| 20090085319 | PROGRESSIVE RATE ATV SUSPENSION LINKAGE - A progressive rear suspension linkage is used in the rear suspension of an ATV to aid in ride quality and safety by changing leverage ratio thru the travel of the rear suspension. The rear shock attaches to it as well as to the frame. The linkage system attaches to the frame at one end and to the rear suspension arm at the other end and changes leverage as the mounting point on the frame and the rear suspension arm come closer together or further apart as the rear suspension arms moves thru its travel. This in turn lets some linkages move in a scissors type movement with the rear shock bolted to it at a given point. This invention provides an improvement to the OEM designs, making for improved handling and safer control of ATVs. | 04-02-2009 |
