The Norton Commander

The Commander was not originally planned for general market release, being developed strictly as a police motorcycle. The limited-edition Classic, released the year before, generated demand for a follow-up model. But Norton had nothing on the drawing board, so the company quickly stripped the police specific features from the P52 and introduced the P53 Commander as a sport touring model for the general market. Both versions of the Commander were produced for four model years, from 1989 through 1992.

Norton Commander Specs

The P53 Commander remained virtually unchanged during its four-year run. It was powered by a liquid-cooled, 588-cc, dual-disc Wankel rotary engine. The rotary engine generated 85 horsepower at 9,000 rpm and had a top speed of 119 mph. The Commander had a five-speed transmission with a chain final drive. The bike had a street weight of 577 pounds and held 6 gallons of fuel. No motorcycles with Wankel engines have been produced for sale to the general public for road use since 1992.
