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

The mere fact that the Kawa Ninja ZX-4RR with its high-revving Inline four-cylinder engine in bonsai format has no real competition makes it absolutely unique. The engine is also the absolute flagship, with a rev limit at 16,000 touring you'll be addicted to wind out a gear! The suspension, brakes and electronics are of a high height, but what is more surprising is that, despite all the sportiness, the bike is still very suitable for everyday use - the seating position is not as radical as on other supersports bikes.

Fun in-line four-cylinder

precise quickshifter with blipper

balanced handling

sporty and pleasant ergonomics

comprehensive electronics package

Engine needs to be kept happy

looks confusing with other Kawasakis
