Abstract: A single hand tool is utilized to adjust the rear shock absorbers on a motorcycle, such as a Harley Davidson Softail motorcycle, with the motorcycle in a standing position, without requiring jacking or other lifting of the rear wheel of the motorcycle off the ground. The hand tool is a contoured steel plate having a first end serving as a wrench for loosening the lock nut on the shock absorber, and the second end having dowel pins which engage recesses in the shock absorber adjuster plate. The tool has a length short enough to allow the lock nut of the shock absorber to be loosened and tightened without lifting the bike. A handle of the tool between the two ends has finger receiving recesses along both sides.
