1626 YD - Indian Powerplus 998 cc side valve V- twin – 1917

The Indian PowerPlus engine was a design of Charles Gustafson, who had already earned fame as an engine designer at the Reading Standard company before he was approached by the Indian management.
His task was to design a powerful, robust, reliable and production friendly engine to replace the old F-head V-twin design of Oscar Hedstrom. The resulting 61” side valve PowerPlus introduced in 1916 was an immediate success and this model is still one of the most coveted American vintage motorcycles. This machine is a 1917 model which developed a healthy 18 BHP.
