Good advice already given by all...SV650 is a great first bike, as long as you approach it sensibly. Easy to ride, reliable, good handling, etc. Get some training. Not only basic, but advanced if you're going to be riding hard. Don't try to learn it all on your own. Take advantage of the learning all of us have done and are still doing! Don't jump to the 848 too soon. Give yourself time to really hone some skills. Finally, ATGATT (All The Gear, All The Time)! Show your riding buddies you know what's its all about!
