In terms of strengths, the BMW R 1250 RS offers high stability in long radii, thanks to its stable chassis.

It also comes with a standard electronics package and provides lots of stability thanks to its full fairing. It is also very accessible for riders of all levels.

However, both motorcycles have their weaknesses. The BMW R 1250 RS has a high weight that can be noticeable in tight bends, and the windshield could be higher for better wind protection.

BMW R 1250 RS 2021

BMW R 1250 RS 2021

A great engine in a pretty dress is not everything. The standard equipment of the BMW R 1250 RS is disappointing; neither quickshifter nor cruise control are included, which is no longer in keeping with the times in 2021. Ergonomically, the Bavarian can be adapted to almost any rider. The ESA suspension is great and a must-have extra, especially when there are two of you. In tight bends, the RS's weight is indisputable; here it seems almost sluggish. The wider the radii, the more confident you are on the BMW. Wind and weather protection are good, although a slightly higher windshield would be desirable.

Kawasaki Ninja 1000SX 2021

A sports tourer of the old school. The Kawasaki Ninja 1000SX fulfils all the points you would expect from this bike category. Added to this is a comprehensive electronics package that offers everything you could wish for when travelling - and at no extra charge! The fact that the operation is perhaps not quite as intuitive as the competition already manages, is forgiven at the latest when you take a look at the price tag.

very accessible.

Engine needs revs
