INDIANΠMOTORCYCLE POWERPLUS٠100 V-TWIN ENGINE
The Power behind the Legendary Indian ChiefΠMotorcycle
True to the classic styling and performance heritage that makes Indian one of the most admired brands in American history, the powerful 100 cubic-inch (1638cc) 45-degree, Powerplus٠100 V-twin engine recreates the unique look and robust feel that captured the affection of motorcycle enthusiasts around the world.
For 2003, the flagship Indian ChiefΠline comes with the Powerplus engine, the largest displacement engine designed and built by an American OEM motorcycle company.
The signature feature of the new Indian motor is its serrated, billet-aluminum rocker boxes and stout, round cylinders that are impossible to ignore.
Distinctive and unique to Indian, the serrated appearance of the polished rocker boxes and the black, rounded cylinders pay tribute to Indian's past. This combination gives the Powerplus 100 engine a strong, unique profile, while the rounded cylinders increase the area of the cooling fins for improved air circulation and engine cooling.
The engine is fed by a 42mm Mikuni "flat-slide" carburetor that is mounted on the left side of the engine, which is unique to early Indian motorcycles. This carburetion package delivers smooth throttle response throughout the entire RPM range.
Although this engine configuration is carbureted, the Powerplus 100 platform is designed to accept fuel injection with minor modifications. To ensure optimum lubrication and scavenging, the motor features a gerotor oil pump system. The transmission is a proprietary wet-clutch, five-speed configuration with a final belt drive. Although the configuration is standard in design, the wet-clutch itself is strengthened for added durability. A two-into-one exhaust header completes this performance package.
The introduction of the Powerplus٠100 engine completes the return of Indian Motorcycle Corporation as an American motorcycle OEM.
