Pros and Cons in comparison
Pros and Cons in comparison
KTM 690 Duke 2018

Considering where the KTM Duke family once started, the 690 Duke is an incredible step forward. The engine is extremely refined and at the same time husky for a street-legal single-cylinder. Despite all the technology on board, it is still a very light motorbike and can almost be called a toy (in a good sense). Only its seating position divides opinions, because with the Duke 4 in 2012, the former supermotos became an almost tame naked bike with a front-wheel-oriented seating position. The advantage: everyday life and long tours should not be a problem on the current Duke.
Kawasaki Z650 2021

Even in 2021, the Kawasaki Z 650 stands for easy riding with great looks and good equipment. Both seat height and engine are very accessible and will give both experienced riders and newcomers a lot of pleasure. If you are looking for an honest naked bike without any big surprises, this is the bike for you. Due to its compact dimensions, however, you should try it out before buying and perhaps go for the raised seat.
