Gilera B300 Classic Motorbikes: Prices & Market Values

The market value of Gilera B300 motorcycles is primarily determined by technical condition, originality, and mileage, as well as rarity, history, and documentation. A well-maintained, largely original vehicle with low, verifiable mileage and a complete history including expert reports and documentation generally achieves significantly higher prices than a comparable vehicle with deferred maintenance, extensive modifications, or an unclear provenance.

Gilera B300: Market Prices & Value Trends

Based on Classic Trader marketplace sales data from March 2021 to July 2025, the Gilera B300 market shows a clear softening after a stronger 2021–2022 period. Earlier pricing for mid-1950s bikes (notably 1955 and 1958, typically quoted at 15–19 hp) regularly sat in the £5,200–£8,700 bracket, reflecting collector demand for earlier Italian classics and higher-quality restorations. Since late 2022, however, many recorded prices cluster around £4,200–£5,250, and by mid-2024 to mid-2025 the lowest observed figures dip to roughly £2,200–£2,500 for certain examples, suggesting more price sensitivity or more “project” condition bikes coming to market. Excluding those lower-end outliers, a realistic current market range is around £4,000–£5,500, with exceptional early bikes still capable of pushing higher when condition and provenance justify it. Overall, supply appears steady and prices broadly stabilising at a more accessible level, especially in Italy where the majority of data points sit.

History of the Gilera B300

Gilera’s B300 emerged from a lineage of motorcycles synonymous with Italian craft and innovation. Designed in the post-war era when practical, reliable, and stylish transport was in demand, the B300 filled a niche for mid-size bikes that combined daily usability with distinctive Italian flair. Gilera, a brand long associated with both road and racing bikes, employed its technical know-how and manufacturing acumen to create a model with broad appeal, especially in European markets during the 1950s and 1960s.

Model history

The Gilera B300 built upon the brand's earlier single and twin-cylinder machines, offering an alternative to both lightweight entry-level bikes and larger, more complex motorcycles. While it did not have a direct predecessor within Gilera’s catalogue, it was positioned to complement the sportier and larger-displacement models already present. The B300 served as a practical choice for many Italian and European riders before gradually being phased out in favour of more modern, higher-displacement designs as the motorcycle market evolved in the late 1960s.

Unique Highlights and Market Data

The B300 stands apart with its characteristic Italian mechanical layout and reliable performance. Appreciated for period touches—such as detailed tank badging and purposeful seating—the B300 is a representative of Gilera’s mid-century focus on quality and style.

Technical data

Special Editions and Collectible Models

Based on available data, there are no widely recognised special or limited editions of the Gilera B300. Collectability tends to centre on well-preserved standard models with original features intact.

Weak spots and maintenance

No manufacturer-specific weak spots are referenced in the current data set. When purchasing a Gilera B300, the usual classic bike maintenance applies: inspect the condition of the engine, the integrity of the frame, and the state of electrical components. Given the age, particular attention should be paid to the condition of original parts and the quality of any previous restorations.

Engine, Driving Characteristics and Handling

The B300 offers a balanced and approachable riding experience suitable for city and touring use. With its moderate displacement and responsive throttle, the B300 delivers performance closely matched to period expectations—enough to satisfy everyday rhythm while remaining accessible for less experienced riders. Handling is classic mid-century Italian, with an emphasis on stable steering and comfortable suspension. Within the Gilera catalogue, the B300 commands the entirety of both supply and demand in classic listings, effectively making it the most recognised and sought-after Gilera motorcycle in the collector's arena.

Design, Comfort and Accessories

The Gilera B300’s visual appeal stems from its harmonious proportions, traditional Italian tank design, and functional riding position. Notable design elements include the chromed tank panels, distinctive badging, and a chassis constructed with an emphasis on reliability and serviceability. Optional accessories typical for the era include leather saddle bags and period-correct rear luggage racks, underscoring the bike’s utility and adaptability to touring.

Further details and facts

The B300 is frequently praised for its ease of maintenance and the availability of replacement parts, particularly in European markets. Community support and documentation on restoration techniques are well-established due to its concentrated presence among classic Gilera enthusiasts.

Summary

The Gilera B300 embodies the values of mid-century Italian motorcycle engineering, combining style with robust functionality. Its exclusive representation of the Gilera marque among classic listings makes it a definitive reference for collectors seeking authenticity and mechanical purity. This model continues to stand out in the classic motorcycle landscape thanks to its distinctive design and solid reputation for reliability.
