Technical Data and FAQ

Which compound should I use at a specific track?

The answer to this question is dependent on numerous factors; riding style, set-up, temperature and conditions, type of motorcycle or displacement etc. Also, whether you want a quick lap time during a sprint race or consistent lap times over many sessions such as at a trackday must be considered.

By using the guidelines below, we can help guide you in the right direction of choosing the appropriate Dunlop product.

2662 DOT and Slick (soft): This tire is best suited for dry conditions on days that are minimally 20 degrees C. This tire will produce the best outright grip and lap times in these conditions, but will only do it for a short period of time i.e race distance.

7455 DOT and Slick (medium): is our most universal tire and biggest seller. It is durable, long lasting and produces good lap times for all skill levels. It is recommended at all our Canadian tracks under all dry weather conditions.

8477 DOT and Slick (Medium +): This tire is on average, produces slightly slower lap times than the 7455 compound, but is the most adored trackday and racing tire for its longevity and ease of setup.

Pro 6 Cycle stocks the appropriate compounds for Canadian tracks. Please refer to our pricing for available tire sizes.

What is the difference between the GP and the GPA?

The 211 GPA is made in the US factory in Buffalo, NY. The GP is made in England factory in Birmingham, England. Both are N-Tech construction, low pressure and zero growth tires.


What compound of tire is better in hot versus cold weather?

As a general rule, softer compounds cold tear more easily. In the cold weather, you should run a compound that is more hard than soft.


How many Heat Cycles can I get out of a tire?

Heat Cycles are not an issue with Dunlop racing tires as it would be with other brands. The more important factor is how much tread is left on the tire.

Stable fact: thicker rubber has more grip and develops more heat, thinner rubber has less grip and runs cooler.

After each session you have less grip. As the tire wears out, you have less and less grip. It could be slight or it could be large. Some riders call it heat cycling, but, in actuality, it is the rubber getting thinner and thinner.

It truly depends on how much the tire is worn out, and your specific demands for grip that determines when the tire is not usable for you.


How much life can I get out of my tires?

Using the data above regarding Heat Cycling, it’s really your judgment call. There are too many variables such as the bike size, bike setup, track, weather conditions, riding style and much more.


How old is too old for a race tire?
