zilla is like a riding on the roof of a vw bug, i really dont care for the zillas, they are too big, seemes like you need more area to turn. you can really tell how wide they are when you ride one, and look out for tight spots, they dont fit. now if you are a plus size guy then the zilla is the bike for you. or maybe its just too much bike for me. haha
now the 250 with a 500 motor, shoot look out. i love the bird, fast and nimble. whip it around anywhere. but dont ask me why i have 3 zillas tho. guess i just liked the fact that i can say i own one of them, i mean 3 of them. lol
if i was to start over and know what i know now, there would be 3 bikes in my garage instead of 6. 1 250, 1 zilla, and a bird. i like to ride the 250 for a few min, then jump on the bird, and it is just crazy on the power difference. i think it really does stretch your arms. they pull very hard, want to climb a big hill, just hammer it at bottom and coast up the rest of the way. and if you have a zilla that feels lazy and does not freaking rip, then it needs work. better call jerry hall
there is nothing like a good running 500.
but this is just my feelings on this, take it as you want.
come over and take mine for a ride, it will make you jealous.
