Japanese motorcycle fans have reason to celebrate this fall — three rare Yamaha classics are rolling to auction on November 5th as part of the Frank Sega Collection, presented by Premier Assets LLC on Proxibid. The online event begins at 11:05 a.m., featuring everything from original parts to low-mileage collector bikes, and these Yamahas are among the standouts.
1978 Yamaha SX-650
This 1978 Yamaha SX-650 offers vintage twin-cylinder charm with a double overhead cam engine and just 952 miles showing on the title. The engine cranks, and it includes a key, chain drive, and an Ohio title marked “Non Actual” due to an odometer discrepancy. Finished in classic Yamaha style, this SX-650 represents a key model from the late 1970s when Japanese engineering dominated the global market. VIN: 2F0112779, located in Chardon, Ohio.
1976 Yamaha RD-400
Two-stroke fans will love the 1976 Yamaha RD-400, known for its light weight and razor-sharp handling. Powered by an air-cooled 399cc straight twin, this model remains a favorite among collectors. With just 6,579 miles, this example cranks, includes a key, and carries a current Ohio title. VIN: 1A1015549, Engine No: 1A1-015549.
1976 Yamaha RD-400 CR
A rarer variant, the RD-400 CR is another air-cooled two-stroke twin, built for pure performance. This example is listed as TMU (True Mileage Unknown), with no odometer or speedometer, but the engine cranks and it includes a key and current Ohio title. VIN: 1A1016480, Engine No: 1A1-016480.
Each of these bikes embodies a different era of Yamaha’s engineering brilliance — from the torquey twin of the SX-650 to the fast-revving RD-400s that made their mark on tracks and backroads alike.
Which of these Yamahas would you bring home — the street twin or the two-stroke legend?
