Galfer DF838QS 12.5" Oversized Front Cubiq Semi-Floating Motorcycle Brake Rotor

The Galfer DF838QS is a 12.5" oversized front semi-floating brake rotor featuring Galfer's patented Cubiq® design, engineered for riders who demand more stopping performance than a stock brake system can deliver. Precision-manufactured at Galfer's factory in Spain, this rotor delivers a significant upgrade in braking feel, modulation, and overall brake torque.

Cubiq® Rotor Technology:

• Constructed from a proprietary blend of virgin high-carbon 420 stainless steel for superior durability and heat resistance
• Laser cut — never stamped — for precise, consistent geometry
• Double disc-parallel ground to ensure perfect flatness and even pad contact
• Heat treated to each specific application for optimized performance
• Semi-floating design reduces heat transfer to the wheel hub and accommodates thermal expansion
• Unique Cubiq® rotor shape promotes uniform brake pad wear by maintaining consistent pad-to-disc contact through every revolution
• Up to 40% lighter than standard round rotors, reducing unsprung weight and gyroscopic effect for improved maneuverability
• Oversized 12.5" diameter increases braking leverage and stopping power over the stock rotor
• Bolt-on design compatible with the stock hub pattern — bracket not included

KBA and TÜV approved for quality and safety. Full installation instructions are included. This rotor is designed for street, track, and off-road use and seamlessly replaces the OEM rotor without modification.
