Silver plus is a two-seater, step-through motorcycle that was introduced by Royal Enfield Motors in India in the 1980s. It was one of the first geared step-through motorcycles in India. It was launched along with Explorer, another mini bike, a two seater that featured the same engine. While Silver Plus featured a hand operated cable link gear shifts, Explorer used a foot-operated gear shift.
Engine, transmission and performance
The Silver Plus was powered by a two-stroke, 65 cc air-cooled, carburetor engine, manufactured with technical assistance from Zundapp. The transmission supported two gears and the gears are operated by hand, much like the Italian scooters. Royal Enfield subsequently upgraded the bike to a three-speed gearbox.
