## Abstract

Described herein is a stabilizer system to a rider having limited leg mobility to operate a motorized vehicle having one or more wheels. Multiple embodiments are described, with differing embodiments configured for different mounting positions on different types, makes, and models of motorcycle. One embodiment can mount to a rear frame mount of a sport style motorcycle, while another embodiment can be configured to mount to a lower frame mount of various styles and types of motorcycles. Each embodiment can be controlled via a handlebar mounted switch device, which can be used to raise or lower a stabilization system via an electrically and/or hydraulically powered actuator.

## Claims

### Claim 1

An actuated stabilizer system to be installed on a motorized vehicle, the system comprising:
an actuator coupled with an electrical system of the motorized vehicle, the actuator including an electric motor and a piston, wherein the electric motor is configured to cause the piston to extend and retract based on a control input to the electric motor;
a stabilizer bar configured to be mounted to a frame of the motorized vehicle, the stabilizer bar including multiple wheel assemblies and an actuator mount having a single actuator attachment that is offset from the center of the stabilizer bar, the actuator attachment to enable the stabilizer bar to couple with the piston of the actuator, wherein the stabilizer bar is a single u-shaped bar that is rigid and continuous between the multiple wheel assemblies, includes a first portion and multiple second portions, the multiple second portions each including a wheel assembly of the multiple wheel assemblies, and is configured to pivot between a raised and lowered position based on movement of the piston of the actuator, wherein an extended position of the piston corresponds to a lowered position and a retracted position corresponds to a raised position; and
wherein the stabilizer bar is to laterally support the motorized vehicle on at least two sides when the stabilizer bar is in the lowered position.

### Claim 2 (depends on 1)

The actuated stabilizer system as in claim 1, wherein the actuator is a linear actuator.

### Claim 3 (depends on 1)

The actuated stabilizer system as in claim 1, wherein the piston is to be driven at least partially hydraulically.

### Claim 4 (depends on 1)

The actuated stabilizer system as in claim 1, wherein the first portion of the stabilizer bar is configured to be mounted to an upper rear position of the frame of the motorized vehicle.

### Claim 5 (depends on 1)

The actuated stabilizer system as in claim 1, wherein the first portion of the stabilizer bar is configured to be mounted to a lower fame position of the motorized vehicle.

### Claim 6 (depends on 1)

The actuated stabilizer system as in claim 1, wherein the stabilizer bar is configured to be raised and lowered via manual activation of the actuator.

### Claim 7 (depends on 1)

The actuated stabilizer system as in claim 1, wherein the stabilizer bar is configured to be raised and lowered via automatic activation of the actuator based on at least a speed and acceleration of the motorized vehicle.

### Claim 8 (depends on 7)

The actuated stabilizer system as in claim 7, wherein the stabilizer bar is configured to be raised and lowered via automatic activation of the actuator based additionally on a lean angle of the motorized vehicle.

### Claim 9 (depends on 8)

The actuated stabilizer system as in claim 8, wherein automatic activation of the actuator is overridable via a manual switch.

### Claim 10

A motorized vehicle including an actuated stabilizer system, the vehicle comprising:
a frame to which an engine and one or more wheels are attached;
an actuator coupled with an electrical system of the motorized vehicle, the actuator including an electric motor and a piston, wherein the electric motor is configured to cause the piston to extend and retract based on a control input to the electric motor;
a stabilizer bar configured to be mounted to the frame of the motorized vehicle, the stabilizer bar including multiple wheel assemblies and an actuator mount having a single actuator attachment that is offset from the center of the stabilizer bar, the actuator attachment to enable the stabilizer bar to couple with the piston of the actuator, wherein the stabilizer bar is a single u-shaped bar that is rigid and continuous between the multiple wheel assemblies, includes a first portion and multiple second portions, the multiple second portions each include a wheel assembly of the multiple wheel assemblies and the stabilizer bar is configured to pivot between a raised and lowered position based on movement of the piston of the actuator, wherein an extended position of the piston corresponds to a lowered position and a retracted position corresponds to a raised position; and
wherein the stabilizer bar is to laterally support the motorized vehicle on at least two sides when the stabilizer bar is in the lowered position.

### Claim 11 (depends on 10)

The motorized vehicle as in claim 10, wherein the actuator is a linear actuator.

### Claim 12 (depends on 10)

The motorized vehicle as in claim 10, wherein the piston is to be driven at least partially hydraulically.

### Claim 13 (depends on 10)

The motorized vehicle as in claim 10, wherein the first portion of the stabilizer bar is configured to be mounted to an upper rear position of the frame of the motorized vehicle.

### Claim 14 (depends on 10)

The motorized vehicle as in claim 10, wherein the first portion of the stabilizer bar is configured to be mounted to a lower fame position of the motorized vehicle.

### Claim 15 (depends on 10)

The motorized vehicle as in claim 10, wherein the stabilizer bar is configured to be raised and lowered via manual activation of the actuator.

### Claim 16 (depends on 10)

The motorized vehicle as in claim 10, wherein the stabilizer bar is configured to be raised and lowered via automatic activation of the actuator based on at least a speed and acceleration of the motorized vehicle.

### Claim 17 (depends on 16)

The motorized vehicle as in claim 16, wherein the stabilizer bar is configured to be raised and lowered via automatic activation of the actuator based additionally on a lean angle of the motorized vehicle.

### Claim 18 (depends on 17)

The motorized vehicle as in claim 17, wherein automatic activation of the actuator is overridable via a manual switch.
