable when it comes to tire selection. | ||

Yeah, It is really important to know that there is nothing derogatory meant in the statement about the Diablos. Tires are made in different compounds. The tires on the normal street/sport bike (Say like a Dunlop 207ZR) are made to work at predescribed operating temperatures. On a normal day (90 degrees) with your tires at proper inflation rates, you tires will not get over 120-130 degrees F riding on the street. On the racetrack, they may get to 160-200 degrees F. Tires are a petroleum based product (although manufactures are starting to go to pure synthetic rubber), they are designed to work at temperatures that prevent excessive release of "oil" from the rubber. If the rider exceeds the heat range from that tire then it gets "greasy". Since no one manufacturer can get a tire to work in all conditions, there will always be street tires and track tires. Tires that are "Sport/Track" are usually a compound that works across two or three ranges well. Specifically, when you leave your driveway at 7:00 in the morning to go to work/play or whatever, you tire may be at 60 degrees F. You may ride it harder that day and get them to 125 degrees F. The new generation of sport/track tires can handle that. Pirelli in the case of the Diablo seems to be able to handle this situation better than Dunlop (207ZR) and Michelin (Pilot Sport). So "greasy" is something all tires undergo, Most street situations will not even come close to this condition regardless of tire/street temp. On the track, it is another story. Unless you buy a true DOT race tire, just be mindful that your street intended DOT tire is not going to do it without some compromise. Marcus | ||

Marcus, thanks for the thorough reply. | ||

Mike, Mac, It is the ultra hard and repeated braking and acceleration that puts the serious heat into a tire on the track. You just don't get that kind of abuse on the street. | ||

I think my Diablos are great on the road, but when I do my track day(s) this coming season you can bet that I will be running fresh Dragon Corsas, or Super Corsas. |
