Unlock an unmatched balance of value, longevity, and agile performance with the Dunlop Sportmax GPR-300 Rear Motorcycle Tire, the premier standard for lightweight sport motorcycles. Built with an advanced Radial Construction Technology, this rear tire delivers crisp steering feedback and stable highway tracking without sacrificing mid-season ride comfort. Its specialized tread compound warms up rapidly in cooler weather, maximizing cornering grip and confidence whether you are tackling your morning commute or attacking tight canyon roads.
Part number 45067356 features a 160/60ZR17 sizing profile engineered for a standard 17-inch rear wheel arrangement. Meticulously cross-referenced against factory assembly specifications, this tubeless radial tire serves as the exact factory-spec original equipment (OE) size or premium aftermarket oversized upgrade for the rear position on the following motorcycles:
CRITICAL OVERSIZED FITMENT & RIM WIDTH WARNINGS:
**Oversized Rim Bulge Warning:** When ordering this 160/60ZR17 tire as an aftermarket upgrade for lightweight sport bikes (such as the Ninja 300, Yamaha R3, or CBR250R/300R), please note that your factory rear rim width is tightly optimized for a 140mm tire width. Mounting this wider 160mm radial profile onto narrow 4.0-inch factory rims forces the tire sidewalls to pinch inward. This slightly changes the tire's molded crown radius into a steeper profile, which accelerates center tread wear and causes a heavier steering feel when initiating a lean.
**Suspension Clearance Check:** Mad Lads Moto strongly advises checking the inside spacing of your rear swingarm prior to street riding. Verify that this tire maintains at least 1/4-inch of absolute free clearance away from your drive chain guard, inner rear hugger fender, and exhaust brackets at all suspension compression phases.
