The fifth generation Dunlop Sportmax Q5S sets the new benchmark for the ultimate street and track-day tire. Following in the development footsteps of the Q5, the Q5S has achieved even higher performance by utilizing aspects from Dunlop's cutting-edge road race tires developed in Buffalo, NY and used in the MotoAmerica Road Race Series. With an enhanced construction, profile, compound and tread pattern, the Q5S provides lighter,nimbler handling, with improved dry and wet grip to make it even more user-friendly, all while maintaining class-leading durability.

• Intuitive Response Profile (IRP) allows for taller tire profile along with tapered sides for a more aggressive turn-tin response and feel
• Front tire profile and construction allows for a 7mm shorter tire, resulting in lighter steering feel and quicker turn-in rate
• Improved polymer compound and softer shoulder performs in both wet and dry conditions
• Optimized tread pattern aids in quick warm-up times and improved wear
• D.O.T.-approved
