Aprilia SR GT 400 2026

Aprilia SR GT 400 2026

The Aprilia SR GT 400 impressively demonstrates how much riding dynamics and quality can be found in a mid-range scooter today. In particular, the stable, high-quality suspension and the direct reponsiveness of the 400cc single cylinder ensure that the scooter feels much sportier and of a higher quality than you would expect in this class. At the same time, it remains suitable for everyday use thanks to good ergonomics, practical storage space and reasonable wind and weather protection. Minor weaknesses such as the somewhat sluggish operation of the display are of little consequence in the overall picture. Combined with a fair price, the result is a very convincing overall package for anyone looking for a sporty, stable and versatile scooter.

KTM 390 SMC R 2026

KTM 390 SMC R 2026

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
