Twisted Choppers Radius Rear Custom Fender

Build your custom motorcycle from the ground up with a blank canvas that handles everything your imagination demands. The Twisted Choppers Radius Rear Fender delivers the clean, classic arc profile that choppers and bobbers have been built around for decades, letting you shape the final look entirely in your shop.

Key Features

  • Hand-spun from 13-gauge U.S. steel, significantly thicker and heavier than standard off-the-shelf fenders
  • Classic radius arc profile, the clean, proven blank canvas for chopper and bobber builds
  • Standard 1.75-inch sidewall depth, ready for flat struts, welded bungs, or custom mounting hardware
  • Structurally strong enough to support a passenger when properly mounted with internal struts
  • Ships raw for full control over surface prep, body filler, and paint or powder coat finish

  • Supplied in raw, uncoated spun steel finish; visible spinning lines are normal and expected on hand-spun parts
  • Apply high-build surfacer or body filler to smooth the surface before painting or powder coating
  • Optimized for standard 18-inch motorcycle wheels; select fender width by rear tire size

Can the rear fender be ordered as a high cut fender? Steven Fraser asked on December 17, 2024

All of our rear fenders start from the same blank but have different cuts in the side. A Hi-Cut is the same as this Radius fender but with a higher cut in the side.

What is the diameter of tire this will fit? I have a 21" x 180mm wheel will this fit over the tire? Ron asked on July 25, 2024

The maximum tire height these fenders will accept is 26.5". The width is based on the size you choose but we recommend the 8.5" for a 180mm wide tire.

Will this fender fit a 2001 wide glide with a 150/70R18? Vaporz asked on June 20, 2024

These can work but we do not make an application specific fender for this. You will need to take measurements and see if it's going to work for the style you want.
