first off, insurance on a japanese litre bike is insane. Try about 3k a year for full coverage....yes 3 thousand. I say go get that thousand cc bike, just take out a BIG life insurace policy and put me as beneficiary.. all seriousness,you WILL wreck. Everyone does but you will prolly do it sooner and harder on a thou. A 600 is the way to go. 90% of people cant ride a 600 to its full potential anyway. I actually have better laptimes on my 600 than on my 1000. bottom line, 600 is all the bike you need
