Product Information

Full details

The Thrashin Supply Co OG 25.4mm 1" Handlebar Riser Top Clamp is designed for motorcycle enthusiasts who own existing Thrashin Supply OG handlebar risers and seek to add functional mounting points to their setup. It offers the key benefit of providing integrated 1/4-20 drilled and tapped holes on the underside, allowing for cleaner wire management or auxiliary accessory mounting. A notable caveat is that this product does not include mounting hardware, and it is unnecessary for users who already possess newer generation Thrashin risers that come with these pre-drilled holes from the factory.

Extended Product Information

FAQs

Does this clamp include the bolts to attach it to the riser?

No, this product is the top clamp only and does not include mounting hardware.

Is this compatible with 1.25-inch handlebars?

No, this specific model is designed exclusively for 25.4mm (1-inch) handlebar diameters.

Where is this product manufactured?

This component is proudly manufactured in the U.S.A.

Do I need this if I just bought new Thrashin risers?

Likely no. Newer Thrashin Supply risers already feature pre-drilled 1/4-20 holes on the underside.

What is the finish on this clamp?

The clamp features a durable black finish intended to match the standard Thrashin Supply black aesthetic.

Troubleshooting

Bolt holes do not line up during installation

Ensure you are using genuine Thrashin Supply OG risers, as this clamp is specifically engineered for that geometry.

Accessory screw does not fit the 1/4-20 hole

Verify that your accessory hardware is standard 1/4-20 thread; the clamp is tapped to this specific American standard size.

Pros and Cons

Pros

  • Adds convenient 1/4-20 mounting points for accessories
  • High-quality U.S. manufacturing
  • Seamless aesthetic integration with existing black OG risers
  • Allows for cleaner cable and accessory routing

Cons

  • Mounting hardware is not included in the package
  • Not compatible with all riser brands
  • Redundant for owners of newer Thrashin risers

Setup, Compatibility & Care

Installation involves removing your existing top clamp from your Thrashin Supply OG risers and replacing it with the new unit. Ensure your handlebars are properly centered before final tightening. Because this product requires existing Thrashin OG risers, verify your current riser generation; if yours already has the 1/4-20 holes on the bottom, you do not need this part. For maintenance, keep the clamp clean of road debris and periodically check the torque on your riser bolts to ensure they remain secure under vibration. Use mild soap and water to clean the black finish; avoid harsh abrasive chemicals that may strip the coating.
