BrakeTech Axis Cobra Race Spec Stainless Steel 320 x 6mm Rotor Kit for 2015-21 Yamaha YZF-R1 / R1M / R1S

BrakeTech AXIS/Cobra™ series extreme performance stainless steel rotors are designed for the demanding enthusiasts and racers alike! The Cobra full-floaters feature premium / proprietary 400 series stainless steel alloy, heat-treated in a optimized petal design that offers style and performance with none of the downside associated with exaggerated wave type rotors. The patented AXIS Design bristles with many new and innovative features making them substantially stronger and with much improved thermal transfer capabilities than any other competitive brand.  All of the considerable braking forces are channeled through the trademarkedDirect-Link™ architecture, comprising over an 800% increase in surface area load transfer as compared to conventional floating brake rotors…simply far superior by design!

The thicker 6mm design strategically increases mass at the critical interface, substantially improving their ability to deal more effectively with the high thermal loads encountered in top level racing.  Another benefit is greater consistency in braking performance throughout a race from start to finish.
