This is a Baker RSD (right side drive) all-billet CNC-machined tranny case that was used for mock ups. The case and its parts are 20 years old; manufactured back in the hay day of custom motorcycle industry. Just check out the milling work on the inside (see pics.). The case is actually unused because it never had a compete gear set, but it does show some light pitting throughout the bottom part of the case. Several bolts for the top cover are missing, as well as one for the clutch cover. Please review the photos carefully for what's exactly included (more photos available upon request).
Please feel free to ask any questions before committing to purchase.
