ACE & SPRINGFIELD
1927 – Indian Springfield
Engine: 42ci (≈700cc) side-valve V-twin
Cooling: Air-cooled
Drive: Chain drive
A mid-capacity V-twin positioned between the Scout and the Chief
Designed to offer more power and presence than the Scout, without the size or weight of the Chief
Named after Springfield, Massachusetts, reinforcing Indian’s identity and manufacturing heritage
Following Indian's acquisition of Ace Motor Corporation
1927 – Indian Ace Four
Engine: Inline four-cylinder
Cooling: Air-cooled
Drive: Chain drive
Indian’s adoption of the Ace inline-four, following its acquisition of Ace Motor Corporation
Aimed squarely at the luxury and high-performance end of the market
Exceptionally smooth, powerful, and refined compared with contemporary V-twins
Positioned above the Scout and Chief as a prestige flagship
Indian Ace (Transitional Four)
Year: 1928
Manufacturer: Indian Motorcycle
(design lineage from Ace Motor Corporation)
Engine: Inline four-cylinder
Cooling: Air-cooled
Drive: Chain drive
The 1928 Indian Ace sits at a very specific and important point:

Increasingly Indian-built and Indian-finished
Indian Four
Year: 1929
Manufacturer: Indian Motorcycle
(design lineage fully absorbed from Ace Motor Corporation)
Engine: Inline four-cylinder
Cooling: Air-cooled
Drive: Chain drive
What “fully absorbed” means in 1929
The Ace Four design is now completely integrated into Indian’s engineering, production, and branding
Indian-standard frames, cycle parts, finish, and quality control replace transitional Ace carryovers
The Four becomes a core Indian model, not a legacy holdover
1930–1939
duPONT ERA & REFINEMENT
When Indian motorcycles became industrial art
Under E. Paul du Pont (1930–1945), Indian did not radically redesign its engines. Instead, the company focused on quality, styling, finish, colour, and refinement, transforming proven machines into some of the most iconic motorcycles ever built.

FINAL YEARS & COLLAPSE (1946–1953)
Indian Chief 1946
Engine: 61–74 cu in (≈1000–1200cc) side-valve V-twin
Cooling: Air-cooled
Drive: Chain drive
Retained the iconic valanced-fender Chief styling established pre-war

Indian Warrior
Year: 1948
Manufacturer: Indian Motorcycle
Engine: 440cc vertical (parallel) twin
Cooling: Air-cooled
Drive: Chain drive
Introduced as part of Indian’s post-war attempt to modernise its lineup
Used a British-style vertical twin, a sharp departure from Indian’s traditional V-twins
Intended to offer a lighter, more economical motorcycle for a changing market
Suffered from reliability problems, including lubrication and durability issues
Indian Vertical Twin Scout (Post-war)
Engine: 500cc vertical twin
A radical departure from Indian’s traditional V-twin identity
Powered by a British-style vertical (parallel) twin, reflecting post-war market pressure

Vindian (Vincent–Indian Prototype)
Year: 1948–1949
Engine: 998cc overhead-valve V-twin (Vincent)
Companies: Indian Motocycle Manufacturing Company (USA) & Vincent HRD (UK)
Why:
The Vindian was a late-1940s experimental collaboration intended to modernise Indian’s ageing Chief. By fitting Vincent’s world-leading 998cc OHV V-twin engine into an Indian Chief chassis, the project aimed to create a high-performance American motorcycle capable of competing with emerging European designs and leapfrogging Harley-Davidson.
Only two prototypes were built, and the project was abandoned due to cost, complexity, and Indian’s worsening financial position.
