These remarkably lightweight and patented full-floaters weigh in at a stealthy 640g to 680g, depending on application.

Unique in design and appearance, the AXIS rear floaters will be a limited premium line intended for late model European and select Japanese Sportbikes (for use with OE calipers).  Incorporating our patented floating architecture which is the hallmark of our AXIS front floaters, these lightweight 100% billet units weigh at 10-35% less than the OE units.  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 floating brake rotors...simply far superior by design!  Our race-spec ductile iron units improve overall brake response with not just more power but strategically, considerably improved control and modulation at the brake pedal (as well as reducing brake drag). 

Granted, rear brakes have historically not been a significant player in the Sportbike market, but never before has a truly innovative full-floating rotor been developed and targeted for this application.  With it's distinctive design, improved performance parameters and huge weight reduction, we bring an entirely new dimension to this element of braking technology.

Intended for use with OE calipers, the new AXIS/Rear floaters will be offered for nearly all late model European and select Japanese Sportbikes.                             NOTE:  Requires rear wheels with "Post" type mounting face that allows adequate space for the bobbins to extend through the backside of the center carrier.  Will not fit on the following OE rear wheels (without user end modification to the wheel) but rather are intended for use with the full range of Aftermarket wheels employing the OE mounting pattern:
    •    Honda CBR's
    •    Suzuki GSX-R's
    •    Yamaha YZF-R1 & R6

SPECIAL NOTE:  All Japanese Sportbikes with Nissin calipers require a small amount of relieving of the OE caliper bracket to provide clearance for the floater button flangehead.

The all-new AXIS Rear Floaters are the perfect upgrade for those moving to the higher performance Brembo HPK Billet rear caliper conversion kits.

Units for the Ducati 1098/1198 and HyperMotard, M1100, 848 series includes the requisite speedo sensor triggers.  ABS models in the 4-hole mount series are set-up to accept the OE sensor ring.

AXIS/Iron Black GunKote:  This is a rust inhibiting coating which is thermally bonded on to minimize corrosion.  It must be cleared from the pad sweep area before the rotors become fully functional.  Please click here for the one page instruction guide:  AXIS Iron Rotor Clearing instructions

 Entirely made in the U.S.A.

 • Red bobbins are standard (blue and black optional).

Brake Pad recommendations: utilize either the Ferodo Platinum organic or for a more responsive rear brake, the HH-rated SinterGrip ST brake pads.
