This is a bin of miscellaneous parts similar to a brake stay, caliper mount, rear brake bracket, and brake arm.
These are self serve items, you are welcome to come in any time we are open and sort through them. The prices are low because you have to do the searching (not us). These parts are not cataloged, and some are in need of minor repairs. We STRONGLY recommend you bring the old part you are looking to replace to help you find a match.
Although we cannot say for sure whether any particular part is in there or not, we can tell you if it is likely based on what we have taken apart over the years and what we haven't (not based on specific knowledge of what is left in the bins). The parts in the bins are a compilation of the several thousand motorcycles we have taken apart over the last 20+ years.
