1971 Honda SL 175 K0 – Concours Restoration / Museum-Quality Collectible

The Story Behind the Machine

The Honda SL175 was a motorcycle born from a specific moment in time—the early 1970s, when the "street scrambler" look was taking the motorcycling world by storm. Produced by Honda from 1970 through 1972, the SL series was designed as an intentional enduro-style machine with raised fenders, an upswept exhaust system, and universal tires—a dual-purpose motorcycle equally at home on backroads and trails.

The SL175K0, the first-year model, was powered by a 174cc OHC parallel twin engine with a 5-speed transmission and manual clutch. What made these bikes special was their remarkable balance: dimensions and weight barely more than a comparable 125cc machine, but with significantly more power and speed. The 175s were immensely popular, bridging the gap between lightweight trail bikes and serious off-road machinery.

What makes this particular SL175K0 exceptionally rare is its origin story. These motorcycles were primarily destined for the Asian, African, and American markets—very few were ever imported into Europe. In fact, the SL175 was never officially imported into the UK. To find one in Europe at all is uncommon; to find one in this condition is nothing short of extraordinary.

The Bike 

This 1971 Honda SL175 K0 presents in concours restoration condition—a level of quality that is rarely seen outside of museum displays or professional collections.

The restoration has been executed with fanatical attention to originality. Every single component has been replaced with genuine Honda parts—right down to the fasteners—demonstrating a commitment to authenticity that is almost impossible to find today. For components no longer available from Honda, high-quality reproductions have been sourced to maintain the factory-correct appearance.

Frame & Bodywork: The frame has been professionally sandblasted and finished in durable Epoxy paint, ensuring decades of protection against corrosion. All bodywork elements have been painted in the correct Candy Orange—the iconic color that defined the SL175K0—with the tank design precisely matching the 1971 model year specifications.

Mechanical Status: The engine has been fully rebuilt and is now ready for running-in (break-in period). Both pistons and rings are NEW and have been machined to the 2nd oversize. The clutch, ignition system, brakes, rims, tires, cables, chain—everything is NEW. This motorcycle is not a project; it is a turn-key machine that has been restored to better-than-new mechanical condition.

The Engine: The engine is a 174cc OHC parallel twin with a 5-speed transmission. All seals, gaskets, and papers have been replaced during the restoration.

Odometer: Exceptionally low kilometers.

Rarity Factor: The SL175K0 was sold only in 1970-1971. With very few examples ever reaching European shores, this bike represents a genuine collecting opportunity that seldom presents itself.

Why this bike is the opportunity:

This is not an entry-level project bike; this is a finished, award-ready collectible offered at a fraction of the restoration cost. The buyer acquires a museum-quality motorcycle without the wait, the hassle, or the expense of sourcing rare parts and skilled craftsmen.

Known Issues

• Mileage is low: The bike has seen minimal use since restoration

• Originality note: Some parts no longer available from Honda have been replaced with high-quality reproductions

• Collection vehicle registration: Registered as a "véhicule de collection" (historic vehicle) in France

• Age-related sale: The vendor is selling due to advancing age and reduced riding activity—this bike has been part of a carefully maintained collection

This is not a project bike. There are no mechanical issues, no missing parts, no rust, no damage. This is a completed concours restoration ready for display or selective riding.

Why Bid?

This 1971 Honda SL175 K0 represents a once-in-a-decade opportunity to acquire a concours-restored example of one of Honda's rarest dual-purpose motorcycles.

Consider the math: A proper restoration of a motorcycle like this—with NOS Honda parts (even the fasteners!), professional Epoxy frame painting, correct Candy Orange bodywork, and a full mechanical rebuild—would cost far more than this bike's reserve. The vendor has done the hard work, spent the money, and invested the time. You simply write the check and take delivery of a finished masterpiece.

The SL175K0 was produced for only a short time and was never officially imported to Europe. Finding one in any condition is difficult. Finding one in this condition—with documented restoration, original tool kit, duplicate keys, and full paperwork—is extraordinary.

Whether you are a serious Honda collector completing a full SL series collection, a vintage motorcycle enthusiast seeking a pristine example of a rare model, or an investor looking for a blue-chip classic that will only appreciate in value, this SL175K0 checks every box.

Buy a finished concours restoration for less than the cost of building one yourself.
