Pros and Cons in comparison

Pros and Cons in comparison

BMW S 1000 R 2021

BMW S 1000 R 2021

It's really impressive how BMW always manages to make good motorbikes even better. The sporty S 1000 R with M package and carbon rims looks a bit threatening at first. But even in 2021, the S 1000 R serves up high-tech and performance in a grandiose, usable dosage. The machine rides precisely, handles well but is not tippy. The engine fires out of the corners, but does not overtax. A damn fast motorbike!

Powerful engine

good brakes

comfortable ergonomics

high-priced but high-performance optional extras

simple operation but still very fast

great all-rounder.

Quickshifter good, but not perfect, sound still a bit intrusive

still with vibrations in handlebars

BMW F 900 R 2025

BMW F 900 R 2025

The BMW F 900 R remains a prime example of common sense on two wheels in 2025. It does not impress with radical looks or a brute engine - but that is precisely its strength. If you are looking for a reliable, versatile naked bike suitable for everyday use that offers solid technology, modern safety features and a fair price-performance ratio, this is the bike for you. The model upgrade brings sensible improvements to details without overloading the tried and tested concept.

Price-performance ratio

Riding modes incl. Dynamic mode as standard

New, adjustable fork

ABS Pro and DTC as standard

Revised ergonomics: sporty but comfortable

Pleasant handling, accessible riding dynamics

Good workmanship, solid technology

Design still rather restrained, not very emotional

Quickshifter is stiff at low revs

Suspension set-up at the rear more geared towards comfort than sport
