Dunlop Sportmax Q4 Rear Tire Item # 620266
Description
Introducing the all-new Sportmax Q4. Bold look, bold performance for bold riders. A purpose-built track-day tire achieves lean angles up to 62 degrees! More than any other street-legal tire Dunlop has ever made.
Built specifically for the track, and upon the legacy of the Q2 and Q3, the Dunlop Q4 Sportmax tire continues to push the performance capabilities of a street legal tire. Dunlop's engineers have utilized a new tread pattern that increases the contact patch during extreme lean angles and updated compounds that provide better grip than the Q3+ at all temperatures. Dunlop was able to reach lean angles up to 62 degrees, which is more than any other street legal tire they offer.
Riders on high performance motorcycles looking for the next generation of track day tires should look to the Dunlop Q4 Sportmax tires.
