Yamaha AS1 Parts - Yamaha AS2 Parts

Back in 1960’ s 125cc engine motorcycles were used as utility vehicles, but as technology advanced, they became more and more popular as sport and touring bikes. If you were a teenager back in those days, the Yamaha YAS1 could have easily been a motorcycle of your dreams.


Yamaha YAS1

Introduced in 1967 in Japan, Yamaha AS1 defied all motorcycle logic with its miniaturisation and simplicity. Yamaha 125 AS1 was lightweight and relatively cheap with many parts identical to the Yamaha FS1 moped. The basic tubular frame carried 125cc two stroke twin air cooled engine. Both YAS1 & YAS2 had cast iron twin cylinders, single shoe drum brakes at front and rear, chain transmission, enclosed suspension at front and rear and chromed tank panels. The sports bike look was finished off with twin chrome exhausts. It came in two colours only Red or Blue.

1970 Yamaha AS2 / YAS2 was an aesthetic evolution of YAS1 with different tachometer, double cam and larger fuel tank

1971 Yamaha AS3 / YAS3 received a major upgrade. It was larger, heavier and much chunkier version of the old YAS1. The engine was housed in a new frame, it got new set of front forks, aluminium cylinder and other new features.

The popularity of Yamaha AS3 125, especially in France and continental Europe, was so immense,  that Yamaha made special edition bike, the Yamaha YAS3 Europa with wide large capacity 11.5l fuel tank and even optional full race kits for all YAS models. With the reed intake valves introduced in 1973 the era of YAS Pocket Rocket ended followed by the next generation Yamaha RD125 (Yamaha RD AS3).
