DUNLOP Sportmax GPR-300 120/70ZR17 Front Motorcycle Tire — Radial Sport Performance, Wet Grip

The Dunlop Sportmax GPR-300 120/70ZR17 is a performance-focused front radial tire built to deliver responsive handling and dependable wet and dry traction for small-displacement sport motorcycles.

Designed for street-oriented sport riding, the Sportmax GPR-300 brings radial construction and sport-derived tread styling to bikes like the Honda CBR250/300, Kawasaki Ninja 300 and Yamaha R3. It combines a modern casing profile with belt technologies developed by Dunlop to stabilize the contact patch and improve steering feel without sacrificing everyday durability.

How will this tire change steering and cornering feel?

The GPR-300’s radial construction and optimized carcass geometry sharpen turn-in and make steering more consistent across a range of lean angles. Riders notice a more predictable front-end response that helps confidence on twisty roads and in urban maneuvers.

• Radial casing for improved lateral stiffness and quick steering.
• Profile tuned for smooth transition from upright to leaned positions.
• Sport-derived tread aids stability during mid-corner corrections.

Will it perform well in wet conditions?

The tread pattern is designed to evacuate water and maintain contact on damp pavement, reducing the risk of slipping compared with worn or purely street touring tires. While not a rain-specific tire, its compound and groove layout help preserve grip in typical wet-city or rainy-road scenarios.

• Aggressive groove design channels water away from the contact patch.
• Rubber compound balanced for wet and dry performance.
• Consistent tread contact helps maintain braking traction on wet pavement.

What technologies ensure stability and longevity?

Dunlop applies advanced belt and casing techniques to keep the contact patch uniform and reduce irregular wear. The Sportmax GPR-300 benefits from lessons learned in Dunlop’s JLB and continuously wound belt designs, producing smoother high-speed behavior and predictable wear patterns.

• Advanced belt design for consistent footprint and reduced fatigue.
• Engineered carcass for even pressure distribution across the tread.
• Durable compound formulation for practical life on road-oriented sport bikes.

Which motorcycles and fitments is this 120/70ZR17 tire suited for?

• OEM fit for Honda CBR250 and CBR300 models.
