The Harley Davidson Fat Boy is a line of cruiser-style motorcycles that continues to be offered today. Characteristically, they all feature a low seat height, low riding height and polished metal and chrome exterior trim. The Fat Boy was first introduced in 1990 to serve the heavyweight motorcycle market, distinguished by engines larger than 750 cc.
Engine and Drivetrain Specs
The 1998 Fat Boy features a 1,338 cc, or 81.64-cubic inch engine. It has two cylinders in a "V" layout and features a four-stroke operation. The engine generates 56 peak horsepower of 5,000 rpm and 73 foot-pounds of torque at 2,350 rpm. It is air cooled and features two valves per cylinder with a 3.5-inch bore and 4.25-inch stroke. The drivetrain is belt-based and is paired to a five-speed manual transmission.
Size and Weight
The Fat Boy is a mid-sized cruiser motorcycle that carries a dry, unladen weight of 626.1 lbs. This gives it a power-to-weight ratio of 0.19 horsepower per kilogram. As a cruiser-style bike, it features a traditionally low seat height of 25.7 inches, which is non-adjustable. The low seat height helps contribute to the low-slung look of the motorcycle and appearance of having high handlebars.
Key Features
Like most Harley Davidson cruiser motorcycles, the Fat Boy features excessive bits of chrome trim. Its muffler pipes, handlebars, front shocks, wheels, rear seat trim and engine exterior are all high-polished metal or chrome. It features a single disc brake at the front and a drum brake at the rear. The motorcycle comes with a long seat that can accommodate a passenger at the rear. The gas tank, rear fender and front fender are the only color-matched body pieces on the motorcycle.
