What is preload adjustment and why is it important?

Preload adjustment changes the tension on the shock spring. Adjusting it allows you to set the ride height and how the suspension responds to weight, which is useful whether you're riding solo or with a passenger.

What kind of springs do these shocks come with?

These shocks come equipped with progressive rate springs in a black finish. Progressive springs offer a different spring rate as they compress, providing a balance between a softer initial feel and firmer support under load.

Are these shocks filled with nitrogen gas?

Yes, these shocks are high-pressure gas charged with nitrogen. This helps to prevent oil and gas from mixing, which can lead to consistent damping performance and reduce foaming under demanding conditions.

Product Details

When you're looking to dial in the ride on your 2016-2021 Triumph Bonneville T120, upgrading the rear shocks is a smart move. These Progressive 412 Series shocks are built to give you a smoother, more consistent feel on the road, whether you're cruising around town or heading out for a longer ride.

The doublewall steel body construction houses a nitrogen-charged damping system that works with multi-staged, velocity-sensitive valving. This means the shocks react effectively to different road conditions, providing reliable damping performance. You can also fine-tune the ride to your preference using the five-position cam-style preload adjuster. This lets you set the spring tension whether you're riding solo or carrying a passenger, or if you've added extra weight to the bike.

These shocks come with progressive rate springs in black, designed to work with your Bonneville T120. They fit right and offer a solid improvement over stock suspension components.
