Royal Riley Motorbike 3hp (1903-04)

In 1903 the Riley Motorbike was revised with a stiffer frame and a new range of Riley built engines. The 3hp was the middle of the range, and whilst it retained pedals to allow the rider to assist the engine on hills, it is likely that they were rarely required. After just a year, all of the motorbikes were dropped as Riley concentrated on 3-wheelers.
