  1. Certainly the race tire will have more grip and be better for the track. Using a 400 mile worn street tire is not a good option for the track. I would use the Race Tire on the track and then go back to your street Q3 for the street.
  2. I'm with Hotfoot on this one. She is spot on. You have really answered the question yourself. You are going 15-20 off the pace and your lap times don't change with a higher performance tire. So stick with that tire and get more tire life. The tire is not what is holding you back. When you up your pace and start to slide the street tire, then step up to the higher performance tire. Or if you want more insurance step up to the performance tire now at the expense of more tires usage. Its ultimately your call. Don't overthink this.
  3. Dr. Loannis, You questions a bit to general and specific to a region and the supply in that region. Please email me directly and I will be happy to answer you question (after I get more specifics from you), and if I cannot I will get you in touch with your regional supplier. steve@dunlopracing.com Steve Brubaker
  4. The Q3 is not a tire I work with at the track with racers. thus my first hand knowledge with it is limited. BUT, I did just spend some time speaking with the test riders that did all the development with the Q3, both for street and track. So I have the best first-hand feedback I could get. Track day pressure for the Q3 is 30 PSI rear cold, and no less than 32 PSI front cold. if you have a 600, maybe go to 28 rear cold, however, going lower you will not get more grip, but may have instability in the rear, so its not the solution if you want a good clean ride, keep it at 30 or slightly
  5. In a perfect world, one where your bike is right on the track record setting pace and the setup is spot on, you would then make changes to accommodate a tire switch. But since you have a mid pack or track day pace and setup, you cannot be certain of the direction you need to go with changes. In your situation you can just put on the new tires and start making small setup changes from there. Its kind of like being lost in the woods, no map, no compass, and asking if you should turn left or right to exit the woods. You might get more lost or not. But if you had a GPS and map, you woul
  6. The D211GPA and the KR448-KR449 slicks are the same tire before they go in the mold. same construction and they come in mostly the same compounds. The slick having a little bit more grip and wear becaue it does not have tread. Other than that they are the same. The 120/70x17 D211GPA and the 125/80x17 KR448 slick are the same width and diameter. The 190/55x17 D211GPA and the 190/55x17 KR449 slick are the same width and diameter. The 190/60x17 D211GPA and the 200/55x17 KR449 slick are the same width and diameter. These can be interchanged without ride hieght changes.
  7. Brad and Anthem both make good points. Pepsi puts to much emphasis on the tire temp as the biggest reason for tire grip. There are many other factors in tire grip. the construction of the D211GPA is different from the Q2. Thus the GPA has better overall grip, while the Q2 gives a different feel that makes a street rider feel more comfortable. Those different feelings may lead to some riders swearing by one or the other tire. Yes, you would not get the GPA to it "Optimal" performance level and temperature on the street, but that does not mean it does not performance very well at lowe
  8. The tire has tread left so its no the cords showing. It look like you locked up the front tire on a grooved pavement. IF this is the case it should slowly wear away, unless its now out of balance, in which you should rebalance it. Or, you let it sit on a grating of some sort for a long time, leaving an imprint. If this is the case it should go back to shape when heated or ridden on and it flexes back. Hard to tell by just a picture.
  9. Jason, You need to not get wrapped up in the sizing issue. Dunlop calls thier race tire a 190. simple as that. Becasue other companies make a 180 does not make them right or wrong, its just the size they wanted to call it. Honestly you need to call me so I can help your out. Everyone in the AMA and all club racers across the USA using Dunlop use the 190 with no issues. Track records and championships speak for themself.
  10. I sell only the race product. So I cant speek directly about the Q3, since I dont sell them. I am certain it is an upgrade to the Q2. However if you are on the track, the D211GP-A is going to be the best choice. The D211GP-A is also a very good street tire if you are going to ride on the street after your track ride. If you ride 100% street, then the Q3 is the best. If you are going to ride track and street or just track, the D211GP-A is the best choice.
  11. The tire size is not exact from manufacture to manufacturer and from model to model. So a 200/55 OEM Pirelli my not be the same exact size as the race 200/55 Pirelli or the 200/55 Dunlop Q2. The size on the sidewall is not the exact diameter. I know that the Dunlop D211GPA 190/60 DOT and the KR448/KR449 Dunlop N-Tec Slicks 200/55 are the same diameters as teh Pirelli, and have been used with no issues on the Panigale. By going to the Dunlop you will get the "Dunlop Feel", top of the line N-Tec traction and the enhanced durability that comes with the Dunlop. Also consider that the TC
  12. I'm planning to order some 8477 GPA rears for use at NOLA. I have a couple 5436 GPA fronts already. Any reason I shouldn't use the 5436 front in combination with an 8477 rear? Also, I would like confirmation: the 190/60 GPA rear is not the same dimensions as the 190/55? It seems clear by the public specs but I'm just double checking... 190/55: Width (188.5mm/7.42"), Diameter (647.3mm/25.48") 190/60: Width (191.3mm/7.54"), Diameter (657.4mm/25.92") YES, the 190/60 is a larger, higher performing tire. It will fit, no problem. All AMA teams use the 190/60. It works better
  13. 7455 is med, 8477 is med+ I very highly recommend the 8477 for any track day riding. very grippy, consistaint and last a long time. It also can win an AMA national, like it did in Mid Ohio and NOLA.
  14. What type of riding are you wanting to do primarily? Street performance, sport touring, track days, racing?
  15. I would recommend the following: PLAN A- rent the school bike. your attention will not be on the bike and all that stuff, and you can have good learing day at the school without discraction. PLAN B- get a new set of tires from the school. they are top of the line and your attention will not be on your tires and you can focuse on learing. Don't be penny wise and pound foolish. tires are a cheap date when you consider all the other things you spend $ on to go to a school. They are an importaint factor, get it sorted out early and with quality, then your ride and school experien
  16. Hotfoot, Good to chat with you at the track the other day. I would use the D211GPA 160/60x17. Its an N-Tec construction, so its a better construction than the slick in the 165 sizing. Its also the same width as the Q2 160/60, in fact they come out of the same mould. its made for the 4.5 rim, and the 165 slick is made for 5.0-5.5 riim. The compound is the same as the soft 190/60 D211GPA and the soft USA N-Tec slick, so there is nothing different there. You can match it with the D211GPA 120/70 front or the USA slick 125/80, both of which are identical in actual width and diam
  17. Agreed on this, that is the same thing Will told me. There are different ways to connect the ends, and only certain methods are compatible with being able to flip the tire; for instance if the overlap at the end was cut to a 45 degree angle, you wouldn't want to run it in the direction that could peel back the end of the junction. http://dunlopracing.com/newkr451/
  18. Don't spend $9.50 of you $10 of attention on whether your tires are working good or not. Get new tires and spend your attention what really counts! Learning at the Superbike School! My advice is get new tires. Check with the School, they have deal for students only on Q2s
  19. Paris, I think the 190/55 is better choice. you did good there. As fro pressures, the 4-5 psi rise when hot off the track is normal. you will get that on most any racetrack use of a tire. the hotter they get, the more the rise. As for starting pressure, you need to contact the distributor in Australia directly. I am not familiar with this product in the USA because it is not distributed here. Here is the link: My link They sell and service these tires, so contact them directly. Have fun at the track!
  20. AGAIN: The side that is worn out (or in your case torn), does not magically become new by flipping the tire. You are just using it on a different side. This is not the remedy for a worn out tire.
  21. The 190/55 will perform much better than the 190/50 if its a Dunlop. Its the way to go.
  22. Another question about fit - is it true to say that a tyre warmer should be large enough to be in contact with the rim? I remember hearing something about warmers saying that they shouldn't heat only the tyre, but also the actual wheel to help maintain the temperature? I think you might be splitting hairs on that. the idea is to get heat in the tire. if you are doing that, you have done the job. The rim will get hot just by being in contact with the tire and the air in the tire. I would not try to overthink this.
  23. Are you sure they work okay? I've always thought you want hot warmers? That's funny right there!!! Or should I say "that's a cool joke".
  24. Looks fun. Use your friend's kick stand to break the bead. Then try using 2 tire irons and a barrel. It may be less expensive, but you will not get to drink beers while you make the wooden contraption. Just think of all the bench racing that could go on while you make that thing.
