Let’s start with the engine. Before 2020, you could only get the Thunder Stroke 116 as an upgrade for the 111ci engine, but now the 1,890cc V-twin will come standard on select models straight from the factory. You'll see it on seven bikes: the Springfield Dark Horse, Chieftain, Chieftain Dark Horse, Chieftain Limited, Chieftain Elite, Roadmaster, and Roadmaster Dark Horse. The air-cooled V-twin boasts a new high-flow cylinder head that boosts claimed grunt to class-leading 126 pound-feet of torque (from 119 pound-feet). The 116 also comes with Indian’s rear cylinder deactivation to help keep the engine cooler at low speeds or stopped traffic. The Chief Dark Horse, Chief Vintage, Springfield, and Chieftain Classic however will keep the original 1,811cc mill, while the Chieftain is available with both engines.
