Moving on to the strengths of each model, the Ninja ZX-6R 2006 is known for its anti-hopping clutch, which helps prevent rear-wheel lock-up during aggressive downshifting.

In conclusion, the Kawasaki Ninja ZX-6R 2006 and the Kawasaki Ninja 650 2023 are both impressive models with their own strengths and weaknesses. The Ninja ZX-6R offers more power and performance, while the Ninja 650 prioritizes touring comfort and accessibility.

To judge the Kawasaki Ninja 650 purely on its paper form would be a serious mistake. The two-day test showed once again that performance data carries more weight at the pub table than in the wild. Kawa's sports tourer does exactly what it is supposed to and, thanks to the constant revision and the new features added for 2023, is still an enrichment for the class. Only hobby racers should be warned, as the name Ninja still stirs up a certain expectation that the 650 does not fully meet.
