Is 50 horsepower enough to turn the rear wheel?

Hey guys! I bought me on 01.03. ne`Kawasaki ER5. Last Tuesday I registered them and drove with them every day until 2 days. I am 29, driving license since 2003, but have no Möp experience…. 2005 times a week ne 34 Ps Er5 borrowed, that’s it.. On Monday’s go to the driving school again, the driving teacher can look at it all from behind, and after that’s on a practice site. Quasi a driving safety training for poor ^^ So much to me. Now on the subject. ollgas sometimes comes before my mop turns so up to 7000 and then slowly descends again, up to 5500/6000…..almost as if you were driving on (just at more speed). I have already thought about a grinding clutch? Or a spinning rear wheel? It was always quite cool up to now. The whole thing always happens in absolutely upright position.(When else should I give full throttle?^^) But except for the speed change I don’t notice anything. As I said, I’m driving now. It’s only been two weeks, but I would have thought you’d already notice a crazy wheel on your ass… So what do you say?Is that possible with the performance or not? Mfg Rene
