Technical Overview

1959 Simplex Automatic Technical Analysis & Specification Breakdown

Built around Simplex's allround motorcycle platform, the 1959 Simplex Automatic relies on a 130 cc (7.9 cu in) single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 4 HP (2.9 kW) at 5,000 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 30.8 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

The 9.46-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
