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

The 5-position cam-style preload adjuster allows you to easily modify the spring tension. This lets you dial in the ride height and stiffness to suit your specific needs, whether you're riding solo or with a passenger and luggage.

What makes the damping performance consistent?

These shocks use high-pressure gas charging and multi-stage velocity-sensitive valving. This combination helps maintain consistent damping performance by reacting effectively to different speeds and road conditions.

Are these shocks suitable for heavier riders or carrying cargo?

Yes, the 412 Series offers both standard and heavy-duty spring options, along with the 5-position preload adjuster. This allows you to configure the shocks to better handle increased weight from riders or cargo.
