## Abstract

A motorcycle suspension system comprising an axle block on each side of the motorcycle, each axle block for receiving one side of a rear wheel axle, and each axle block rotatably connected to a motorcycle frame member with a bearing. Each axle block may be rotatably connected to the rear wheel axle with a bearing.

## Claims

### Claim 1

An axle block comprising:
a body configured to receive a motorcycle rear wheel axle in a first axial alignment along a first axis;
a first recess in the body configured to receive a first bearing;
a first through hole in the first recess aligned on a second axis, said second axis parallel to and spaced a first distance from said first axis;
a second recess in the body configured to receive a second bearing; and
a second through hole in the second recess aligned on a third axis, said third axis parallel to and spaced a second distance from said first axis.

### Claim 2

An axle block comprising:
a body comprising;
a first aperture configured to receive a horizontally disposed axle on a first axis;
a second aperture configured to receive a first horizontally disposed bearing on a second axis, said second axis parallel to and spaced a first distance from said first axis; and
a third aperture configured to receive a second horizontally disposed bearing on a third axis, said third axis parallel to and spaced a second distance from said first axis.

### Claim 3

An axle block comprising:
a body having an aperture for receiving a motorcycle wheel axle on a first axis;
a first bearing connected to the body and aligned on a second axis so as to provide a pivotal connectability with a motorcycle frame on a pivot axis aligned on said second axis, said second axis spaced a first distance from said first axis; and
a second bearing connected to the body and aligned on a third axis so as to provide a pivotal connectability with a motorcycle frame on a pivot axis aligned on said third axis, said third axis spaced a second distance from said first axis.

### Claim 4

An axle block comprising:
a body;
a first bearing having a first inner race and a first outer race, said first inner race and first outer race concentrically aligned on a first axis;
said first outer race connected to the body;
said first inner race configured to receive a rear wheel axle; and
a second bearing aligned on a second axis for connecting the axle block to a frame pivotally about a pivot axis aligned on said second axis, said second axis spaced a first distance from said first axis; and
a third bearing aligned on a third axis for connecting the axle block to a frame pivotally about a pivot axis aligned on said third axis, said third axis spaced a second distance from said first axis.

### Claim 5

A motorcycle suspension system comprising:
an axle block configured to receive a wheel axle on a first axis;
a first bearing connected to the axle block, said first bearing disposed a first distance from said first axis; and
a first rear-terminal frame member connected on its axle side to said first bearing;
a second bearing connected to the axle block, said second bearing disposed a second distance from said first axis; and
a second rear-terminal frame member connected on its axle side to said second bearing.

### Claim 6 (depends on 5)

The motorcycle suspension system of claim 5 wherein the first bearing comprises an outer race connected to the axle block.

### Claim 7 (depends on 5)

The motorcycle suspension system of claim 5 wherein the first bearing comprises an inner race connected the frame member.

### Claim 8 (depends on 7)

The motorcycle suspension system of claim 7 wherein the first frame member comprises a shock absorber.

### Claim 9

A motorcycle suspension system comprising:
an axle block;
a wheel axle connected to the axle block with a first connection, said axle aligned on a first axis;
a first frame member pivotally connected to the axle block with a second connection, said second connection being a pivoting connection having a pivot axis spaced a first distance from said first axis; and
a second frame member pivotally connected to the axle block with a third connection, said third connection being a pivoting connection having a pivot axis spaced a second distance from said first axis.

### Claim 10 (depends on 9)

The motorcycle suspension system of claim 9, wherein the wheel axle is rotatably connected to the axle block.

### Claim 11 (depends on 10)

The motorcycle suspension system of claim 10, wherein the first connection comprises a first bearing.

### Claim 12 (depends on 9)

The motorcycle suspension system of claim 9, wherein the second connection comprises a second bearing.

### Claim 13 (depends on 9)

The motorcycle suspension system of claim 9, wherein:
the first connection comprises a first bearing and
the second connection comprises a second bearing.

### Claim 14 (depends on 9)

The motorcycle suspension system of claim 9, wherein the first frame member comprises a shock absorber.

### Claim 15 (depends on 14)

The motorcycle suspension system of claim 14, wherein the second frame member comprises a shock absorber.

### Claim 16 (depends on 9)

The motorcycle suspension system of claim 9, wherein:
the first connection comprises a first bearing;
the second connection comprises a second bearing; and
the third connection comprises a third bearing.
