RFX FXBD 40300 55BK is a front brake rotor designed for Yamaha YZ125 and YZ400F models from 1992 to 1999. Crafted from high-grade stainless steel, it offers durability and resistance to wear. The rotor features laser-cut construction and heat treatment to withstand aggressive braking and excessive pad wear, ensuring consistent performance. The Comaxit coating provides a metal surface treatment that enhances corrosion resistance and appearance. Its CAD-designed profile reduces unsprung weight, contributing to improved handling. The wave design maximizes pad cleaning and maintains optimal brake pad contact, while precision-cut vented holes dissipate heat efficiently to prevent brake fade. This rotor is ideal for competitive and recreational riding, offering reliable stopping power and longevity.
Included in the kit is the rotor itself, manufactured to strict specifications for optimal fit and performance. Installation requires standard tools and is straightforward for experienced mechanics or enthusiasts. Proper maintenance and periodic inspection are recommended to ensure continued braking performance.
