1972 Yamaha DS-7

The little Yamaha YDS7’s were little gems in their day, the building blocks for the RD250’s and the later RD250LC “Elsie” which are famous for launching a thousand racing careers, in the one make series. With 24hp being served up at 7500rpm they were as near to racing bikes as you could get and they were in fact raced quite successfully, this little air cooled 250cc twin was a 5 speed machine with drum brakes at the back and the front. The engine numbers were the same as the frame numbers so it is easy to see if the engine has been changed.
