The Beringer Aerotec caliper is CNC machined from billet aluminum and anodized for an attractive finish. It's a bolt-on fitment for bikes like the FS450 that use a radial fork bottom.

Longer life, perfect for endurance racing or track day rider who wants more life out of their pads! NOT FOR STREET USE! 1100S - Sport - Perfect for street use, does not require heating up like the race pads. For Single Caliper Use (Supermoto), We Recommend: Beringer Aeronal Cast Iron Rotor Radial mounted caliper offers flexibility for rotor size. Use it with a 310mm rotor, or add spacers to fit a 320mm rotor. Spacer requirements vary depending on application. Beringer Aerotec Master Cylinder Pump For good feel and modulation, we recommend the BRO10 which uses a 14.5mm piston. You can trail on and off the brakes really easy and modulate the brakes with confidence. If you prefer a really stiff lever feel, there are a few riders who like the BRO12 with its 17.5mm piston. However, you do lose some of the feel with this stiff setup.
