Pros and Cons in comparison

BMW F 900 R 2021

The BMW F 900 R is a full-grown motorbike. 895 cc, 105 hp and 92 Nm smell of versatility. The F 900 R fulfils this promise completely. The motorbike, including electronics and components, does a great job in every situation. But of all things, the heart of the bike, the engine and transmission unit, does not shine in premium gloss.

Great cockpit and functional connectivity

Extensive electronics can be operated logically

Very accessible but still very casual handling

Motorcycle rides bland and reserved but also wild and sporty when needed

Pleasant seating position

Wide choice of equipment and configuration options

Low and high seat options available

Suspension allows wide range of use - comfortable but also direct and precise.

Gearstick a little stiff - with and without quickshifter

Engine runs a little rough and exudes little elegance at the top

Poor splash guard at the rear

Yamaha YZF-R125 2021

The Yamaha YZF-R125 in the 2019 version makes journalists' lives difficult. You search and search for a fault, but can't find one - simply frustrating! Because the 15 hp single-cylinder with variable valve timing (VVA) performs excellently and is undoubtedly one of the best power units in the 125cc class. The handling is convincing in everyday life as well as on the racetrack, even if the chassis shows its sporty side on bumps. But we are on a super sports bike, so that is not a serious point of criticism. Maybe I need to ride the R125 for a few weeks to find its Achilles heel after all....

excellent engine

cool looks

sporty chassis

very potent on the racetrack

very good supersport package

unfortunately nothing
