What is the Indian Motorcycle Signature Series?
Indian Motorcycle has introduced its Signature Series, commemorating its 125th anniversary. The Signature Series is commissioned to highlight the brand’s craftsmanship and selection of finer details, rather than a mechanical upgrade.

Which models are part of the range?
The Signature Series includes four motorcycles:
-
Challenger
-
Chieftain PowerPlus
-
Pursuit
-
Roadmaster PowerPlus
The Signature Series lineup is split between bagger and full touring formats. The Challenger and Chieftain PowerPlus are the bagger-style models, while the Pursuit and Roadmaster PowerPlus are the touring versions.
What engine do these bikes use?
All four models use India’s liquid-cooled PowerPlus 1,834 cc 112 V-twin engine. The engine produces 126 hp and around 180Nm of torque, with a six-speed gearbox.

What are the styling changes?
The Signature Series is centred around visual enhancement. The Signature Series uses a multi-layer paint process with hand-finished detail, creating more depth, sharper contrast and a more custom-like appearance compared to the standard models.
The Challenger and Chieftain PowerPlus get a darker, blacked-out treatment with premium accent colours, while the Pursuit and Roadmaster PowerPlus wear a more chrome-rich, red-white-blue inspired scheme.
What features are added?
The Signature Series keeps the PowerPlus family’s touring-oriented equipment; Challenger and Chieftain PowerPlus get a 400W PowerBand audio system; Pursuit and Roadmaster PowerPlus get a 600W audio system with additional speakers in the trunk.
The Signature Series models retain the PowerPlus safety and rider-assist suite, including lean-sensitive ABS, traction control, electronically linked braking, bike hold control, blind-spot warning and rear-collision warning.

How does it differ from the 125th Anniversary Collection?
The Signature Series and the 125th Anniversary Collection are related but not the same. The 125th Anniversary Collection was a broader special-edition line featuring models such as the Chief Vintage, Scout Bobber, Challenger and Roadmaster. While the Signature Series is solely focused on the modern PowerPlus touring family.
