BIKES YOU’VE NEVER SEEN BEFORE: 1966 SUZUKI RA125 ROTARY VALVE
This is a 1966 Suzuki factory 125cc motocross bike that was raced in 1967 and 1968 before going into storage. The stripped-down 125cc motocross racer didn’t have an official name at Suzuki, but was called an RA66, RA125 and modified S10.
The 125cc two-stroke, rotary, single was built on a modified 1965 S10 bottom end. It had a 24mm Mikuni VM24 carburetor, and a four-speed transmission. It was unrestored, but still ran after 56 years of neglect. It sold at the 2020 Mecums Motorycle Auction for $27,500.
