KTM 390 SMC R vs 690 SMC R – Which Supermoto Makes More Sense?

With the launch of the KTM 390 SMC R in 2025, KTM is re-entering the smaller Supermoto segment for the first time in years, raising a pivotal question: Is the big 690 SMC R still necessary? For over a decade, the 690 has been the benchmark in the single-cylinder Supermoto class. But with the introduction of the new, modern, and surprisingly mature 390, it faces serious competition—from its own lineup.

This test reveals how different the two models really are and determines which machine makes more sense for riders today.

Although both models sport the typical KTM Supermoto look, they feel completely different.

The KTM 390 SMC R immediately strikes you as light, playful, and inviting. It's compact, nimble, and almost jittery in its eagerness to move. A bike that actively encourages its riders and gives them the confidence to try new things. Due to its 390 Duke foundation, it features a relatively high tank bump, which prevents direct positioning behind the handlebars. However, newcomers to the Supermoto world shouldn't be too bothered by this.

The KTM 690 SMC R, on the other hand, leaves no doubt about its character even when at a standstill. The big single-cylinder vibrates with life, the sound is robust, and the bike has a serious demeanor. The seating position with its completely flat seat further emphasizes this. This motorcycle isn't just ridden—it's commanded. Its presence clearly states: I'm no toy.

Here, the paths of the two Supermotos diverge significantly. The 390 SMC R delivers 45 horsepower and 39 Nm of torque. While that may not sound spectacular, this setup works brilliantly on the road. The LC4c engine revs smoothly, is highly controllable, and always provides a sense of command. Riders can fully exploit it—a crucial factor for pure riding pleasure. It generously forgives mistakes, with throttle response remaining friendly at all times.

The 690 SMC R is a completely different beast: with 79 horsepower and 73 Nm of torque, it stands as the world's most powerful production and street-legal single-cylinder Supermoto—a title reclaimed from Ducati in 2025. Every twist of the throttle is an event. The torque hits hard, and the engine character is raw and uncompromising. Riding the 690 evokes both fascination and respect—KTM has long demonstrated just how radical a single-cylinder can be.

On paper, the weights of the two models are surprisingly close. However, in practice, the 390 feels noticeably more playful. The KTM 390 SMC R relies on WP APEX suspension components, offering plenty of travel and a pleasantly accessible setup. Its handling is intuitive, eager for corners, and forgiving. In tight rural roads or urban environments, it fully showcases its agility.

The KTM 690 SMC R, on the other hand, is distinctly sportier, featuring a WP APEX 48 mm fork, Pro-Lever linkage, and premium Brembo brakes. It demands more skill, precision, and clear commands. In return, it delivers immense stability, razor-sharp cornering, and maximum performance. The 690 rewards—but it also demands.

According to expert Martin Bauer, modern small displacements can achieve quite a lot these days. They offer agility, low weight, and an accessible entry point. Inexperienced riders, in particular, benefit from the forgiving power delivery of the 390 SMC R. However, Bauer foresees a desire for more power arising as riders gain experience. Small displacements are naturally limited in peak performance. Those who want to ride more intensely and extract the maximum from a single-cylinder will eventually lean towards the 690—even though the 390 continues to be fun.

The price difference is significant:

• KTM 390 SMC R: €6,999 (Austria)
• KTM 690 SMC R: €13,599 (Austria)

This makes the big SMC R nearly twice the price. The premium is reflected in performance, components, and long-term market positioning. The 690 remains an icon and the ultimate choice for experienced Supermoto riders.

The 390 SMC R, on the other hand, opens the door to an entirely new target audience: young riders, A2 license holders, returning riders, and those seeking maximum fun with minimal intimidation. It's not only more affordable but also significantly more accessible in terms of riding dynamics.

The short answer: Yes—but not for everyone.

The KTM 390 SMC R impressively proves that fun doesn't depend on raw power. It's light, playful, modern, and offers a Supermoto experience that makes more sense for many riders than sheer brute force. On tight country roads, in city traffic, or as a sporty entry-level option, it is often the better choice.

The KTM 690 SMC R remains relevant, though. Those seeking maximum intensity, pure single-cylinder power, and overall sporty performance will find it here and nowhere else. The 690 has its place—but today, it's more specific than it used to be.

So, do you need it? Only if you know exactly what you want: raw power, uncompromising performance, and a motorcycle that demands experience. For everyone else, the new 390 SMC R doesn't make the big sister obsolete—but it makes it less necessary than ever before.
