Superbike Brake Information Video

Updated 5-23

The AXIS/SBK round race rotors are manufactured in a proprietary high alloy stainless steel designed expressly for Pro Superbike teams.  The thicker 6.5mm 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.  Offered in two sizes for most applications: 320mm x 6.5mm and 330mm x 6.5mm. As with the entire range of the patented AXIS series full-floaters, the final operation prior to assembly includes Cryogenic deep freezing to further stabilize the proprietary stainless blades.


The patented AXIS Design floating system is many times stronger than conventional semi-floating brake rotors.  The heart of this advanced design has the floater buttons controlling radial and axial float only.  They are non-load bearing.  All of the considerable braking forces are channeled through the trademarked Direct-Link architecture comprising over an 800% increase in surface area load transfer as compared to conventional brake rotors…simply a superior design!

Where rulebook legal, our billet Iron provides a higher coefficient of friction over stainless, but very importantly, with more feel, feedback and control at the brake lever.

The design elements comprised in our semi narrow-band architecture is specifically optimized for use with late generation calipers.  The thicker 6.5mm blades strategically increase mass at the critical interface.  This substantially improves 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.  They perform brilliantly with the OE traction-control electronics for seamless operation making them a simple bolt on.

Size offerings include:

  • 320mm x 6.5mm
  • 330mm x 6.5mm

 Late model GSX-R Superbike race rotors are available in both the 320mm x 6.5mm and 330mm x 6.5mm


Regarding the size difference (310mm vs 320mm vs 330mm), it all comes down to the mechanical advantage produced by moving the fulcrum point further out for more leverage on the wheel.  There is also the proportional feature of greater thermal capacity created by increased mass and surface area of the larger unit.

The AXIS full-floaters move freely on their carriers.  This reduces brake drag along with design inspired benefits including reduced thermal build, reduced brake fade, improved braking efficiency, and longer pad life.

The AXIS carriers also feature design elements that improves assembly strength by straightening the load path from curvature to linear.  Material here too is very special; we spec U.S. produced Alcoa or Kaiser aircraft grade aluminum only, cut and CNC machined from bar, not stamped. They are then hard anodized to Mil-Spec Type III process for maximum durability.

All BrakeTech AXIS blades employ a CAD optimized CNC machined hole and slot pattern, which maximizes cooling as well as high strength.  Weight minimums are prudently kept in-step with the demands of top-level racing.  While weight reductions are generally desirable, the experienced tuner will not sacrifice reduced rotor mass at the cost diminished braking performance relative to thermal overload (i.e.: brake fade).

The AXIS race rotors feature optimal material mass to deal with the realities and requirements of high thermal load exposure.  Regardless of rotor shape, one of the basic physics of braking is the conversion of kinetic energy into thermal energy; adequate material mass for this process is crucial.

Uniquely, we offer both the AXIS/Iron billet race series rotors our continuous-cast, high tensile strength and (billet machined from bar) Ductile iron, for pro level race use where legal.  The new AXIS/SBK in the round configuration joins with a FIM / AMA – M/A rules compliant new race-spec stainless steel.  With the recently upgraded material system, the Superbike series provides all the critical performance capacities and sought after characteristics making them the logical choice in a winning combination.

Additionally, for Supersport and Superstock racing, the AXIS/Cobra stainless steel series covers those requiring like-material specs for rules compliance in the race venues.  See them in the AXIS/Cobra page.
