Pros and Cons in comparison

Honda CB125R 2020

Unfortunately, our editors did not test this model.

BMW G 310 R 2021

Okay, many competitors have disappeared from the BMW G 310 R with more displacement and thus more horsepower. But in the 300cc class, the small R is a really honest naked bike: the engine revs agilely, the handling is lively yet stable, the brakes work satisfactorily and the look is quite convincing with the fat, golden fork and the modern elements.

Engine revs nicely

well-behaved brake

beautiful appearance

pleasant seating position

Less power than the competition
