Moto Guzzi Le Mans III from Northern California collection offered for charity
The Moto Guzzi Le Mans III presented here is a rare classic from a private Northern California collection. The motorcycle is believed to have been manufactured in April 1983 and carries VIN ZGUVFAVF4DM100119. The odometer shows 20,000 miles.
The anonymous owner, a longtime associate of Iconic and Bike-urious, will direct all proceeds to a foundation he and his wife operate. The foundation funds research into sustainable agricultural and agroforestry systems worldwide.
Historical significance and mechanical condition
For enthusiasts, the Le Mans III marks a meaningful step in Moto Guzzi’s evolution. The model returned to the U.S. market after Moto Guzzi certified its smaller 844cc engine under emissions regulations. The Mark III introduced roughly 80 technical updates compared with its predecessor.
This example pairs the model’s classic design with a recent series of mechanical refreshes. The work was completed to prepare the bike both for display and for riding use. Transaction data from comparable listings confirms strong collector interest in well-preserved Le Mans III examples.

Historical and mechanical overview
The Le Mans III balances traditional Moto Guzzi character with practical performance. The model’s dry weight is about 453 lb, with factory output near 76 hp at the crank. Published factory figures indicate a top speed close to 132 mph. These specifications place the Mark III among the brand’s more sporting four-stroke twins, combining rideability with touring capability.
Among factory innovations was Guzzi’s Nigusil cylinder lining. The name compresses Nickel, Guzzi and Silicon and denotes a plated bore intended to reduce wear and extend engine life. Technical notes from contemporaneous workshop manuals and specialists highlight the lining’s durability advantage over conventional cast-iron sleeves.
The Le Mans III’s chassis and ergonomics favor a compact footprint and a low centre of gravity. The transverse V-twin layout yields a distinctive shaft-drive feel and a torque delivery suited to both spirited riding and longer cruises. Collectors and mechanics often cite the Mark III’s combination of mechanical simplicity and robust construction as reasons for its enduring appeal.
For historical context and period commentary, authoritative periodicals and specialist texts remain primary references. A detailed treatment of the model appears in Classic Bike, which offers contemporary road-test impressions and production notes that help gauge original performance and specification intent.
VIN, provenance, and title
Confirm the motorcycle’s VIN against factory records and maintenance invoices. Matching numbers strengthen provenance and typically enhance market value. Transaction data shows buyers prefer examples with a documented ownership chain and full service history.
Verify title status before purchase. Check for clear registration, lien releases and any export or import paperwork if the bike has crossed borders. Service receipts, restoration invoices and photographed evidence of original parts provide corroborating detail for a clean provenance.

Service work and condition report
The unit carries VIN ZGUVFAVF4DM100119. It is located in Panorama City, California and is offered by a private party with a clean California title. The seller indicates the bike may be registered as Planned Non-Operation (PNO); that status was not independently verified by the listing service.
Inspection notes supplied by the seller and accompanying documentation describe routine mechanical work and cosmetic conservation. Transaction data shows replacement of consumables such as tires, battery and fluids. Brake pads and hydraulic lines are reported as recently serviced. Photos and invoices identify preserved original components for the engine covers and key trim pieces.
Electrical systems were tested by the seller and reportedly function within normal parameters for a vehicle of this age. Lighting, ignition and charging outputs are shown in the file of service receipts. No major electrical modifications are documented.
Cosmetic condition is documented with high-resolution images. The paint shows period-correct finishing and only light surface wear consistent with controlled use. Minor corrosion is visible on fasteners and peripheral brackets; these areas appear addressed in the restoration receipts.
Structural inspection notes supplied by the seller report frame integrity intact and no evidence of major impact damage. The exhaust system retains its original routing and muffler profile, with refurbishment recorded in the invoices.
In real estate, location is everything; in classic motorcycles, provenance plays the same role. The provided paperwork supports continuity of ownership and part authenticity, increasing market confidence. Brick and mortar always remains tangible; here, photographs and bills form that tangible record.
For prospective buyers, the following verifications are recommended before purchase: confirm PNO or active registration status with the California Department of Motor Vehicles; obtain a pre-purchase inspection by a qualified technician; review original service invoices and parts receipts; and verify the title chain against the documentation provided.
Shipping, registration transfer and any out-of-state taxes or fees can materially affect total acquisition cost. Transaction data shows that resolved title and verified registration typically speed transfers and increase resale value.
The documentation supplied positions the motorcycle as suitable for collectors seeking a well-documented example. Final valuation should reflect confirmed registration status and results of an independent mechanical inspection.
Following the recommendation that final valuation reflect confirmed registration and an independent mechanical inspection, the seller commissioned a comprehensive safety inspection and routine servicing before listing.
The workshop carried out an engine oil change and refreshed the transmission oil and final drive oil. Technicians flushed the hydraulic fluids, cleaned and synchronized the carburetors, and installed a new battery and strap. The rear brake master cylinder was rebuilt and a Dynatek electronic ignition was fitted.
A short test ride of approximately one mile verified the bike runs well on both bench and road tests. Transaction data shows service receipts and photographic evidence accompany the work.
Detailed condition highlights
The list above focuses on mechanical reliability and safety systems. Cosmetic and lighting items were previously documented and are not repeated here. The servicing improves immediate usability and reduces near-term maintenance risk for a new owner.
Buyers should still obtain an independent mechanical inspection to confirm condition and to inform valuation adjustments related to registration status and long-term maintenance expectations.
The seller commissioned an in-shop safety inspection to document mechanical condition and to support final valuation adjustments after registration status was clarified. The inspection report details component status, consumable remaining life and charging system performance.
Mechanical findings include an internal gas tank listed as acceptable and engine oil described as at appropriate level and good quality. Front and rear hydraulic fluids were replaced. The shaft final drive is serviceable. All exterior lighting, the horn and dashboard switches function normally.
Wearable items and electrical readings carry direct implications for near-term maintenance and valuation. Brake pads measure roughly 80% remaining on both axles. Tires are Avon brand with date codes 3114 (front) and 2914 (rear) and show about 90% tread remaining. Battery standing voltage is approximately 12.4V, and charging voltage is 13.9V at 4,000 rpm.
Implications for buyers and valuation adjustments
Transaction data shows consumable lifespan affects short-term ownership costs and near-term ROI. Brake and tire longevity reduce immediate expenditure needs and support a narrower downward valuation adjustment. The recorded battery voltages indicate the charging system is functioning, but standing voltage suggests battery age or discharge that merits confirmation.
For prospective purchasers, recommended follow-ups include an independent road test, a battery load test, and inspection for hidden corrosion around the fuel tank and final drive. Retain service receipts for the recent hydraulic fluid change to substantiate maintenance history.
Brick and mortar always remains tangible, and physical condition drives market perception. Documented mechanical health and high remaining wear on consumables strengthen the asset’s market position and simplify pricing discussions with buyers and valuers.
Le Mans III: upgrades, condition and sale inclusions
Following the inspection that confirmed strong mechanical health and high remaining wear on consumables, the Le Mans III carries several targeted upgrades designed to improve ride quality and longevity while preserving its original character. Fitted items include Works Performance shocks, Rennsport cylinder head guards, aftermarket air filters, braided brake lines and bar-end mirrors. Transaction data shows that such sympathetic upgrades support resale value by reducing near-term maintenance costs.
The service notes record a minor electrical issue: the turn signals are slightly loose but remain operational. The sale includes one original key. Prospective buyers should account for the signal adjustment when estimating immediate service needs.
What comes with the sale and practical notes
Cosmetic blemishes are documented in the photo album attached to the listing. Buyers are advised to review those images carefully and to arrange an in-person inspection in Panorama City. Appointments are required; call ahead to schedule a viewing.
In real estate, location is everything; in specialty-vehicle markets, visibility and provenance matter just as much. The documented upgrades and the inspection report provide a clearer basis for valuation and negotiation. Brick and mortar always remains useful as an analogy: a well-maintained asset commands a premium.
For investors and collectors, the combination of durable upgrades, documented service notes and available imagery simplifies due diligence. Factor the minor cosmetic defects and the turn-signal adjustment into your acquisition budget and expected time to market for resale or use.
