I am a new rider for sport bikes. Ive ridden dirt bikes off and on for several years. Im looking for a good bike to start out with. My brother in law is recomending basically any sprtbike 600cc and under that is not R or RR rated. He says i should look for the ninja ex500, SV650, and F3's. I like the Yamaha YZF 600 but I cant seem to find one for a good price. Do these all sound like good first time sportbikes? Also Ive found a few good deals on F4's as well. Is there a big difference amoung the different F4's like the F4I and what not? With whatever bike I choose money is a factor. Im 19, a college student and poor lol. I know size also matters (rider size that is) Im a small rider. 5'9" 125lbs (57 Kilos for you metric mates) My biggest throwback with the 500cc bikes is the top speed, which I have seen posted at around 100mph. This seems slow to me since my 1.4L Protoge can top that. But then again its on a bike not a car. I know there are MANY posts asking about first time bikes so I appreciate you takin time to reply to this one.
