The invention relates to a floating brake disc (1), particularly for a motorcycle, particularly an off-road motorcycle, which comprises an outer ring (2) which carries a brake band (23) and an inner ring (3) via which the brake disc (1) is connected to a wheel of the vehicle. According to the invention, at least one region (5) of contact, in particular a number of regions (5) of contact, between the outer ring (2) and the inner ring (3) is/are formed on a circular arc (6) extending, concentrically with the brake disc (1), between the outer ring (2) and the inner ring (3), the outer ring (2) and inner ring (3) being connected to one another in the at least one contact region (5) with at least one connecting means (16), in particular a rivet. The inner ring (3) also has, next to the at least one contact region (5), a projection (7) which engages in an indentation (8) in the outer ring (2) in such a way that a bearing surface (9) between the inner ring (3) and the outer ring (2) can be formed, at least when the brake disc (1) is in operation in a vehicle, particularly a motorcycle.

1. A floating brake disc comprising: an outer ring having a brake band; andan inner ring via which the floating brake disc is to be connected to a wheel of a vehicle, wherein:said outer ring and said inner ring have a number of contact regions between the outer ring and the inner ring;the contact region is formed on a circular arc extending between the outer ring and the inner ring such that said contact region follows said circular arc;the contact regions are arranged concentrically with the floating brake disc;the outer ring and the inner ring are connected to one another in the contact regions;the contact regions have at least one connecting means, in particular a rivet;the outer ring has an indentation;and next to the at least one contact region the inner ring has a projection which engages in said indentation in the outer ring in such a way that a bearing surface between the inner ring and the outer ring is formed, at least at times when the brake disc is in operation in said vehicle;wherein there is a clearance between the projection and the indentation, the clearance being formed such that there is no substantial contact between the projection and the indentation until the bearing surface is formed by a relative movement, during a braking operation, between the inner ring and the outer ringand wherein during an unbraked operation of the vehicle the bearing surface is not formed and substantially all force transmitted to the outer ring from the inner ring is transferred via the at least one connecting mean. 2. The floating brake disc according to claim 1 wherein: the projection has an edge; andthe indentation has an edge;the edge of the projection on the inner ring extends radially and the edge of the indentation in the outer ring is configured in a corresponding manner to the edge of the projection, so that a radial bearing surface between the inner ring and the outer ring is being formed. 3. The floating brake disc according to claim 1, in which the inner ring has, in the region of the projection, perforations which follow a shape of the projection. 4. The floating brake disc according to claim 1 in which a number of contact regions are formed which are distributed evenly over the circular arc. 5. The floating brake disc according to claim 1 in which on the outer ring there are openings which are constructed in such a way that force is conducted towards the inner ring during the braking operation. 6. The floating brake disc according to claim 1 in which the floating brake disc has an outer contour which deviates from a second concentric circular arc. 7. The floating brake disc according to claim 1 in which the outer ring, the inner ring and the contact region are concentric. 8. The floating brake disc according to claim 3 in which the perforations are wedge-shaped perforations. 9. The floating brake disc according to claim 1 in which the perforations have corners, said corners being rounded. 10. The floating brake disc according to claim 5 in which slots and/or hole-like openings are placed in the brake band of the outer ring. 11. The floating brake disc according to claim 6 in which the outer contour is an undulatory outer contour. 12. A floating brake disc comprising: an outer brake disc ring having a brake band for contacting brake pads;an inner ring via which the outer brake band is connected to the wheel of a vehicle;a plurality of contact regions between the outer ring and the inner ring for attaching the outer ring to the inner ring, each of the contact regions comprising:on the inner ring: a circular arc segment which is concentric to the inner ring and a projection extending adjacent the arc segment in a radial direction; andon the outer ring: a circular arc segment which is concentric to the inner ring and a projection extending adjacent the arc segment in a radial direction so as to be complementary to the contact region on the inner ring; anda fastener disposed in the contact region to attach the inner ring to the outer ring;wherein there is a clearance between the inner ring and outer ring such that braking force pushes the inner ring projection and outer ring projection against each other. 13. The floating disc of claim 12, wherein, for each of the inner ring contact regions, the projection extends radially outwardly from the arc segment. 14. The floating disc of claim 12, wherein the fastener is disposed between the inner ring and outer ring in the contact region and is disposed in a direction parallel to the axis of the brake disc to hold the inner ring and outer ring in a generally planar arrangement.
