CRITICAL OVERSIZED FITMENT & BIAS-VS-RADIAL WARNINGS:
**Oversized Rim Fitment Note:** When ordering this 150/60R17 tire as an aftermarket upgrade for lightweight sport bikes (such as the Ninja 300, Yamaha R3, or CBR250R/300R) that originally feature a 140/70-17 tire, please note that this 150mm profile is highly recommended over the wider 160mm variation. The 150mm footprint pinches much less on your factory 4.0-inch rim, allowing the tire to retain its correct crown shape for progressive handling while still adding a wider, meaner look.
**Mixing Construction Type Warning:** The Dunlop Sportmax GPR-300 is a dedicated **Radial (R) Construction** tire. If your lightweight motorcycle originally shipped with traditional bias-ply tires from the factory, **do not mix a rear radial tire with a front bias-ply tire**. Mixing tire construction types on the same motorcycle can cause severe chassis instability, unpredictable tracking, or dangerous high-speed tank-slappers. Always replace your tires as a fully matched radial set.
