how much does street bike insurance compare to a sport cars?

Right now I have an 06 wrx sti, insurance is crazy with me being 19 and not having the greatest record. i've been wanting to get a bike(starting with a ninja 250 probably, no experience aside from some dirt bikes when I was younger) for when spring rolls around, but if it's as high as my sti there's no chance
