Description
Indian PowerPlus 1921 “Big Valve” 998 cc side valve V- twin combination engine & frame# 73S524
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.
Power developed is a healthy 18 BHP.
This combination with Swedish reg. number is a super quality restoration.
Note the AGA acetylene cylinder, a typical Swedish detail.
The machine comes complete with Corbin speedometer.
