Thank you uralbob for your opinion regarding the handling.
I have only seen near me next generation mks that would accelerate slower than mine on straight roads for several kilometres so I concluded that the 1st generation is a bit stronger in terms of engine power but I may be wrong . A lot of parameters like gasoline quality, engines condition , transmission/chain sprocket efficiency, riders determination , aerodynamics and so on could lead to faulty judgements . The difference may be unnoticeable..
For sure though black is the fastest among all generations 😀
