The bike’s fuel capacity of 12 liters (3.17 gallons) strikes a balance between weight and range, allowing for spirited rides without constant refueling. Riders will appreciate the adjustable seat height of 880 mm (34.6 inches), accommodating a variety of rider sizes and preferences. Available in striking color options of silver/black or green/black, the Duke II is not only functional but also a head-turner on the road. **

Pros

  • Agile Handling: The lightweight design and powerful engine provide exceptional responsiveness and maneuverability, ideal for both city and twisty roads.

  • Unique Design: The KTM 640 Duke II showcases a distinctive aesthetic that stands out in the super motard category, appealing to riders who value style.

Cons

  • Limited Fuel Capacity: While adequate for short rides, the 12-liter tank may require more frequent stops on longer journeys.
  • Minimal Wind Protection: The bike’s design is focused on agility, which means it lacks significant wind protection, potentially leading to rider fatigue on the highway.
