Vehicle Information
Yamaha RD250 Motorcycle - Street (1973-1975)
The Yamaha RD250, produced from 1973 to 1975, was a celebrated two-stroke motorcycle renowned for its performance and agility. This air-cooled, parallel-twin engine, featuring reed-valve induction, delivered 30 horsepower from its 247 cc displacement, paired with a 6-speed transmission. The RD series marked a significant evolution from earlier models, introducing advancements like the "Torque Induction" system for improved low-RPM performance and horizontally split crankcases for a cleaner design. While the core engine specifications remained consistent across these years, the RD250 saw some notable updates. Early 1973 models initially had the 6th gear blanked off, though it could be enabled. A more significant change occurred in 1975, when the RD250 generally received a front disc brake as standard, replacing the earlier drum brake on many models. The 1975 RD250B also featured revisions to its cylinder heads and gear ratios, indicating minor but impactful refinements. FAQ:
