Product Description

The 190/55 KR449 slick is being discontinued. 

Good news! it's being replaced by the KR451 slick, which is a much better product, providing higher levels of grip, better lap times and a wider range of compounds.

We highly recommend switching to our newer sizing:

On a 600 with 5.5 rim, use the 180/60 Order Here
On a 1000 with 6.0 rim, use the 200/55 Order Here


The KR451 is superior in every way, and there is no down side to switching.  The KR451 comes in a MED+ compound, just like the 190/55 KR451 giving equal durability.  Additionally the KR451 is reversible (flipable) so you can get even more laps out of the tire when using it for track days.

We highly recommend converting to the new tire on your next order.

As a second alternative, we would suggest the Q4 180/55(for 600s) or 190/55(for 1000s) as a suitable replacement.  You can match it with a slick front or  Q4 front.  But our primary recommendation would be the KR451 as the corner speed, lap times and overall grip level is much better.

  1. Fantastic Traction 5 Star Review

    Posted by on 27th Mar 2017

    Just got back from a great weekend at Hallett racing circuit. First time on N-Tec slicks for Motorcycle Lapping Days on my R-1 and they were fantastic. It was cold outside and had my doubts of riding so dropped some psi and they stuck like glue. Recommend these tires for any track day.

  2. Great track day slicks 5 Star Review

    Posted by on 12th Mar 2017

    Used the 190/55 Medium+ Rear and Soft Front at Jennings GP on 2016 ZX10R in late February. I am in the upper intermediate or lower expert depending on who's in each group. I got 2.5 track days out of the rear with at least one-two more days left on the front. I will be switching to the 200 next time as it is bi-directional and a better compound. My 190 had plenty of tread on the right (Jennings has double the amount of left turns to right turns) when I removed it. If I had the 200 I could have easily gotten another day out of it.
    Customer Service in excellent. They will take the time to answer all of your questions and encourage you to call back and ask more. Shipping was very quick also. I will be buying track day tires from these guys for now on.

    Thanks dunlopracing.com for always coming through! Instead of shipping out tires while it was cold and possibly having an issue with cold tears, Steve held off til it warmed up. Tires came in great condition!

  6. Very good tires 5 Star Review

    Posted by on 24th Oct 2016

    This was my first season as a novice racer/second as a expert and the DUNLOP USA N-TEC SLICKS med+ Was my choice of tire for my 1000cc bike. The grip is really good once the tires get up to temperature, being a smooth rider I had very little spinning. They definitely last longer than others competitors which is a plus for the pocket. Looking forward to try out the med compound for the next season.

    These tires were perfect for my last track session. They never broke loose no matter how early I got on the gas or how late I was on the brakes. They are a great tire

  8. Best slicks ever 4 Star Review

    Posted by on 10th Jun 2016

    These are by far the best racing tires I have ever used. Very consistent performance and great grip in the corners. The traction is excellent, with minimal spin even on hard drives. Also very impressed with their customer support and knowledge. They were aware of my local weather conditions and contacted me to avoid shipping during extreme cold weather to avoid possible cold cracking damage.
