Engineered for aggressive off-road and recreational riding, the Storm DF-3006 brake disc rotor​ delivers reliable, fade-resistant stopping power when you need it most. With a 220mm outer diameter​ and a 58mm center bore, it's precision-machined to OEM tolerances for a direct bolt-on fit—no modification required.The 4-hole bolt pattern​ (Φ8.5mm apertures on a Φ76mm pitch circle) matches the front wheel hubs of most 150–250cc ATVs, pit bikes, dirt bikes, go-karts, and scooters. At 4mm thick, the disc balances heat dissipation and structural rigidity, while the hardened steel construction resists warping under repeated heavy braking.Pre-drilled, surfaced, and ready to install—just bolt it on and ride.
