KTM 390 SMC R 2025

The KTM 390 SMC R is neither a slimmed-down 690 nor a disguised Duke derivative, but an independent interpretation of the supermoto theme - accessible, suitable for everyday use and yet with enough sharpness for serious lean angles. It does not have a brute radicality, but a clever overall package that confidently covers urban riding, after-work laps and occasional track excursions. The engine is revvy, the suspension can be fine-tuned, the brakes work exceptionally well and the ergonomics allow you to ride a longer stage - without having to fish your knees out of the petrol cap one by one afterwards. With an entry-level price of €6,299 in Germany (plus ancillary costs) and €6,999 in Austria (incl. NoVA), it remains reasonably priced - especially considering the extensive features with TFT display, traction control, supermoto ABS and an optional quickshifter. In short: If you are looking for an A2-compatible bike with character that is not only easy to ride but also easy to understand, the 390 SMC R is a successful blend of rationality and lateral behaviour. And in the end, that is perhaps exactly what the supermoto market has been missing.

Attractive entry-level price with extensive standard equipment

Revviness, powerful single cylinder

Lengthy service intervals (10.000 km)

Agile, stable and easy to control - also for beginners

WP APEX suspension adjustable

Good balance between sportiness and everyday comfort

Stable front brake (320 mm, Bybre)

Supermoto ABS can be deactivated at the rear wheel/ Clear pressure point

Successful look with underfloor exhaust

Full-length seat, comfortable seat height (860 mm)

Adjustable footrests, good ergonomics details

Agile, neutral steering behaviour/ Well-tuned gear ratio

Relatively heavy for a 390 (163 kg full tank) - due to A2 conformity

seat height for very small riders (under 1.70 m) possibly borderline
