Mofun Handlebar Riser Bushing Kit for Harley — Polyurethane Vibration Damper, Stainless Hardware

Mofun Handlebar Riser Bushing Kit is a drop-in vibration damper set designed to secure handlebars and reduce shaking on compatible Harley motorcycles.

If your Harley’s handlebars feel loose, chatter at certain speeds, or transmit too much road vibration to your hands, this Mofun kit offers a straightforward upgrade. Built from heavy-duty polyurethane with solid stainless hardware, the set fits a broad range of Harley models and installs without modification. It’s intended to improve control feel and rider comfort by absorbing vibrations where the riser meets the triple tree or handlebar clamp.

Which Harley models will this bushing kit fit?

This Mofun kit covers many classic and modern Harleys across Softail, Dyna, FXR and Sportster lines. It is compatible with model years spanning several decades, with a few exceptions noted below.

• Compatible: Harley Softail, Dyna, FXR (1973–2017) and Sportster XL (1973–2022).
• Not compatible: 2004–2010 Sportster XL and Springer Deuce models are excluded.
• Confirm fit by comparing your riser dimensions and existing bushings before purchase.

How does the kit reduce vibration and improve handling?

The kit uses polyurethane dampers paired with stainless fasteners to isolate the handlebars from frame and fork vibration. Polyurethane offers controlled flexibility that absorbs high-frequency feedback while remaining durable under load.

• Polyurethane bushings cushion vibrations transmitted through the riser and clamp.
• Solid stainless steel components maintain clamp preload and resist corrosion.
• Result: reduced hand numbness and a steadier feel at cruising speeds.

Is installation difficult and will I need to modify my bike?

Installation is designed to be simple and requires no cutting, drilling, or permanent alterations. The kit is intended as a direct replacement for commonly used riser bushings and includes the parts needed for a standard install.

• Drop-in replacement format — no custom fabrication required.
• Basic hand tools typically suffice for removal and reassembly.
• Follow torque specifications for riser bolts and check alignment after fitting.

What are the kit’s materials and longevity expectations?

Mofun specifies heavy-duty polyurethane for the dampers plus solid and stainless steel hardware. These materials balance resilience and weather resistance for long service life under normal riding conditions.

• Polyurethane resists compression set better than many softer rubbers.
• Stainless hardware prevents rust and maintains clamp integrity.
• Regular inspection recommended after seasonal riding and heavy use.

Who is this for? The Mofun Handlebar Riser Bushing Kit suits owners of compatible Harley Softail, Dyna, FXR and Sportster models who want a quick, durable way to reduce handlebar vibration and improve ride feel. It’s ideal for riders who prefer a non-permanent, bolt-on upgrade that keeps factory geometry intact while offering improved vibration damping and corrosion-resistant hardware. Before ordering, verify your model and year against the compatibility notes, and have basic tools on hand for installation.
