D> GPA PRO 190/60ZR17 2662

Introduced to the AMA Paddock at the 2014 Mid-Ohio round of the AMA Road Racing championship, the all-new DOT GPA-Pro is a step up in performance—and not just for professional riders. Dunlop’s Bi-Directional Technology and symmetrical tread pattern allow the new GPA-Pro rear to be flipped in rotational direction to get more laps out of the tyre. This versatility helps club racers and track-day riders stretch their tyre budget, especially at racetracks that are harder on one side of the tyre than the other. Better grip and more mileage—the GPA-Pro benefits riders of all levels.

The GP-A Pro also features many innovative tyre construction technologies developed by Dunlop in recent years, including:

• Carbon Fiber Technology (CFT)
• Jointless Tread application
• N-TEC radial tyre construction
• Continuously wound Jointless Band (JLB) aramid-fiber belt
• Continuously wound hex-beads
• Intuitive Response Profile™ (IRP)

Carbon Fiber Technology
The GP-A Pro sidewalls (front and rear) incorporate the same carbon-fiber technology introduced in Dunlop’s Sportmax Q3. This carbon fiber reinforcement element in the sidewalls helps provide exceptional cornering stability and predictable and smooth transitional-steering traits.

Jointless Tread Application
The Jointless Tread application is key to the GP-A Pro bi-directional construction in the rear tyre. Using the process pioneered on the bi-directional KR451 slick race tyre, sophisticated production machinery in Dunlop’s Buffalo, New York plant winds the tyre tread onto the carcass in a continuous strip allowing the rear tyre to be run in both directions.

Symmetrical Tread Pattern
The GP-A Pro incorporates a new, symmetrical tread pattern on both front and rear tyres, which was developed through real-world race testing at tracks around the country and the Dunlop Proving Grounds in Huntsville, Alabama. Compared to the previous-generation D211 GP-A, the “land-to-sea” ratio of the GP-A Pro tread pattern places appreciably more rubber down in the working area of the tyres to offer enhanced performance.

Intuitive Response Profile
This rear-tyre technology incorporates steep sidewalls for a unique tyre profile that helps enhance steering response, feedback to the rider and overall cornering stability. Intuitive Response Profile (IRP) offers greater latitude in line choice while cornering and offers amazingly linear steering at various lean angles.

N-TEC Construction
Beneath the tread, the carcass incorporates many of Dunlop’s high-tech advancements including hybrid N-TEC construction. N-TEC combines the benefits of compliant cut-breaker construction with stiffer, continuously wound aramid-fiber Jointless Band construction, and was first designed specifically for racing applications.

Continuous Wound Hex Beads
Like the Q3 and D211 GP-A, the GP-A Pro also features Dunlop’s continuously wound hex beads. This hex bead offers enhanced feel as the tyre nears its cornering limits. They are also light and strong, which offers a benefit to steering response and cornering stability.

The Dunlop Advantage
Dunlop’s commitment to advancing the state-of-the-art in road race tyres never ceases. As the exclusive spec tyre provider in AMA Pro Racing since 2009, Dunlop can access the best riders in the country to inspire continuous tyre development. The new machinery and manufacturing capabilities added to Dunlop’s Buffalo, New York manufacturing plant—the only motorcycle tyre plant in the U.S.—gives Dunlop the capacity and flexibility to develop and manufacture new tyre technologies. The Dunlop Proving Grounds in Huntsville, Alabama—the only motorcycle-only tyre testing facility in the U.S.—gives Dunlop dedicated development advantages in various conditions. This combination—a close working relationship with top road racers, a high-tech manufacturing plant and a dedicated proving grounds—add up to a unique development advantage that created the revolutionary Sportmax GP-A Pro.
