BMW launched pretty heavily revised S1000RR and M1000RR models this year, but I'd argue that the announcement of the all-new Concept F 450 GS grabbed the attention of a far wider audience. It makes sense, as the lightweight ADV segment is popping off right now with exciting models from the likes of Triumph and KTM, and the fact that the outgoing GS 310 is a fairly woeful offer in comparison to what else is available.
When RideApart's Executive Editor, Jonathon Klein, first heard about the Concept F 450 GS late last year, to describe him as "excited" would be an understatement, and his thoughts echoed plenty of riders who were waiting for BMW to up its game in this category.
Just based on the lines and ergonomics of the concept, along with a sweet Akrapovič end can, the German manufacturer appears to have taken this model seriously Now, the official concept model is about to be unveiled.

The 52nd Tokyo Motorcycle Show will play host to the unveiling of the official Concept F 450 GS, and here's an outline of how the event will unfold:
Press Conference
Date and time: Friday, March 28th, 10:05-10:20.

The event has also been selected by BMW to unveil the R20 Concept and prices of the latest M1000RR, M1000R, and S1000R. In total, there'll be 23 of Bavaria's finest models on display, including a special exhibit of the R 18 series in its 2025 color scheme.
I think a lot of opinions are waiting to be formed until BMW announces how much the production F450 GS will cost. What's the most you're willing to pay for a lightweight adventure bike?
