Yamaha RD 350 classic bikes for sale

History of the Yamaha RD 350

Yamaha introduced the RD 350 in 1973 as the spiritual successor to the R5 350, building on its base but adding technical improvements like reed-valve induction. This twin-cylinder, air-cooled two-stroke broke new ground in lightweight sport bike performance, quickly gaining a reputation during its brief production until 1975. The RD 350 adopted design elements and technology shared with Yamaha's TR racing bikes—particularly visible in components like the fuel tank—showcasing its competition pedigree. The model thrived on both public roads and in motorsport, where it was popular in hill climbs and classic racing events.

Model History

The RD 350 evolved directly from the Yamaha R5 350, retaining the 350 cc twin-cylinder layout but adding reed-valve induction to improve throttle response and efficiency. Early production models came with a 5-speed gearbox, while later variants saw the introduction of a 6-speed transmission, especially on the UK market. Official production of the RD 350 concluded in 1975, with later models like the RD 400 and variations for different global markets carrying the torch for Yamaha's distinctive two-stroke line.

Highlights of the RD 350

The Yamaha RD 350 is defined by its light frame, quick-revving 350 cc parallel-twin, and air-cooled engine setup. It produced 39 bhp at 7,500 rpm and was fitted with a reed-valve intake—advanced for its time. Factory features included Kayaba shock absorbers, Dunlop racing compound tyres, and original TR-series race spec equipment like identical tanks. Racing ignition systems, custom swingarms, and carbon reed-valves reflect the model's adaptability to competitive upgrades. Colour options such as "Ruby Red" with pinstripe gave it distinctive road presence.

Technical Data

Special Editions and Collectible Models

No official factory special editions were produced, but many RD 350s are fitted with period-correct racing parts, hill-climb adaptations, or aftermarket upgrades such as carbon reed-valves and performance exhausts. Some custom builds feature reinforced swingarms and reconditioned forks for enhanced endurance racing performance.

Weak Spots and Common Issues

Detailed information on recurring technical flaws is not available in the provided data. However, buyers should consider the age-related wear typical for two-stroke bikes, potential modifications from motorsport use, and the condition of key components such as the gearbox, ignition, and chassis, especially if fitted with racing or aftermarket parts.

Engine and Performance, Transmission and Handling

The RD 350 is known for its energetic powerband and light chassis. Acceleration and response are strong, largely thanks to the reed-valve two-stroke engine. With the shift from a 5- to a 6-speed gearbox, gear spacing became much more optimal for both road and competitive use. Handling is agile, facilitated by the steel frame and Kayaba suspension, while braking on early models remains period-correct with a drum setup. Numerous bikes have upgraded forks and swingarms, reflecting common racing adaptation. Many enthusiasts appreciate later 6-speed versions and extensively rebuilt racing or hill-climb configurations, especially those running FENSA racing ignition, Dunlop KR tyres, or custom exhausts.

Interior, Comfort, Exterior and Design

While comfort was not the main priority, the RD 350 offers sport-oriented ergonomics with a slender tank, allowing riders to tuck in during spirited rides. Design cues such as the original TR-spec fuel tank, Kayaba suspension, and unique paint schemes (notably 'Ruby Red' with pinstripe) underscore its sporting roots. Special features include optional racing parts like reinforced swingarms or aftermarket exhausts—accessories that reflect the model’s flexibility both in style and motorsport use.

Other Relevant Information

The RD 350 is a frequent sight at historical motorsport meetings and classic trackdays, with a strong community and aftermarket support. Period modifications and racing builds can add significant variation from bike to bike. Documentation and provenance, especially regarding any genuine Yamaha racing components, play a significant role in determining collectibility and value.
