First off, I have been riding a scooter for the last 5 years. I started on a 50cc. got my license, then moved up to a 170cc scooter. I now would like to get a motorcycle, and have narrowed it down to a Ninja. My question, I am 6'1 and weigh 260 lbs. I dont do much freeway driving, but feel that I have no extra power on the when on the freeway. I hit about 75 and thats it. I like the price of the Ninja 250 at about $4000. I found a 650 for $6850. Thats a world of difference in price. I dont want to go overboard with price, and dont want to upgrade for at least 4 years. Will the Ninja 250 be enough bike for me to commute back and forth to work with occassional freeway trips for someone my size? Or would I be best with the fuel injected 650? Also what is the cost in comparison to maintain these 2 bikes? Thanks in advance.
