Pros and Cons in comparison

Triumph Scrambler 400 X 2024

If you like a cool scrambler look but need to stay in the A2-compatible range when it comes to the engine, the Triumph Scrambler 400 X is a really smart choice. The 400cc engine has a nice torque in the mid-range; it doesn't really wind out a gear. The riding position is upright, the suspension is comfortable yet stable. The Scrambler 400 X can therefore also be ridden in a sporty manner, although the front brakes require too much manual force when ridden with vigour. On the other hand, the features are generous with the many off-road orientated attachments and put the higher price into perspective compared to the naked Speed 400 sister.

high-quality modern-classic look

good price

engine with strong centre

responsive suspension

good, model-matched tyres

Weak brakes at the front

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 take a longer ride - 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 (€ 6,299 DE / € 6,999 AT) with extensive standard equipment

Revvy, powerful single cylinder with 45 Horsepower / 39 Newton metres

Lengthy service intervals (10.000 km)

Agile, stable and easy to control - even for beginners

WP APEX suspension fully adjustable (front & rear)

Good balance between sportiness and everyday comfort

Stable front suspension (320 Millimetres, Bybre)

Supermoto ABS can be deactivated at the rear wheel/ Clear pressure point - even on the kart track

Successful look with underfloor exhaust

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

Adjustable footrests, good ergonomics details

Michelin Power 6 - good all-round tyres for road & kart track

Agile, neutral steering behaviour/ Well-tuned gear ratio

Relatively heavy for a 390 (163 kg fully fuelled) - due to A2 conformity

quickshifter only optional (€ 251 surcharge)

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