BMW F 450 GS 2026

With the F 450 GS, BMW has made a convincing entry into the highly competitive A2 enduro bike segment. The 420 cubic centimetre two-cylinder engine impresses with its smooth running and linear power delivery, where single-cylinder competitors annoy with raw vibrations. The suspension shines with sporty agility and enduro bike comfort in equal measure, while the electronics work discreetly in the background. The Bavarian shows weaknesses when it comes to the accessibility for short fingers on the brakes and clutch lever and the lack of cruise control. Anyone looking for a versatile, high-quality enduro bike for an A2 licence and beyond will find a coherent overall package in the F 450 GS. The Easy Ride clutch rides amazingly well and offers comfort and safety in equal measure. Less experienced riders in particular benefit significantly here, which is a unique selling point in this segment!
