If you’ve been browsing forums, scrolling through YouTube reviews, or hanging around bike meetups, chances are you’ve heard this debate: KTM 390 Duke vs Royal Enfield Continental GT 650.
Both motorcycles live in that sweet middleweight segment — not too intimidating, not too underpowered — making them great picks for riders who want more thrill than a 150cc commuter but don’t want the wallet-crushing commitment of a 1000cc superbike. But here’s the real question: which one should you spend your money on in 2026?
In this blog, we’ll dig into both bikes with a rider-friendly lens, referencing real-world feedback from forums and communities. Whether you’re chasing speed, comfort, or everyday usability, this head-to-head comparison will help you figure out which bike fits your riding style.
KTM Duke 390 vs Royal Enfield Continental GT 650
Before we dive into the details, here’s a quick at-a-glance table:
| Spec | KTM 390 Duke | Royal Enfield Continental GT 650 |
|---|---|---|
| Engine | 373cc, single-cylinder, liquid-cooled | 648cc, parallel twin, air/oil cooled |
| Power | ~45 hp | ~47 hp |
| Torque | ~37 Nm | ~52 Nm |
| Weight | ~171 kg (dry) | ~198 kg (dry) |
| Seat Height | ~830 mm | ~804 mm |
| Price (2025 est.) | $5,899 (USA) | $6,999 (USA) |
They’re surprisingly close in power. But the way they deliver that power — and the riding experience that comes with it — is completely different.
Engine Character: Punch vs Smoothness
390 Duke:
This is where KTM shines. The 390 Duke’s single-cylinder is aggressive, punchy, and rev-happy. Riders on forums often describe it as “a hooligan in a small package.” It begs to be revved hard, and when you twist the throttle, you get an immediate surge of acceleration. The downside? It vibrates — especially at highway speeds. If you’re the kind of rider who loves darting through traffic or carving up tight mountain roads, the Duke feels alive in your hands.
GT 650:
The Royal Enfield Continental GT 650 takes the opposite approach. The parallel-twin engine is butter-smooth, with a relaxed, linear power delivery. Forum riders often compare it to “an old-school café racer feel, but with modern reliability.” You don’t get the instant punch of the Duke, but you get more torque, which means you can roll on the throttle without constantly downshifting. Perfect for cruising highways, long weekend rides, or showing up at a café with vintage vibes intact.

Riding Position & Comfort
390 Duke:
KTM designed the Duke to be upright, comfortable, and super maneuverable. The wide handlebars, high seat, and light weight make it excellent for city commuting. However, taller riders on forums sometimes complain about the cramped feel on long rides. Plus, the stiff suspension, while fun in corners, can be unforgiving on rough roads.
GT 650:
The Continental GT 650 is styled like a true café racer. Clip-on handlebars, rear-set pegs, and a lower seat height create a sportier, leaned-forward stance. It looks cool, no doubt. But if you plan to ride long distances, your wrists and back may not thank you. Riders often mention swapping bars or adding comfort mods to make it more livable.

Technology & Features
390 Duke:
-
TFT color display with Bluetooth connectivity
-
Ride-by-wire throttle
-
ABS with cornering function
-
Quickshifter (on newer models)
-
Lightweight trellis frame & WP suspension
For a bike under $6k, that’s a seriously premium feature set.
GT 650:
Royal Enfield plays it old school. You get a simple analog-digital display, dual-channel ABS, and basic electronics. No fancy TFT, no quickshifter, no riding modes. Some riders love this simplicity — less to go wrong, more raw connection with the bike. But if you’re tech-hungry, you’ll feel left behind.

Tech lovers → 390 Duke

Purists & retro fans → GT 650
Maintenance & Reliability
390 Duke:
KTM’s reputation is a double-edged sword. On one hand, the bike is performance-packed and fun. On the other, some riders complain about higher maintenance costs and occasional reliability issues, especially in hot climates or with rough use. Regular oil changes, valve checks, and attention to the cooling system are non-negotiable.
GT 650:
Royal Enfield has massively improved reliability compared to its past reputation. The GT 650’s engine is under-stressed and built for durability. Riders report putting 30,000+ miles with little more than routine maintenance. Parts are relatively cheap, and the brand’s global dealer network has expanded a lot.

Willing to pay for performance → 390 Duke
-
Want long-term reliability → GT 650

Final Thoughts
The KTM 390 Duke and Royal Enfield Continental GT 650 are both fantastic motorcycles, but they serve two very different personalities. The Duke is like that friend who always convinces you to stay out late and do something wild. The GT 650 is the chill buddy who wants to grab coffee, talk about music, and take a road trip on the weekend.
At around $6k–7k, neither bike will break the bank, but the memories you’ll make with them are priceless.
So, which one are you choosing in 2025: the Duke 390 or the GT 650?
