Honda CB 750 Four Classic Bikes for Sale

Introduction and History of the Honda CB 750 Four

Unveiled at the 1968 Tokyo Motor Show, the Honda CB 750 Four set a new benchmark for motorcycles both in Japan and globally. At a time when most motorcycles relied on two-cylinder or even single-cylinder setups, Honda introduced a 736 cc inline four-cylinder engine with a single overhead camshaft and four carburettors. Paired with a front disc brake and an electric starter as standard, the CB 750 Four outpaced its contemporaries in technology and reliability. Honda’s focus on mass production techniques made advanced technology available to a much wider audience, leading to over 557,000 examples sold by the end of the 1970s, with exports especially booming in Europe and the USA. Its status as a collector’s machine is affirmed by widespread recognition from clubs and historic associations, such as the Automotoclub Storico Italiano.

Model History

The CB 750 Four was produced in several generations. The first series, known as K0–K6 (1968–1976), established the CB 750 as the reference point for performance and reliability. Each generation incorporated minor technical and aesthetic updates. From 1977, the design underwent significant changes with the introduction of models such as the K7, F1 and F2. These later bikes were distinguishable by their revised bodywork and instrumentation. Matching numbers (original engine and frame combination) have become critical for collectors. There was no direct predecessor to the CB 750 Four, but its successors, including the CB 900 and later CB 1100 ranges, all drew on the model’s foundational blueprint.

Special Editions and Collectible Models

Certain editions of the CB 750 Four are especially prized, notably:

• Early K0 models (1969) feature distinctive details like sandcast engine cases and unique colour schemes.
• Limited production models with the original HM300 4-in-4 exhaust.
• F1 and F2 variants, introduced from 1977, with significantly altered styling and specifications, are also noted among collectors.
• US export models often had higher handlebars and other localised changes to comply with market requirements.

Weak Spots and Common Issues

Though renowned for reliability, the following areas merit attention:

• Regular maintenance of oil, filters, battery, brakes, tyres, and spark plugs is essential for longevity.
• Preservation of the original paint, wiring harness, and especially original exhausts is highly valued; replacements or non-standard parts can diminish collectability.
• Watch out for worn carburettors and ignition parts, especially on bikes that have sat for extended periods.
• Matching numbers (frame and engine) are a key point for buyers; check carefully for authenticity.

Engine, Performance, Transmission and Handling

The CB 750 Four’s 736 cc inline-four produces 67 hp, propelling the bike comfortably to around 200 km/h—a remarkable feat for its time. Its five-speed gearbox is precise, and the electric starter offers everyday usability seldom matched in the late ’60s and ’70s. With a front disc brake and rear drum, the stopping power is more than adequate under road conditions of the era. The handling is stable and predictably neutral, making it suitable for both spirited solo riding and comfortable two-up touring. Mechanical reliability and serviceability were principal selling points when new, and remain so today. - K0-K6 (1968–1976): Early models, especially those with original sandcast engine cases, are highly regarded.

• F1/F2 (from 1977): Major cosmetic and technical updates, including new tanks, seats, and revised emission-control systems for certain markets.

Interior, Comfort, Exterior and Design

The CB 750 Four stands out with its teardrop fuel tank, four separate exhaust silencers, and period metallic paintwork. Original colours such as Candy Sapphire Blue Metallic, Candy Antares Red, and Metallic Yellow with black or gold striping are highly prized. US models often had taller handlebars for a more upright riding position. Comfortable seating, practical instrument layout and clear switchgear set new industry benchmarks. Factory accessories included complete toolkits, seat straps and rubber knee pads on the tanks, underscoring Honda’s thorough approach to rider comfort and usability. Many bikes have their original fasteners—a notable detail for collectors.

Other Features

Export versions typically had small adaptations for regional compliance—such as lighting and handlebar differences. The CB 750 Four’s widespread club and association support in Europe ensures robust parts availability and technical knowledge for ongoing restoration or maintenance. The matching numbers of frame and engine enhance provenance and value, especially when factory paint and original components are present.

Summary

The Honda CB 750 Four remains unmatched as a pioneering force in motorcycle history. With its advanced in-line four engine, disc front brake and electric starter, it not only transformed the technical landscape but also the expectations of everyday riders. Boasting a perfect record in both supply and demand within the classic Honda listings on our marketplace, its impact is as strong now as it was upon its launch. For enthusiasts and collectors, original condition and correct details—down to factory paint and matching numbers—are paramount. The CB 750 Four delivers the unique combination of seventies charisma, robust engineering and enduring collectability.
