call me a moron, but I can't find the topic I started a little while ago about putting dunlop d208gp race tires on my street 01 750. any help would be appreciated

So whats the question? The d208 is a very fine track tire. Yes, it is street legel. Race tires have been proven not to be as efective as a street tire on the street. Several magzine have tackled this subject before. On the track, now thats a different subject. I recently took the new bridgestone bt010 for a track day. I will not make this mistake again. It is a very good tire, but not the best tire for the track. You will not ride you bike on the street like you would a track. Therefore the race tire usually will never heat up to the proper temp to preform as they should. If you live at Deals Gap thats another story. Again, the gp/race tires are best for the track and the high performace/street tire is the best tire for the street. I probably could type another page, and tell you how the different tire structures and designs, make each type tire better suited for its purpose.

Good Luck!

sorry sum but your wrong about half of what you said. i use them on the street and i love them. i deleted the topic because too many people that know nothing about tires filled it with bullshit. read this and most of your questions will be answered. it was written by a dunlop tire rep.

Here is some text from Steve Brubaker on this very subject. Steve is well

FWIW, I've been using race tires on the street since the early '90s. K591, D202, D364, D207, D208, all in race compounds. They work perfectly as street tires, and I can take them to the track too. The only thing they hurt is my wallet when I have to buy new ones.

Ohhhhhh boy! Here we go again. I have used race tires on the street also. I agree they do work. However there have been to many test done that say that the street tire is better for the street. I'm too busy now to look for the many articles that support me. I will bet that if anyone here, would email or call dunlop, bridgestone, or michelen that they will say that the street tire is better for the street than the race tire. They will also tell you why. I am very suprised that more of you guys haven't read these articles. I consantly read just about any motorcycle magazine that I can get my hands on. Like the old saying goes, to much information is better than not enough. I didn't read the reply on what the tire rep said. I believe that if you talk to 5 different EX butt crack tire reps, you will likely get 5 different stories. I've learned to trust a tire rep like I would a used car salesman. Someone do the footwork and post the results.

Bmfgsxr, I could't contradict myself and not read the entire post. This guy doesn't sound like a butt crack like a lot of tire reps. This is some very good info. After reading it though, it sound like you are agreeing with me. The street tire is better suited for the street than the race tire. I also like the one comment that you made about riding so hard on the street, that you think need a race tire. Good info!

P.S. bmfgsxr, I think you should be your own man, dont stand on the shoulders of your brother or father. Erase that silly comment "brother of Hunter" I'm sure this hunter is great, but so are you. Make your own name. Good Luck!
