Indian patent for new tourer

Classic look, modern water-cooled V2

Current patent drawings show that Indian is working on a new tourer that is based on the Challenger – with a water-cooled V2 and aluminum frame, but rolls in the classic design of a US tourer.

2019 presented I.ndian with the Challenger, an excavator that marks the only tourer in the model range with the new 1,768 cm³ and 122 hp V2 that rolls with a water-cooled engine and over 100 hp. The latest patent drawings indicate that Indian is now planning to build a tourer in a classic look with the water-cooled engine. The Roadmaster and the large Chieftain models have so far been powered by the air-cooled 116 Thunder Stroke, which generates 92 hp at 4,200 rpm from 1,890 cm³ (116 cubic inches) and a maximum torque of 168 Nm at 2,800 rpm.

Airbox and air filter in an aluminum frame

The water-cooled V2, on the other hand, which we already know from the Challenger, provides 122 hp at 5,500 rpm and 178 Nm at 3,800 rpm. It’s the most powerful engine in a US tourer anywhere. In addition – as with the Challenger – the aluminum frame of the new Indian tourer. The special thing about this frame construction: The intake air for the engine is passed through the frame and filtered, so it integrates the airbox and the air filter. The air enters the frame through the three holes that are made on the underside of the frame (see picture 8, item 62). From there it passes through a filter (Fig. 7) before it is directed upwards into the fuel injection system. As with the Challenger, an additional inlet can optionally be added on the right side, mimicking the normal V-twin air filter.

Whether the patent drawings are a completely new model or whether existing models such as the Roadmaster or the Chieftain series are being upgraded with the new engine and aluminum frame cannot be seen from the pictures. Visually, the drawings are definitely close to the Roadmaster. The covers attached to the crash bars in front of the footrests, which serve as wind deflectors, as well as the shape of the windshield and front fairing, refer to the Roadmaster. Whereby the front fairing – unlike Chieftain and Roadmaster – is inclined forward and in this area is more like the Challenger.

The front paneling refers to the Challenger (in blue, left), the wind deflectors for the legs are reminiscent of the Roadmaster (in black, right).

Conclusion

Either way, we assume that the water-cooled V2 will gradually find its way into the large Chieftain models and the Roadmaster thanks to the current emissions regulations. In terms of emissions, it is simply one step ahead, and it is currently the most powerful V2 in terms of US touring engines.
