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
