SE Rear Frame Loop for BMW K75 K100 K1100 26.80mm with TÜV Approval

SE Rear Frame Loop BMW K75 K100 K1100 26.80mm with TÜV approval

The SE rear frame loop for BMW K-models is the perfect foundation for a clean, technically sophisticated rear conversion for BMW K75, K100, and K1100 motorcycles. This version is designed for frames with an inner tube diameter of approx. 27 mm and is supplied with matching 26.80 mm adapters.

For the conversion, the original rear frame loop is cut off behind the shock absorber mounts and replaced by the Sport-Evolution rear frame loop. The new loop does not need to be welded; instead, it is precisely bolted to the existing BMW main frame using the adapters. This creates a stable and easy-to-install solution for custom roadster, café racer, and custom bike builds.

Detailed installation instructions are included. In addition, the rear frame loop comes with a TÜV parts certificate according to §19.3, providing a solid basis for a TÜV-compliant conversion.

Important: BMW K-models have two different inner tube diameters for the rear frame. These cannot be reliably determined by model or year of manufacture. Therefore, cut off the original rear frame further back first and then determine the actual inner diameter before deciding on the final cutting position.

This ensures you get the right base for a high-quality BMW K75, K100, or K1100 rear conversion in the Sport-Evolution style.
