Cool Dunlop N-Tech Slicks - ROCK!!!

During my last NESBA track day on July 5th, I purchased a set of Dunlop N-Tech Slicks from Ron Hix. They were take-offs from his AMA Sprint at Road America. Considering Ron has about 180 HP, and I'm only pushing about 80 HP on a good day, I figured I could still get a bit of use out of them.

Ron had spoken highly about them and how well they grip and how stable they are. I was a little sceptical wondering if i could really benefit from them since I'm only in the I-group with NESBA, but I figured they were a good price, and I'd give them a shot.

I was concerned about the clearance due to the larger size (195/65-17), but I spoke with Tom, the Dunlop rep, and he said they should work even with the 5.5" wide rim on my older gixxer. I got them mounted, the clearance was fine, and then I dropped the Penske's ride height about 4mm due to the larger diameter. Nothing to do but wait for my next track day.

Prior to this, my best personal lap time was a 1:21.18. I was consitent 1:22's.

Yesterday, I went back to Blackhawk farms with a friend (c.b. on here) and we ran the PTT Advanced Group. I started off and the first theng I noticed was a slight difference in the turn-in of the bike due to the different profile. Not bad, just different. After about 3-4 laps, it was all good, and it was time to play.

Dave and I were railing all day, and actually managed to not get passed by a single person. I'm not trying to be arrogant, it's just the way the day worked out. I not the fastest by any means. We managed to run consitent 1:20's and had quite a few 1:19's. My personal best for the day was a 1:19.36. I was pumped! Nothing like going out and knocking 2 seconds off of your lap times.

The Dunlop slicks did EVERYTHING I asked them to do, even if I was probably asking too much from them, and the whole time, they stuck like glue to the track. There were times I was trail-braking going into T-1, 3, 6, and 7 that I just knew I was about to be tossed on my ass, but the tires held, and inspired the confidence to push just a bit harder than I normally would have. The bike felt planted, and made the whole day one of the most enjoyable track days I've had in a long time. The grip gave me the confidence to capitalize on any given opportunity to pass even if it meant I had to brake hard and trail brake while taking the inside line at my normal pace.

Confidence in the tires probably has more to do with it, but those are some kick-ass tires. I would highly recommend giving the Dunlop slicks a try if you get the chance. You won't be disappointed.

Sorry to be long winded, but I thought the background info would help put my experience into perspective. I wasn't sure whether to put this in the NESBA or PTT forum, so I just put it here.

Sweet dude, congrats on the lap times. I'm looking forward to getting passed by you at the next Nesba day!

So, at what point to full slicks become a better option than something like DC3's on a track only bike?

I've been told that keeping heat in them can be a problem. Is that true for anyone?

I'm not sure about your first question. For me it was about gaining the confidence to push beyond where I was on my plateu. They did their job.

As far as heat... I'm running tire warmers now, so heat is taken care of. The Dunlop rep said to make sure they're heated for at least 45 minutes at the start of the day, and then just the normal warmer use ofter that. The slicks work best when they are HOT (165-175 degrees ? ). As long as you give them time to heat up without warmers they'll be fine, but you could probable get some cold tearing due to the surface being hot, but the core of the carcass still being colder. If the rim is warm while they're on the warmers, then the carcass is heated completely.

Maybe someone with more knowledge about the N-Techs themselves will add some usefull info to this. I just know they worked "for me". Other than that, I might just be full of shiot.

I'm not a fan of street / trackday tires, never have been. I'm of the opinion that more grip is always better, therefore I recommend race tires. If you don't have warmers, take it easy for the first lap to get heat into the tires before putting the hammer down. If you are not "fast enough" to keep them up to operating temp, then adjust the tire pressure so they heat up more easily.

All the manufacturers make good race tires, but from my experience I feel Dunlop makes the best race tire. It wears like iron and just keep giving out grip lap after lap, day after day ... far beyond the wear bars. When it does slide, it is extremely predictable and confidence inspiring.

If you do a lot of track days, buying the Dunlops will actually save you money because you will not have to purchase so many tires.

Never met you but man congrats on 1:19!

As a fan of the late 90s style bikes like your GSXR, YZF750, ZX7R styles it's good to see you railing out there with the newer bikes!

Thanks for the props

Here's a 2 lap video from the last session of the day. I had a lot of clear track and tried to make the most of it. When I went frame by frame with the video timer, I was shocked when I saw the first lap here was a...

1:19:00 The second lap is a 1:19:14.

Dammit! So close to an '18

No matter what, it was a great day to be on the track. Dave, you should have come out that last session. You missed a great one.

This was also a day that we had dedicated to Ashwin. Maybe he was helping us out with our times

^^^ I don't think they held me up that much. I'm happy with the times I got.

It does give an excellent example of why you should stay to the inside until clear of the turn when you're "blending" into traffic. If it wouldn't have been one of the Learning Curves instructors (I think it was Rick Breuer), I don't think I would have kept the pace through there like I did.
