BMW R 1250 GS Adventure 2023

BMW R 1250 GS Adventure 2023

The big GS Adventure is and remains a great motorbike for any terrain - even for tight corners. The low centre of gravity of the boxer engine, the longitudinally mounted crankshaft, the upright seating position and the powerful but easily controllable torque from far below are simply a force. Although the Adventure version has a higher seat with more weight, which is a decisive hindrance when turning or manoeuvring, in terms of performance the engine also has so much punch in the big GS Adventure that you can let it rip. The BMW's braking system is stable and excellently controllable, and the equipment and electronics can be upgraded considerably - as long as you tick the boxes on the order list. Of course, this pushes up the price, but the many fans of the fat GS Adventure obviously don't mind.

High-torque engine that accelerates strongly from low revs

low centre of gravity ensures surprisingly accessible manoeuvrability

practical details for frequent riders on board

gigantic range of 600 km

amazingly low consumption

good wind and weather protection

great ride comfort

powerful engine

great electronics

easy-to-read display

confident feeling in the saddle

practical riding aids

High weight

gearshifts at low revs somewhat clumsy

jagged appearance with little elegance

high-priced with full equipment

Kawasaki Z900 2022

Kawasaki Z900 2022

The Kawasaki Z900 may not be up to scratch when it comes to modern, lean angle-dependent electronic features, but it's relatively cheap and you shouldn't underestimate the fan base of the good old inline four - the Z900 is one of the cheapest ways to own such a great engine with just under a litre of displacement in a sporty naked bike! The higher weight is noticeable, but not massively annoying, because the handling and stability are quite alright. In terms of "outdated" electronics, the most annoying thing is the missing shift assistant, which is not even available as an option. Overall, however, the Z900 is a great naked bike with a great price-performance ratio.

Light and natural handling with high stability

silky engine with full pull from low revs

high chassis transparency, great feedback

seating position with feel-good factor

absolutely fair price.

Relatively cumbersome operation of the menu

no slope-dependent assistance systems

high weight
