According to reports from various American media outlets – including colleagues from Motorcycle.com – Indian is working on a new version of the PowerPlus engine that currently powers the Challenger and Pursuit models and is the only liquid-cooled engine from the American manufacturer. The most interesting news is that it would be destined for bagger and touring models, namely the Chieftain and Roadmaster. The debut would be quite imminent, as the year 2025 is mentioned.
Confirming this assumption is an internal document from the American manufacturer that contains details about the upcoming models. A vehicle identification code for the 2025 model year lists the new liquid-cooled models as Chieftain PowerPlus and Roadmaster PowerPlus, as well as the new engine displacement of 1834 cc. This engine is presented alongside the current 1768 cc (108ci) PowerPlus that powers the Pursuit and Challenger. There are also four levels of finish: base, Dark Horse, Elite/Limited Edition, and Limited. It is not clear whether the larger engine will be used in all Chieftain PowerPlus or Roadmaster PowerPlus models, or if it will be reserved for specific equipment. What is certain is that with the two new PowerPlus models, Indian’s liquid-cooled touring range will offer four models instead of just two. Therefore, those who want a protective fairing mounted on the frame can choose between the Challenger bagger or the Pursuit tourer with a passenger backrest/cradle. Those who prefer the classic fairing mounted on the forks have the Chieftain PowerPlus bagger and the Roadmaster PowerPlus tourer at their disposal.
However, those who are horrified by the idea of a liquid-cooled engine and who love the Thunderstroke 116 engine have no reason to worry, as the same documents show that the air-cooled versions of the Roadmaster and Chieftain will remain in the lineup at least until 2025. This is why the liquid-cooled versions will be distinguished by the “PowerPlus” specification.
