ISR Brakes from Sweden are very high quality and rugged systems designed for top racers who demand the best performance and durability from their brake systems.  Race proven, all ISR brake systems are CNC machined from aerospace quality billet aluminum and then finished with a clear anodized coating for the ultimate in corrosion protection.  The 6 piston CNC machined calipers from ISR have the highest strength to weight ratio of any aftermarket caliper today.  These kits fit all sportbike, supermoto, Harley, and custom applications utilizing 108mm spacing, sold each (RH or LH) or in sets (RH+LH).



The 22-044 series of calipers were originally designed for high performance applications where original 4 or 6 piston radial mount calipers were used.  The 6 piston radial mount calipers from ISR will seriously enhance your braking performance.  The larger effective radius of the friction area allows a more even distribution of the braking heat and minimizes rotor warpage.  The lightweight design lowers unsprung weight while still maintaining high rigidity delivering and exceptional feel with unmatched braking performance.  The six individual pads allow more edges to bite into the disc resulting in an extremely high friction characteristics.  Each pad has it's own machined pocket that allows for pad retention in the event of pad pin failure, a feature designed as a direct result of Swedish Superbike racing involvement.


The caliper pistons are machined from an aluminum alloy for light weight and are then plated with a very hard Tufram coating designed to minimize wear from long piston life under the most demanding conditions.  The 22-044 monobloc series have the following specifications for motorcycles with 108mm bolt centers and 320mm rotors:

• 30mm x6 pistons
  
• Pistons are made from a Tufram plated aluminum alloy
  
• Pad area is 31.8 square centimeters
• Uses EBC FA175 pads or equivalent
• Swept height of rotor is 33mm
• 320mm rotor size
  
• Rotor thicknesses 4.6mm-5mm
• Banjo bolt size M10 x 1.25mm
• 108mm mounting centers
  
• 1.10kg (2.42lb) weight
  
• Clear anodized

Calipers are sold each (RH or LH) or as a set (RH+LH).  As always please check the dimensions and measure carefully, verify the calipers will fit before purchasing.  The critical dimensions are listed below, please inquire if you are unsure.
