They get set up much like a Prowler.
They are very quick...ran one all this year.
From what I've been told they were made from Prowler parts and left over 2-stroke chassis parts.
It is fully adjustable.
From driving a Prowler and a Ninja the Ninja is a bit softer frame flexes a tad more than a Prowler.
You can really throw these in a corner and hang on, and they shoot out of the corner much like a Prowler.
High cross kart, usually around 65-67 cross... Really like it... Set it up just like a Prowler.
Don't know about a entry level kart....kept right up with the best of the best, Slack, phenom, Prowler, ultramax etc...
I will say I like my prowler better, but have nothing against the Ninja
