🔍 CONDITION REPORT

We sell a mix of used, new old stock (NOS), and brand‑new motorcycle parts.

Please read the condition noted in the listing, and use the details below as a guide:

We verify fitment as accurately as possible, but please confirm compatibility with your bike before purchasing. Condition is subjective — if you’re unsure, feel free to ask questions.

🛠️ Used Parts

These parts have lived a real road life. Expect normal wear such as scratches, scuffs, small chips, or minor cracks. Some marks may not show clearly in photos due to lighting. A quick wipe‑down may be needed on arrival.
