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 new R1 is a big hit and no longer compares to the previous model. This was considered a good country road bike and heavy investments had to be made for excursions to the race track. Now it is the other way round. The new R1 has been developed with a clear focus on the race track. The electronics package seems outstanding, technology freaks will get their money's worth. Yamaha fans have to buy it, they finally have a worthy motorbike. The R1 has slight weaknesses when braking - it becomes a little unstable here. If you want to buy a ready-made racing bike without having to work on the chassis, you'd better go for the R1M. The Öhlins electronic suspension works perfectly and has no weaknesses. For pure racetrack use, the second weakness of the R1 can easily be ironed out. The torque hole in the middle can be easily ironed out with a new mapping.

crazy sound

rev-happy engine with strong peak
