Welcome to the forum, and congrats on the bike. I'll 2nd what everyone else has said and say be careful, and MAKE SURE TO GET GEAR!!!! Being 17 your still learning the road and most likely you will have a fall or 2, I'm not wishing anything bad on its just facts, and when you do go down it will be a lot better if your ATGATT all the gear all the time. That being said don't let it discourage you, enjoy the incredible machine, respect it, and don't get ****y. It's one thing to know what's under the hood but another thing to drive like your trying to prove it.
I'm saying all this because I know how I was at 17, I had already had 4 different cars and trucks, blew 3 engines, and had already got over 10 tickets and had paid out about $10,000 in fines and lawyer fees. If I would have got a bike at 17 I don't think I would have lived to see 18. I don't think I learned my lesson until about 3yrs ago, and I see what everybody was trying to tell me now. So have fun but be safe!
