don't compare to the ktm of your friend...
you can't set stock suspension anywhere near that,without changing anything.
it's made to ride comfy on the road or gravel roads.
any bumps, make it inadequate... either learn to live with it and adjust your speed offroad :-) or spend some money to get it somewhat better.
it all depends what you're expecting from it and what your skil level is.
bear in mind, if you want to go ride with your mates with the ktm's, better get a second bike.... choices choices
