The Ohlins rear shock reservoir, mounted to the footpeg bracket instead of the rear subframe. This location is required due to the rear brake fluid reservoir, although some folks remove the charcoal cannister and put the reservoir in its place.
The preload adjuster is mounted on the left side of the bike, on a special bracket that bolts to the subframe connector bolt. It does block my secondary accessory port. I may bend the bracket to allow access.
Compression damping is adjusted with this knob on the remote reservoir.
The length of the shock (and ride height) is adjusted with the silver and blue nuts. Rebound damping is set by turning the black plastic knob located just above the silver nut.
