Pros and Cons in comparison

Kawasaki Z900 RS 2021

A timelessly beautiful motorbike, the Z 900 RS. Its heart, the powerful and silky-smooth four-cylinder, ensures absolute riding pleasure. Even for longer rides, it offers plenty of comfort thanks to its pleasant seating position, well-padded saddle and high, wide handlebars. For those who like retro motorbikes but appreciate modern handling, the Z1 Homage is a very good choice.

authentic, beautiful retro look

very comfortable seating position

easy and comfortable to ride

no quickshifter and no driving modes (but TC adjustable)

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.

High stability in long radii

agile, high-revving boxer engine

good looks

comfortable seating position

extensive list of accessories

great ESA chassis.

High weight noticeable in tight bends

windshield could be higher

many compulsory features at extra cost

somewhat sluggish
