Question Question For The Dunlop NTEC Riders

What's the difference between the D209 GPA and the D211's?

Isn't the 209 the AMA spec tire?

Were you using the NTEC's when you ran the '41's at MSRH?

I rode on the 209's earlier this year until the 211's came out, then the "triple compound" came out late in the season and I ran on those because they were alot cheaper than the 211's. I wonder myself, how many different tires does Dunlop have available now (please don't include the 208GP/GPA series). I was on Michelins in 2007 then went to Dunlops in 2008 and ran 22's at Cresson (I still suck) but was doing 25's on the Michelin (I sucked worse then). When I made the switch I didn't even adjust the suspension going from 180/55 Michelins to 190/55 Dunlops.

Wow, that's a pretty significant geometry change from a 180/55 to a 190/55. I had to adjust things just from going from a bt002 to a bt003 due to the height difference.

I totally agree. I actually did the change right before the first race at Oakhill. I went out on the track, on my first practice session I was 3 seconds faster. I found Jim Cambora and told him the switch I did and that I hadn't changed anything as far as geometry. Jim asked me if I liked how the bike felt, I told him "yes" and he said "why change it now, just run it". I didn't change it all season, probably should have experimented but I didn't have the extra time to get the bike up to Jim. The difference in the 180 Mich and 190/55 Dunlop was about 9mm I think, so it made for a faster turning bike.

how would you rate the 209 vs the 211?

I went from Pirelli to Dunlop, and dropped more thab 5 seconds, and 8 seconds over Michelin. I had to make HUGE geometry changes to the bike, but once it was set up, it was like the bike was on rails! I could do no wrong.

I think the 211 is the ultimate tire, however, I think it's priced itself out of the budget racer. When I had the 211's the front felt like it stuck to the track like velcro and knowing you could get on the throttle earlier and harder was a confidence builder. The 211's last a long time as well. I never tucked the front with either tire, always tucked with the Michelin and was going slower (could have been just bad/abrupt inputs to the bike by me though). The Dunlop 209 was the first race tire that I ever made me think to myself "this is what a race tire should feel like", the 211 is even better as far as confidence goes...at least in my head. I would like to try the 003 next year for a couple trackdays.

I switched from Dunlop to Bridgestone several years ago. Dunlop has been the only tire that was able to inspire that much confidence with me until I got on the 003. The 003 IS a slick IMHO, it just has grooves cut in it

It's silly that people pay for Dunlop when they can get the same feel and longevity out of a much less expensive tire, with better support and contingency... my $.02 of course, ymmv.

Anyone figure out all the DOT tire model numbers? 209 GP (JLB construction), 209 GPA, and 211 N-Tech? So is the 209GPA the tire with the new triple compound that came out right before TWS (Texas World Speedway) in Oct or is the triple compound yet another model?

The 209GPA is supposed to be the multi-compound version of the 209GP (the only exception being the European 209GP's which are also a multi-compound).

I don't know about the construction/belt differences between the 209GP's and 209GPA's.

The 211 front is SAID to be the same as the 209GPA front, whereas the 211 rear is an NTEC and the 209GPA rear is a more traditional construction. Why the 211 front is more expensive than the 209GPA is anyone's guess.

I've ridden on both tires and can tell you from suspension set-up to side grip there is a difference. I've heard as well that the 209GPA and the 211 fronts are the same, which I believe is completely false. We compared the two tires side by side and the 211 visually had alot more agressive profile for more edge grip compared to the GPA's. That being said, the GPA's are great tires you just have to have a proper geometry and suspension set-up. Ideally your settings are going to be a little softer than most other tires because the Dunlop is so thick it doesn't flex like per-se a Pirelli carcass does. The 209GPA is the spec tire for every track other than Daytona where everyone will either be on 211's or the KR106 slicks in Superbike.

Well from my perspective, the only times I see you running hard is (a) when you see me ahead of you so that you can make a point of passing me while making rude hand gestures or (b) when you see me coming up behind you so that you can prevent me from passing you, while making more rude gestures. You would probably be fine on any old sport touring tire.

I've ridden both, and as others have said the 211 is a great confidence inspiring tire, the best I have ridden for sure. The price is downright outrageous though, by the end of this season they were nearly $200 more a set then the 209's or 003's.

209's are also great tires, but I have had to change some suspension settings when switching between the two... 209's are the way to go for best price/performance ratio.

the new 209gpwhatever has the the same ntec compounds as the 211, but the proflie is the same as the original 209. the 211 has a much more aggessive profile with more side grip when leaned at the max. the 209 cant lean as far over and has the tendency to wanna wheelie out of a turn

the 209 and 211 wheelie out of turns, the edge drive grip is INSANE!
