Description

Öhlins STX Pro Shocks for Adjustable Motorcycle Suspension

Upgrade your motorcycle’s rear suspension with Öhlins STX Pro shocks, designed for riders who want adjustable damping, reliable suspension control, and a setup tailored to their street-riding needs. This pair of shock absorbers features adjustable rebound and compression damping, adjustable spring preload, high-pressure nitrogen gas charging, and hard-anodized CNC-machined components.

With a listed extended length of 12.933 inches and an adjustment range of approximately 0.393 inches, these shocks provide setup flexibility within the manufacturer’s specified limits. They are also listed as compatible with a Tour-Pak, but exact motorcycle fitment and luggage-load requirements should be confirmed before installation.

Öhlins STX Pro Shocks with Adjustable Damping

These Öhlins STX Pro shocks feature adjustable rebound and compression damping, allowing suspension response to be tuned for different road conditions and riding preferences. Compression damping affects how the shock responds as it compresses, while rebound damping controls how it extends after compression.

Correct adjustment can help create a more controlled suspension feel. The ideal settings depend on motorcycle fitment, rider and passenger weight, spring selection, and road conditions. Follow the manufacturer’s setup instructions when adjusting damping.

Length Adjustment for Suspension Setup

The shock absorbers have a listed extended length of 12.933 inches, with a stated tolerance of plus or minus 0.196 inches. The adjustment range is listed as 0.393 inches, or approximately 10 mm. This provides limited flexibility for suspension setup within the approved range.

Shock length can affect ride height, suspension geometry, and handling. Verify the required dimensions and approved adjustment range for your exact motorcycle before ordering or making changes.

Adjustable Preload and Multiple Spring Rates

The adjustable preload system allows the spring’s initial compression to be set according to the motorcycle’s setup requirements. A billet tool is specified for preload adjustment. Proper preload helps establish suitable suspension sag for the rider and intended load.

Multiple spring rates are available, making correct spring selection essential. The supplied part notes list Öhlins spring part number 66420-028. Confirm the correct spring configuration with the manufacturer or seller before purchasing, particularly if the motorcycle regularly carries a passenger or luggage.

Heavy-Duty S2 Spring Requirements

The supplied fitment notes specify two conditions for selecting the S2 spring option:

• The rider must weigh more than 250 lb.
• The combined rider and passenger weight must exceed 500 lb.

Both conditions must be met to use the S2 option. If either condition is not met, the supplied guidance directs customers to select HD 779, not HD 779S2. Confirm the exact spring and shock application with the seller before ordering, as spring selection affects suspension performance and load suitability.

Nitrogen-Charged Shock Absorbers

These STX Pro shock absorbers use a high-pressure nitrogen gas charge as part of their damping system. This design supports the shock’s intended operating characteristics. Proper maintenance and setup are important for consistent performance, especially when the motorcycle is used with varying loads.

Hard-Anodized CNC-Machined Components

The shocks feature hard-anodized, CNC-machined components designed for precision and durability. Their low-friction shaft and seal-head design supports smooth suspension movement, while the overall construction is intended to withstand regular use when correctly fitted and maintained.

Serviceable Design and Tour-Pak Compatibility

The Öhlins STX Pro shocks are described as fully serviceable and repairable, allowing maintenance according to manufacturer procedures. The supplied product notes also state that they fit with a Tour-Pak. Since motorcycle models and luggage configurations differ, confirm exact fitment and load limitations before installation.

Also verify the stated weight range and S2 selection requirements to ensure the correct configuration.
