In 1925 both Harley Davidson and Indian decided to enter the small capacity market with their 21 cu machines (350cc). Both had sidevalve engines and the Indian model was called the Prince. For 1925 it had the wedge shape petrol tank but by 1926 was upgraded to the more popular big brother tear drop style tank. Advertised with a top speed of 60 mph my friend Injun Dave said that they were not a great performer and top speed was more like 40 mph (he would know as he used to own one). Still a very pretty little motorcycle.
