BMW S1000 RR R XR Dual Sprocket 45T Pitch 525 Black ZF Inner Diameter 110 Bolt Circle 130.8

The ZF Dual sprockets are among the highest quality and most technologically advanced sprockets in the world.

The secret lies in the combination of the durability of steel and the lightweight nature of duralumin.

This aluminum alloy is characterized by enormous strength and density as well as low weight.

The tensile strength is about 11 times that of pure aluminum.
Through hardening, duralumin achieves almost the strength of steel.

As a result, a lower weight and higher durability have been achieved.

Milled grooves in the base of the sprocket ensure optimal self-cleaning.
These grooves prevent dirt from accumulating between the teeth, thereby reducing wear on the chain and sprocket.

The durability of the ZF Dual sprockets is approximately three times longer than that of pure aluminum sprockets and they are 50% lighter than steel sprockets.

Perfectly suitable for both road and off-road use.
