## Abstract

An All-Terrain Vehicle with a frame, shocks, and A-Arms. The A-Arms have an arcuate shape to accommodate a shock attached below a centerline connecting front wheel(s). The A-Arms on one end arc around the shock and attach to a spindle and on a second end attach to the frame. The arcuate shape provides additional clearance, beyond a non arcuate shaped A-Arm, when a wheel is turned.

## Claims

### Claim 1

An All-Terrain Vehicle (ATV) comprising;
a frame;
a shock;
a spindle;
a first rearward top A-Arm;
a first bottom A-Arm;
wherein the first rearward top A-Arm has an apex when viewed from a top view;
wherein the first rearward top A-Arm has a first end and a second end and arches around the shock and connects to a portion on the spindle with the first end of the first rearward top A-Arm, wherein the first rearward top A-Arm also arches towards the frame at the first rearward top A-Arm apex and connects to the frame at the second end of the first rearward top A-Arm;
wherein the first rearward top A-Arm is substantially straight when viewed from a front view; and
wherein the first bottom A-Arm arches upwards when viewed from a front view and is substantially straight when viewed from a top view.

### Claim 2 (depends on 1)

The ATV of claim 1 wherein the shock attaches to the spindle below a centerline through a front wheel.

### Claim 3 (depends on 1)

The ATV of claim 1 further comprising a second top A-Arm wherein the second top A-Arm has an arcuate shape and the second top A-Arm attaches to the spindle on a first end of the second top A-Arm and to the frame at a second end of the second top A-Arm and wherein the first top a-arm arcuate shape provides clearance for a front wheel when rearward portion of the front wheel is turned towards center of vehicle.
