This 1970 Yamaha RT1 was purchased by the seller 9 years ago in Northern California and is powered by a 360cc two-stroke single paired with a 5-speed transmission. Work performed under current ownership reportedly included a rebuild of the oil injection pump and replacement of the engine seals, fork seals, wheel bearings, and swing arm bearings. More recent work is said to have consisted of a compression test, a new rear shock, crankcase oil, and a new air filter. This RT1 is offered with the factory tool roll, service manual, and a clean California title in the seller’s name.

The fuel tank and oil tank are finished in black with yellow striping and the fenders in silver. The seller notes the rear fender, frame, and forks have been repainted due to sun fading, and the wheel bearings, swing arm bearings, fork seals, and battery have been replaced.

The 360cc two-stroke single features an auto-lube oiling system and was factory rated at 32 horsepower. A 5-speed transmission transfers power to the rear wheel via chain drive. The seller reportedly replaced the engine seals and rebuilt the oil injection pump, and prior to the sale a compression test was performed, the lubricants replaced, and a new air filter installed.
