there arent very many but maybe a couple that can use what a 600 has. why spend the 12g or 13g whatever they cost, when u arent ever gonna use all the power??? if u drag i understand but for anything else i dont see the point in it. @ 23 ur insurance will be stupid on a 1000 and this is ur 2nd bike, and just got the 600 earlier this year if memory serves me correctly. u really think ur ready for a 1000??? just be honest with urself man. not trying to flame just IMO. thats the truth, i know of some guys that can run circles around a 1000 on a 600. but i know guys on a 1000 that can run circles around 600's, but also know pently of guys that cant ride either for shit! haha
