Rear Shock Preload Adjustment (All Models)
WARNING
Adjust both shock absorbers equally. Improper adjustment can adversely affect stability and handling, which could result in death or serious injury. (00036b)
See Figure 1. The Sportster models feature rear shock absorbers that can be adjusted for carrying the weight of a rider and/or passenger.
NOTE
  • XL 883C, XL 883L Low, XL 1200C Custom, XL 1200L Low, XL 1200N Nightster, and XL 50 models have five preload positions.
  • XL 883 and XL 1200R Roadster models have three preload positions.
See Figure 2 and Figure 3. To adjust the rear shock spring preload, turn spring adjusting cam to the desired position with a spanner wrench. When reducing preload, cams should be rotated in opposite direction. A SPANNER WRENCH (Part Number:HD-94820-75A) is available from your Harley-Davidson dealer.
NOTICE
The 883L, 883N and 1200N are designed for solo operation. If you choose to add an adult passenger and/or cargo to the vehicle, the ride quality will be compromised. See a Harley-Davidson dealer for high capacity rear suspension options. (00487g)
