Indian Motorcycles Powerplus 1916
The Powerplus was introduced by Indian in 1916; comprising a new 61ci (990cc) flat head (side-valve) V twin engine.
The transmission consisted of a 3-speed, hand-change gear change and foot operated clutch with all chain drive. An immensely influential design, the Powerplus confirmed Indian’s commitment to side-valve engines, encouraging rivals Harley-Davidson to follow suit. The model was listed until 1924 but by then was playing second fiddle to the newer Chief.
Purchased from the US, this bike was restored in 2005 using an engine dating from 1919. The frame, tanks, forks and mudguard tip are original Indian components, while the rest of the cycle parts are all replicas.
Refurbishment included a new crank pin, main shafts and bearings, cylinders relined, valve seats reclaimed, new JP pistons, new G&S valves, guides and sprigs, new gear box bearings and pinions, reconditioned carburettor and magneto, new wheel rims, spokes and tyres, with new paint and nickel plating.
