Honda CB 900 F Bol d'Or classic motorcycle for sale

History of the Honda CB 900 F Bol d'Or

Honda presented the CB 900 F Bol d'Or at the end of the 1970s to tackle the European market, especially in response to increasing demand for fast, reliable bikes with motorsport DNA. The 'Bol d'Or' in its name references the famous 24-hour endurance race in France, highlighting the bike's inspiration from racing technology. Structurally, the CB 900 F was recognised for its independent frame concept, a reinforced rear frame, and a tough swingarm. For its time, it delivered a synthesis of sportiness and everyday usability over long distances. Many details, from the engine construction to the optional upgrades, underline Honda's consistent pursuit of performance and reliability during the late 1970s and early 1980s.

Model history

The Honda CB 900 F Bol d'Or sits in the model lineage between the CB 750 F and later muscle bikes like the CB 1100 F. Its main competitor and indirect successor in the Honda lineup was the CB 1100 series, which adopted many technical features and design cues. The 'F2' variant established additional advancements in cockpit and bodywork, responding to the growing expectations of sport-touring riders. CB 900 F's robust platform paved the way for many post-production modifications and has since become a basis for a variety of conversions, including cafe racers and touring upgrades.

Highlights and characteristics

The CB 900 F Bol d'Or is specifically appreciated for its single-piece chassis and the possibility to upgrade nearly every component. Swingarms can be replaced with box-section units, shocks swapped for modern brands such as Koni, Wilbers or Öhlins, and braking systems often receive substantial upgrades. Customisation to sportier riding postures is common, including clip-on handlebars and rear-sets, making the 'Bolle' one of the most versatile bases for classic rebuilds. In addition, there's an abundance of options for the exhaust (e.g., 4-into-1 systems from Sebring or Schüle), electronic upgrades (like Motogadget units), and even complete conversions into cafe racers – frequently executed in TÜV-compliant form in the German-speaking scene.

Technical Data

Special editions and notable variants

Within the CB 900 F Bol d'Or family, the F2 variant is notable for its more advanced cockpit and extended bodywork. Special attention is paid within the community to conversion projects, including full cafe racer transformations, with modifications often documented with valuation reports (e.g., DEKRA). While true limited-edition factory models are rare, numerous custom one-offs exist due to the popularity of complete builds and upgrades in this platform.

Weak spots and maintenance advice

The CB 900 F Bol d'Or requires attention to certain technical areas over time: engine overhauls (including timing chains, chain guides and primary shaft dampers) should be planned as wear becomes apparent. Carburettors are a known area for cleaning, synchronisation, and replacement of seals. Upgrades to electrical systems (including partial re-wiring or digital upgrades) can be beneficial for reliability. Pay attention to the condition of paint and coating, especially on older powder-coats or custom finishes. Frame and swingarm modifications or conversions (like rear subframe reshaping) should always be checked for proper documentation and registration. Many upgraded or replaced components (braking, suspension, electronics) require TÜV certification if the vehicle is used on public roads in Germany. Keep an eye on classic wear-and-tear spots, such as seat covers, tank coatings, and the functionality of older instrumentation.

Engine, transmission and handling

With its air-cooled engine, the CB 900 F Bol d'Or delivers distinctive four-cylinder performance, regularly enhanced by period-specific or modern upgrades. Many owners choose to refresh or fully rebuild engines to suit custom needs or to restore performance. Gearboxes can require routine adjustment or overhaul over time, and mild upgrades (for example, clutch or gear selector) are common in project bikes. Suspension and steering components see frequent customisation, from adjustable dampers to bespoke triple clamps and bars. Modern tyres and upgraded brake systems (such as steel flex lines and new calipers) give the CB 900 F a substantial handling improvement over factory setup. The riding experience can thus be tailored from touring comfort to aggressive cafe racer style, all depending on the individual bike's configuration. Notable choices for project or restoration enthusiasts include: CB 900 F2 Bol d'Or with updated cockpit and bodywork, conversions to box-section swingarms or upside-down front forks, and bikes modified to full cafe racer spec (including clip-ons, seat cowls and digital electronics).

Design, bodywork and equipment

The design language of the CB 900 F Bol d'Or is distinctly late 1970s sport-touring, with broad tanks, clear visual cues from endurance racing, and a functional but recognisable silhouette. There is a high prevalence of modified finishes, including 2K clear coats or heat-resistant paints for engines, sandblasted or powder-coated frames and swingarms, and individually painted or stickered fairings – sometimes in classic multi-tone schemes or referencing later CB 1100 F design motifs. Accessory ranges include custom cockpits (digital, with LED lighting), bespoke handlebars (clip-ons, bar-end indicators), aftermarket exhausts (4-1 design), and optional special seating in synthetic leather or Italian design. Some bikes have seat cowls and rear frame modifications fully homologated for road use, typical for German and Central European builds.

Other relevant info

Conversions are sometimes accompanied by formal value assessments (e.g., DEKRA) and are frequently executed to be fully TÜV-compliant in Germany, reflecting the strong local focus on technical documentation and road legality for custom builds. Café racer conversions and custom seat and rear frame work are particularly widespread. Innovative solutions such as keyless ignition (RFID), relocated batteries, and upgraded Motogadget control units underline the technical adaptability of this motorcycle.
