Beringer Aeronal Cast Iron Floating Brake disc RoundRef : BGR00177A / 1125121001

The BERINGER Aeronal® floating brake disc (ref. Y21LGBLF) is designed for off-road riders seeking a robust and lightweight component for their motocross machines. Engineered for direct replacement of the original part, it follows the philosophy of floating discs: combining a cast iron track with an alloy hub to minimize weight while maintaining a structure suited to off-road demands.

• Type: floating disc
• Track: cast iron
• Hub: aluminum alloy (offset/flat depending on version)
• Diameter: 297 mm
• Number of holes: 6

The Aeronal® design aims for a weight saving of around 20% thanks to the narrow track and aluminum hub — an advantage for riders who frequently engage the front wheel in motocross. Subtle in aesthetics as well as functionality, this disc fits front setups designed for a diameter of 297 mm and 6 mountings.
