I am probably going to be giving up on the Ninja 500 I have and selling it soon. One reason is because the bike turns out to be a bit too big and heavy for my wife. She is petite and prefers something lighter and a tad shorter. She does like the 250 so I'm willing to trade up for that. My question is if I get a 250 and ride that for this year till I get comfortable on it on the streets, will I be able to handle a 600 later, even though I'd be skipping the "500" level? And how would the 250 be on short highway trips?
