KTM 390 Adventure X Review: Big Bike Feel on a Budget? (2026)

The KTM 390 Adventure X: A Budget Explorer with Untapped Potential

There’s something undeniably appealing about a motorcycle that promises adventure without breaking the bank. The KTM 390 Adventure X is one such machine—a budget-conscious, road-focused variant of the more hardcore 390 Adventure R. On paper, it ticks many boxes for riders seeking a lightweight, versatile bike. But as I delved deeper into its design, performance, and features, I couldn’t shake the feeling that KTM could—and should—have delivered more.

The Heart of the Matter: KTM’s LC4c Engine

Let’s start with what works. The KTM 390 Adventure X is powered by the brand’s trusty LC4c single-cylinder motor, and it’s a gem. Personally, I think this engine is the bike’s saving grace. It’s smooth, strong, and more than capable of zipping up to 70mph without breaking a sweat. What makes this particularly fascinating is how KTM has managed to minimize vibrations, a common gripe with single-cylinder bikes. Sure, it gets a bit buzzy above 80mph, but for most riders, that’s hardly a dealbreaker.

What many people don’t realize is that single-cylinder engines often get a bad rap for being underpowered or frustrating to ride. But KTM’s LC4c defies those stereotypes. It’s responsive, with a throttle connection that feels almost telepathic. If you take a step back and think about it, this engine is a masterclass in balancing performance and efficiency—a rare find in this segment.

The Road-Focused Design: A Double-Edged Sword

The 390 Adventure X is clearly designed for tarmac rather than trails. Its 19-inch front wheel and Apollo Tramplr XR tires are more at home on paved roads than dirt tracks. From my perspective, this is both a strength and a weakness. On one hand, it makes the bike agile and enjoyable to ride in urban and highway settings. The WP Apex suspension, though basic, delivers a surprisingly assured ride quality.

But here’s the thing: adventure bikes are supposed to be versatile. By leaning so heavily into on-road performance, KTM has limited the X’s appeal to riders who want a true dual-sport experience. One thing that immediately stands out is how this bike feels like it’s missing its off-road DNA, which is a shame given the adventure bike trend it’s trying to capitalize on.

The Braking Conundrum: A Weak Link

Now, let’s talk about the elephant in the room: the front brake. It’s weak, spongy, and lacks the confidence-inspiring performance you’d expect from a modern adventure bike. In my opinion, this is a glaring oversight. Braking is one of the most critical aspects of riding, especially on a bike marketed as versatile. The fact that the rear brake feels overly sharp only highlights the imbalance in the system.

What this really suggests is that KTM cut corners where it shouldn’t have. A detail that I find especially interesting is that the 390 Adventure R, the X’s more expensive sibling, doesn’t suffer from this issue. It raises a deeper question: why couldn’t KTM have equipped the X with a better braking system, even if it meant a slight price increase?

The Dash Dilemma: A Budget Option That Feels Cheap

The LCD dash on the 390 Adventure X is a sore spot. It’s basic, hard to read in sunlight, and feels like an afterthought. Personally, I think this is where the bike’s budget nature becomes too obvious. KTM could have easily upgraded to a TFT display, which would have elevated the overall experience without significantly increasing costs.

What many people don’t realize is that small details like the dash can make or break a rider’s perception of a bike. In a segment where competitors are offering more tech-savvy features, the X’s dash feels like a missed opportunity. It’s not just about aesthetics—it’s about functionality and user experience.

The Price Point: Competitive, But Is It Enough?

At £5399, the 390 Adventure X is priced to sell. It’s cheaper than rivals like the Triumph Scrambler 400 X and comes with a 0% APR finance deal. On the surface, this seems like a great deal. But if you take a step back and think about it, the bike’s limitations start to outweigh its affordability.

From my perspective, KTM has prioritized cost-cutting over delivering a well-rounded package. The lack of traction control, adjustable levers, and a cornering ABS function are all reminders that this is a budget bike. While I appreciate the value proposition, I can’t help but wonder if KTM could have struck a better balance between price and features.

The Broader Perspective: Where Does the X Fit In?

The adventure bike segment is booming, with younger riders flocking to rugged, versatile models. The 390 Adventure X is KTM’s attempt to tap into this trend, but it feels like it’s fallen short. In my opinion, the bike’s road-focused design and cost-cutting measures limit its appeal to a niche audience.

What makes this particularly fascinating is how KTM’s single-cylinder models have historically over-delivered on spec while keeping prices low. The X, however, feels like a step backward. It’s a pleasant bike to ride, but it could—and should—have been so much more.

Final Thoughts: A Bike with Untapped Potential

The KTM 390 Adventure X is a budget explorer with a big heart, but it’s held back by its limitations. The engine is fantastic, the ride quality is enjoyable, and the price is competitive. Yet, the weak front brake, disappointing dash, and lack of tech features leave me wanting more.

If you take a step back and think about it, this bike is a prime example of how small compromises can add up to a less-than-stellar experience. Personally, I think KTM has missed an opportunity to create a truly standout budget adventure bike. With a few key upgrades, the X could have been a game-changer. Instead, it’s a bike that feels like it’s playing it safe—and in the world of adventure riding, safe isn’t always enough.
