Pros and Cons in comparison

Pros and Cons in comparison

KTM 690 SMC R 2021

KTM 690 SMC R 2021

A large, powerful single cylinder, a stable chassis, just over 160 kg of tractive weight and modern electronics for support - the key data alone suggests a lot of riding pleasure. In 2024, the SMC-R may be a little dusty in some respects and is no longer the undisputed queen of road-legal supermotos, but it can still offer a lot of supermoto fun and performance.

Powerful engine

Electronics can support safety or supermoto manoeuvres as required

Stable, fully adjustable suspension

Agile riding performance

Good ergonomics

Low fuel consumption

Great quickshifter

Old LC display and halogen headlights no longer up to date

Suspension could absorb small bumps more harmoniously

Brakes not overly sensitive

Aprilia's SX 125 is a very sporty supermoto that does justice to Aprilia's long 125cc history. Its 15 hp single-cylinder inspires with its balanced character with high suitability for everyday use, but at the same time provides a lot of fun under the helmet. The biggest advantage it has over the competition is its ABS system, which only acts on the front wheel and was installed instead of a CBS system. This makes it possible to conjure up beautiful drifts on the asphalt, as befits a true supermoto.
