The Series 412 offers a simple and robust solution for those looking to improve the handling of their Harley roadster without breaking the bank. This steel shock absorber, gas-charged and equipped with a 5-position cam preload adjustment, combines durability and quick adjustments to fine-tune the rear behaviour according to load and riding style.

• Reservoir: internal
• Function: standard (gas damping)
• Extended Length: 330 mm (13.00") — measured centre to centre

Installation and behaviour: a shock absorber that is slightly longer or shorter than the OEM can affect the rake angle and steering responsiveness.
