This isn’t the first time that the next-generation KTM 390 Duke has been spotted testing in India. 

• Next-gen KTM 390 Duke caught testing again in India. 
• The upcoming single-cylinder naked motorcycle could feature bigger displacement. 

In fact, from the previous sighting, we already conclude that the upcoming 390 Duke will feature a revised engine and rerouted exhaust system.

However, there’s also an ongoing rumour that the 390 Duke will get a bump in displacement to 399cc. 

In an exciting development, the latest spy shot does suggest that the next-gen 390 Duke sports a larger radiator with a twin-fan setup (the current model only has one) as reported by AutoCarIndia. 

This could suggest that the upcoming model offers more power, likely due to the increase in displacement. 

While the turn of events sounds exciting, there is also the possibility that the extra fan is simply to help improve cooling for the current engine, similar to the one found in the 390 Adventure.

Also, the spy shot revealed a revised swingarm, assuming it’s lighter than the current model. The test mule also features a sharper fuel tank design, redesigned headlight and a wider saddle.

The new 390 Duke is expected to be launched sometime this year.
