Yamaha Rd 350
The Yamaha RD350 was introduced in 1973 as the successor to the DS7/R3 series, featuring a revolutionary reed-valve induction two-stroke parallel twin engine that delivered exceptional power for its displacement. It quickly earned a reputation as one of the finest handling and most exciting lightweight motorcycles of the 1970s, dominating club racing and becoming a cult classic among enthusiasts. Production continued through 1975 for most markets, though the RD350B variant followed in 1975-1976, and the model left a lasting legacy that influenced Yamaha's two-stroke lineup for decades.

What Buyers Should Know
Powervalve-Free Two-Stroke
The RD350 uses a simple reed valve induction system without powervalves, making it mechanically straightforward to maintain. However, the two-stroke engine requires regular top-end rebuilds every 5,000–8,000 miles to stay healthy.
Watch the Expansion Chambers
The tuned exhaust expansion chambers are critical to performance and are expensive to replace if rusted or dented. Always inspect them closely — dents or holes cause noticeable power loss and are a strong bargaining point.
Strong Collector Resale Value
Clean, original RD350s have steadily appreciated in value, with well-maintained examples selling for $4,000–$8,000+. Its legendary status as a 'pocket rocketship' of the 1970s keeps demand high among enthusiasts.
