KTM has introduced a new version of the KTM 390 Duke with a smaller 349cc engine to benefit from lower GST taxes in India. At the same time, the bigger engine version is now called the KTM 390 Duke R. Both bikes are sold together, but they are aimed at slightly different riders—one focuses on value, the other on performance.
What Remains the Same
In real-world use, both bikes feel very similar because KTM has kept most of the hardware unchanged. They share the same Gen-3 chassis, suspension setup, braking system, and overall dimensions. This means handling, comfort, and ride quality are almost identical.
- Same steel trellis frame with aluminium subframe
- WP Apex USD forks and rear monoshock
- 320mm front disc & 240mm rear disc
- Same weight (168.3 kg)
- Identical TFT display and electronics
Simply put, you’re not losing any premium features by choosing the cheaper model.
Engine & Performance
The real difference comes from the engine. The standard Duke uses a smaller engine, while the Duke R keeps the more powerful one.
| Specification | KTM 390 Duke | KTM 390 Duke R |
|---|---|---|
| Engine | 349.3cc | 398.63cc |
| Power | 41.5 hp | 46 hp |
| Torque | 33.5 Nm | 39 Nm |
The Duke R clearly offers stronger acceleration and better top-end performance. Since both bikes weigh the same, the extra power makes a noticeable difference on highways and spirited rides.
Design Difference
Design-wise, both bikes look aggressive and modern, but small visual changes help you tell them apart. The standard Duke comes with a black frame and “390” branding, while the Duke R gets KTM’s signature orange frame and more bold “Duke” graphics.
Price Difference
| Model | Price (Ex-showroom) |
|---|---|
| KTM 390 Duke | ₹2.77 lakh |
| KTM 390 Duke R | ₹3.39 lakh |
The Duke R is about ₹62,000 more expensive, mainly for the bigger engine and added performance.
Which One Should You Choose?
If you mainly ride in the city and want a powerful yet practical bike, the standard 390 Duke makes more sense. It offers the same features and hardware at a lower price.
However, if you enjoy aggressive riding, highway performance, and want the most power possible, the Duke R is the better pick.
- Value & daily use → 390 Duke
- Performance & thrill → 390 Duke R
Final Thoughts
KTM has smartly created two options without compromising on features. The standard Duke is more accessible and practical, while the Duke R is built for enthusiasts who want extra performance. Your choice ultimately depends on how much you value that extra power.
