Brake Disc - 120mm

Product Description
A 120 mm brake disc designed for electric scooters and light-duty e-bikes. Compact yet effective, this rotor offers quick braking response with lower weight and easy compatibility for many popular scooter models. Ideal for replacing worn, warped, or insufficient factory rotors, it helps maintain safe and consistent stopping power in urban or mixed terrain conditions.

Main Features

• Made from durable stainless or heat-treated steel to resist corrosion, warping, and stress from braking heat.

• Ventilated and precision-machined design reduces heat and improves braking performance under load.

• Compatible with common calipers and mounting patterns used on scooters with 120 mm rotors.

• Lightweight construction helps minimize added rotational mass and preserves ride agility.

• Designed for easy installation using standard hardware and compatible with both front and rear setups.

Technical Specifications
