Indian Motorcycle has unveiled its exclusive Signature Series to celebrate the brand’s 125th anniversary. The limited-production collection is based on four premium models: the Challenger, Chieftain Powerplus, Pursuit, and Roadmaster Powerplus.

The special-edition motorcycles focus on handcrafted detailing, unique paint finishes, and premium touring equipment rather than mechanical changes. Indian says the paintwork uses a multi-layer process designed to create greater depth, contrast, and a richer finish.

Challenger and Chieftain Powerplus
The Indian Challenger Signature Series gets an Abyss Metallic finish with a black base and red graphics. It also features a blacked-out engine and overall dark finish, along with remote-locking saddlebags, cruise control, an electronically adjustable windshield, and an upgraded 400W PowerBand audio system.

The Chieftain Powerplus Signature Series follows a similar blacked-out theme but uses green graphics. Both motorcycles are powered by the same 112ci liquid-cooled PowerPlus V-twin, producing 126hp and 180Nm, with power sent through a six-speed gearbox.

Pursuit and Roadmaster Powerplus
The Pursuit and Roadmaster Powerplus Signature Series use a white base with Revere Red and Vigilant Blue graphics, forming a visual interpretation of Indian Motorcycle’s headdress logo. Unlike the Challenger and Chieftain, these two models receive chrome finishes.

Both touring-focused motorcycles also get additional luggage capacity through a top box. Their PowerBand audio system features six speakers and produces 600W, compared with the four-speaker system offered on the Challenger and Chieftain.

Shared engine and limited availability
All four motorcycles use the 1,834cc PowerPlus 112 V-twin, equivalent to 112 cubic inches, delivering 126hp and 180Nm of torque. No major mechanical changes have been announced, with the Signature Series focusing primarily on exclusive styling, premium finishes, touring equipment, and collectability.

Indian Motorcycle says the Signature Series will be produced in “extremely limited” numbers, although it has not revealed the exact production cap. The combination of anniversary-specific paintwork, upgraded equipment, and limited availability is expected to make these motorcycles particularly attractive to collectors and Indian Motorcycle enthusiasts.
