These parts were pulled from a workshop breakdown and are perfect for an active restoration, a 5-speed transmission rebuild, or to keep on hand as a dedicated spares cache. this kit directly fits a huge lineage of famous classic 750cc, 850cc, and 1000cc Italian machines Moto Guzzi Le Mans (Le Mans I, II, III, and Le Mans 1000) ​Moto Guzzi California (Cali II, Cali 3, and early 1100s) ​Moto Guzzi V7 Sport, 850 T3, G5, and 1000 SP ​What is included in this lot: ▪​OEM Clutch Friction Plates: Features the original factory stamping "AP M12F57" (Automotive Products). ​Clutch Pressure Plate & Center Hub: Steel backing pressure plate alongside the heavy, stepped splined clutch center hub/boss. ​Transmission Constant-Mesh Gears: Three individual internal gearbox gears with clean teeth and intact internal splines. ​Gear Selector Dog: One castellated engagement dog sleeve ring. ​Flywheel Starter Ring Gear: Heavy outer ring gear with fine teeth meant for electric starter engagement. ​Clutch Springs: A set of heavy-duty, high-tension clutch compression springs. ​Condition: These are used, vintage mechanical parts. They show authentic wear, grease, and expected surface rust/patina from storage, but they are structurally intact with solid teeth and splines. They have been lightly wiped down but are being sold as-found, as-is—perfect for a classic builder who knows how to clean up and utilize high-quality vintage Italian iron. ​as with any imperfect human, I could be wrong with some of the specifics . [Probably not likely] lol but SERIOUSLY Please study the photos closely to verify fitment for your specific classic Moto Guzzi model year and engine size before purchasing. ​Shipping: Ships fast! Because these components are incredibly dense and heavy, this lot will be securely packed and shipped via USPS Priority Mail Flat Rate to save you money on cross-country shipping costs.
