Dunlop 209 GPA
These are popping up on eBay and other places, but they're not even on the Dunlop site yet.
They're 190/60, instead of the usual 50 or 55 ratio.
I'm getting some take-off's to try on my 12. Any feedback??
thanks,jeff

A dunlop is a dunlop is a dunlop. I've never heard anyone say a good thing about them.
But let us know how you like 'em, maybe they finally came through with a decent tire.

I have a Dunlop 190/60 but it's a 208gpa....never heard of a 209.
Conman, I love the 208GPA's.

I think the tires that they race with are much different than the ones that they sell Joe Public! PRICKS!!!!!

Dunlops are garbage... not a performance tire at all...

The 209 is the newest GB made DOT race tire, they still make the 208 in Buffalo, NY. The 190 is designed for a 5.5" rear wheel and gives the AMA guys better side grip. I've heard from some pro racers that the front is not better than the 208, so I stayed with the 208s. The tread pattern is totally different so you can't mistake one for the other.

This is the first time ('cept for the stockers...) that I'm running Dunlops. For the price, I figured I'd see if they finally made a sticky tire. They're supposed to be what the AMA guys run, Miguel etc.
I see good things on the 208gpa, we'll see about the 209's. I agree also, that we prob. can't buy what the big dogs run.
I'll be sure to let you all know how they are. I was not aware that they were designed for the 5.5 rim...hope there's no issues with my 12's 6 incher, as with the debate over the 180/55 on a 6 inch rim.

I expect the reference was intended towards street tires; the GPA's are track tires however and so it is not right to apply experience with street Dunlops against them. That Dunlop has made some good track tires is a fact.

I have just wore out a Dunlop 190/60 GPA rear and it was a damn good tire. I had to raise the tripple tree up about 1/4 inch because the rear tire was so tall, And with my 17/48 sprocket combo the gearing was too high imo. A 17/46 is much better since the tall tire changes the ratio considerable.
The wear was awesome. I never seen a race tire wear so well. I expected threads to show about 300 miles ago but they still have not shown up. I am changing it this week.
The bike also leans over quite a bit on the stock kick stand because the tire is so tall, Just be careful of parking on anything soft.
The bike really feels good sitting up that tall. And turn in is really good. I did not have any sliding like the regular Dunlops give ya. They are different and take a little time to get used to. But if the price is right give em a try. They might suit your style of riding.

I agree with Gixx1300R I also did not have any rear tire spin-up on accel. Like previous Dunlops did also to me. I just realized that after reading Gixx1300R post.

Yes, I used them on a Zx-9 and they didn't stick that much better... and went away
TWICE as fast...
Get a clue and realize that synthetic tires are the ONLY way to go.... Dunlops are ancient
technology now...

Ah Mr. Outlaw Sir, I hate to say this out loud but a 17/46 combo would be higher than a 17/48. A taller tire will in fact have a greater Roll out effectively changing the gear ratio to a higher gear. So with that being accounted for you would need more teeth on the rear to keep a constant ratio compared to the tire you just replaced. Removing teeth would only serve to make the ratio even higher. At least where I come from it works that way.

Outlaw, yes the 208GPA... on the Zx-9... track days in FL... and they balled and chewed
just like the pics further up....
Here's what the powers look like after running them hard, on the very edge, for 110
miles today... no cupping, no balling, not even any feathers on the grooves...and the
best part is they didn't slide out like the Dunlop 208GPAs did on the Zx-9
The most I ever got out of the Dunlops were 80-90 miles... I ran these powers today as hard
as I do at track days, meaning I had the bike down to the edge of the tire and drove
hard out of the turns... and look at the pic... it's amazing... no sign of wear...
I'm not trying to be a know it all, or piss anyone off... sorry if I did... I'm just amazed that
the new synthetic tires are that much better than rubber tires...
If you look close, at the lower right of the pic you can see that the tires were all the way over
to the edge, and even the tiny directional arrow can be seen and was not worn off...

Fear IS NOT a Factor!
Try this gunner 46 tooth divided by a 17 tooth = 270
48 tooth divided by a 17 tooth = 282
Take the rear sprocket size and divide by front sprocket size and you have your ratio.

Gunner, is that what the 014 wear like...??? See how smooth the tire still is...???
I ran a new 208 (NOT the GPA) 3 days ago, same exact run, and the tire was completely
shot, with balls coming off and cords showing about 3/4 of an inch from the edge...
I just so amazed that I abused this tire as hard as I could and it held up for 110 miles!!!

No matter how you slice it a 17/48 is a lower ratio than 17/46 and a taller tire will give you a taller ratio as well. you are confused Sir. Your post stated that you went to a taller gear because the tire was a larger Dia and changed your gear. I agree with you it will , but you went the wrong way. Taller tire requires more power OR lower gear ratio to pull.

It will fuzz up just a little Jere.
And outlaw I know how to do math Sir thanks for the lesson anyway. I also know what type of effect a tall tire has on my gearing. 1st gear is short and 6th gear is high. Multiplied less times is higher not lower.

Gunner you're right, I think Outlaw knows what he's doing, he just didn't say it quite right...
Confused me a bit too... but we all know a larger sprocket in the rear will cut down your
top speed but give you better bottom end..
