KTM has always been that wild child of the motorcycle world—raw, rebellious, and ready to raise some hell. And with the KTM 990 Duke, the Austrian brand has once again proved it’s not afraid to break the rules. If you thought the 890 Duke R was insane, brace yourself—the 990 is here, and it’s sharper, meaner, and more thrilling than ever.
But is this new Duke just an evolution or a total revolution? Let’s crack it wide open and find out what makes this bike a serious contender in the middleweight naked segment.
Design & Styling: Still Naked, Now Meaner
If looks could kill, the KTM 990 Duke would leave a trail of smoldering helmets in its wake. One glance and you’ll know—it’s unmistakably a Duke, but with an extra dose of venom. The sharp LED headlight now resembles something out of a sci-fi thriller. Angular tank shrouds, exposed frame, and that menacing stance scream, “Don’t mess with me.”
KTM’s signature orange trellis frame still shines through, but the overall aesthetics have matured. It’s like the Duke hit the gym, got ripped, and came back with a vengeance. The new fuel tank design blends aggression with functionality, offering better ergonomics while still keeping that streetfighter DNA intact.
Also, can we just take a second to appreciate the tail section? Sleek, compact, and perfectly balanced. It’s as if the design team used a scalpel instead of a pencil—everything looks precise.
Engine & Performance: The Real Deal in the Middleweight Class
Let’s talk power—because that’s what you’re really here for, right?
The KTM 990 Duke is powered by a 947cc parallel-twin engine, pushing out a jaw-dropping 123 hp and 103 Nm of torque. That’s not just middleweight muscle—that’s full-on street brawler power. KTM calls this engine the LC8c, and it’s lighter, more compact, and punchier than ever.
This thing doesn’t just accelerate—it launches. Twist the throttle in second gear, and the front wheel wants to lift. Yet, it’s surprisingly rideable. The torque is spread well across the rev range, so whether you’re zipping through city traffic or hammering down a country road, the 990 Duke always feels alive.
It’s got a 6-speed gearbox with a bi-directional quickshifter that works like magic. Gear changes feel like slicing through butter with a hot knife—clean, crisp, and fast. And thanks to the slipper clutch, aggressive downshifts are smooth as silk.
Ride & Handling: Razor-Sharp with a Side of Confidence
When it comes to handling, the 990 Duke is a scalpel in a world of hammers. It doesn’t just take corners—it attacks them. The chassis is new and lighter, paired with top-tier WP APEX suspension—43mm USD forks up front and a monoshock at the rear.
Now, here’s the best part—it’s fully adjustable. So, whether you’re a weekend canyon carver or a track day junkie, you can fine-tune it to your heart’s content.
The bike sits on 17-inch cast wheels wrapped in sticky Michelin Power GP tires, which offer incredible grip. The wheelbase is slightly longer than the 890, giving it more stability without sacrificing flickability.
And let’s not forget the brakes—dual 300mm discs with radially mounted 4-piston calipers at the front and a 240mm disc at the rear, backed by cornering ABS. Brake hard, lean in, and the Duke just obeys. No drama, just performance.
