1972 Yamaha DS7 Cafe Racer History - Yamaha YDS7 Parts
Inspired by the race bikes of the late 1960's, the Yamaha
DS7 250 (or also called YDS7) was lighter and slimmer than its
predecessors. It was yet another step towards the famous Yamaha RD series with reed valve induction system. The mighty Yamaha YDS7 was introduced to the market in 1972 and soon
became popular amongst racing bikes enthusiasts.
Yamaha DS7 Specifications
Yamaha DS7 had air cooled 250cc twin two stroke engine with piston port
controlled fuel injection. The crankcase housed 5-speed gears with a chain drive transmission, the front wheel as well as rear wheel were fitted with expandable drum brakes. It also had only manual kick start. There was no need to pre-mix
fuel and oil, the oil tank and the fuel tank were kept separate with sight glass into oil tank
providing rider access to check the levels.

signifying the year it was made. 1972 Yamaha DS7 250 was
produced in Candy Orange colour with Serial No: DS7-100101-125298.
