What is the main benefit of the 5-position preload adjuster?

The 5-position cam-style preload adjuster allows you to easily fine-tune your motorcycle's suspension. You can adjust it to match your weight or riding preferences, ensuring a more comfortable and controlled ride whether you're riding solo or with a passenger.

What makes the damping performance consistent?

These shocks utilize a high-pressure gas charge, specifically nitrogen, within their damping system. This gas charge helps prevent the oil from foaming, which in turn ensures that the damping performance remains consistent, even under demanding riding conditions.

Are these shocks designed for heavy-duty use?

The 412 Series offers both Standard and Heavy-Duty spring options for select applications. This particular model is designed for general cruiser use, but the robust construction and adjustable preload make them well-suited for a variety of riding scenarios.
