Mounting Hardware is included.

Compatable with airheads originally equiped with solid mount Brembo

       Also sold as a dual kit at a discount. Brake calipers, rotors and brake hoses are not included with this set. Brake hoses will require a 10mm banjo fitting at the caliper end, so the metal pipe can nolonger be used.As a single brake this system works well with the original 13-15mm master cylinder. With a dual set up a 17mm OEM mastercylinder (34 31 1 234 379) should be used or an upgrade to an 18 or 19 mm bar mounted system from a newer motorcycle. Brembo radial piston calipers provide the best clearance for spoke wheels. But will require a 16 to 19mm Master Cylinder for dual use. 16mm MC's will work with calipers that have 30mm pistons or smaller like the Brembo M50. This design is for use with European 4 piston calipers with 100mm bolt spacing. 


    Calipers Tested:

    BMW S1000RR 2009 -18 perhaps other years.  These have 34/34 pistons and a slim design that provide lots of clearance for spoked wheels

    34 11 7 714 783 Left  and 34 11 7 714 784 right.

    BMW R1200 1250 S1000XR 2001-2020

     34 11 8 556 205 Left and 34 11 8 556 206 right

    Dual Ducati 1098,696,796,and 848 2010-13 (perhaps other years) Brembo radial 32mm 4 piston calipers will work with a 16mm Master Cylinder but will feel soft. 17mm (34 31 1 234 379) to 18 would be better for dual use. 13 to 14mm OEM Master Cylinders ar perfect for a single brake.

    Several other European calipers will probably work, the above are what I have been able to test. 

    Rotors  note: do not use ABS rotors

    2002-2007 Ducati 749, 848, 999 rotors are 320mm.
