Rear Frame Loop - 1 Inch

Built from .069 wall DOM steel tubing and manufactured in-house at Thirteen Motorcycles, these 1" rear frame loops are designed to give your café racer a clean, timeless finish. Each loop measures 9 3/4" wide from end to end and is left with extra material on both sides so you can trim and fit it perfectly to your seat and frame for a true custom-built look. Works on most bikes above 500cc. 

Designed with a straight, flat profile, these loops keep the stance classic and purposeful while giving you the flexibility to shape the final look of your build. Whether you’re building a stripped-down tracker or a traditional café racer, they provide a solid foundation for a clean rear frame section.

Installation is intended for builders comfortable with fabrication and welding. After cutting the rear section of your frame, it is highly recommended to sleeve or “slug” the frame using solid steel bar stock before welding the loop into place for added strength and alignment. Depending on your specific frame dimensions, you may need to slightly open or close the width of the loop during fitment. This can easily be done with a vise and a little leverage to dial everything in before final welding.

Once mocked into position, weld everything up, smooth the joints, and finish it however you’d like. Since every vintage frame is slightly different, minor adjustments may be needed during installation. With a little patience and fabrication work, these loops can be tailored to fit nearly any build perfectly.
