R100RS DUAL KIT WITH METAL GEAR ROTORS: RADIAL (EUROPEAN) ADAPTER SET
This simple bolt on adapter set allows you to replace the original Brembo 2 piston caliper with modern radial 4 piston calipers and 320mm floating rotor used on Ducati sport bikes. This designs works with OEM spoked wheels, snow flakes, Lester's or Morris aluminum rims.
Mounting Hardware is included. Rotors are included in Black or Silver.
Compatible with airheads originally equipped with solid mount Brembo calipers.
34 11 1 241 555, 556
or 34 11 1 464 850 (without pads) axial mount calipers.
Brake hoses will need to be fabricated to fit banjo bolt mount only radial calipers.
a 15mm or larger Master Cylinder is recommended for dual brakes.
Brake calipers sold separately on this site. European 100mm bolt pattern only. 32mm 4 piston radial calipers or smaller are recommended for dual brakes with a Master cylinder size of 15-17mm. 34mm piston radial calipers for 17mm MC and above.
FITMENT
Fits these models (perhaps others) with solid mounted Brembo calipers.

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 an 18 to 19mm Master Cylinder for dual use. This design is for use with European 4 piston calipers with 100mm bolt spacing.

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.
