Pros and Cons in comparison

Yamaha R125 2019

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

Kawasaki Z650 2023

The Kawasaki Z 650 is probably the most docile motorbike in the naked bike segment. And that is to be understood in an absolutely positive way - as long as you are not particularly tall and heavy. It is slim, light, agile and accessible. All the controls, but also the engine, do not overwhelm. If you are looking for spectacular performance, you should go for the Z 900, but if you are looking for a nimble and easy-to-ride motorbike, you will be satisfied.

Very accessible handling

Very compact and easy to manoeuvre

Motorcycle appears light and compact

Gives small riders a lot of confidence

Adjustable levers

Not enough space on the bike for tall riders

bike looks a class smaller than 650cc overall

engine looks a bit tame

very defensive seating position

handlebars too narrow and cranked too much for a naked bike.
