Title:
WIDE MOTORCYCLE SWING ARM ASSEMBLY
Document Type and Number:
WIPO Patent Application WO2003074349
Kind Code:
A3
Abstract:
The swing arm of the current invention is a retrofit assembly for a motorcycle frame configured as in a Harley-Davidson Softail motorcycle, allowing for the installation of a wide rear wheel, having a replacement swing arm assembly (10) that mounts to the outside (42) of a stock frame (20). The replacement swing arm assembly (10) has two swing arms (12) positioned in parallel and joined at one end by a spanning bar (14) attached to each swing arm (12) a distance below frame pivot bolt (24). The other end of each swing arm (12) attaches to an axle (34) on opposites side of a tire (30). Existing horizontal shock (17) system attaches to the swing arm assembly (10) through spanning bar (14). The swing arm assembly (10) installs with minor modifications to a stock frame (20). Additional room for the tire (30) and its operation is achieved by moving attachment of the swing arm assembly (10) outside (42) the frame (20). Even wider tires (30) may be accommodated by either or both moving the path of the belt (18) outside (42) the frame (20) or by flaring the swing arms (12) away from the centerline (3) of the motorcycle (1). Either configuration maintains the integrity of the frame (20) and horizontal shock (17) system.
