yeah hate to be rude but its starting to feel like this is the only thing talked about here. look around and youll see tons of threads about it.
all i really can say that hasnt been said is: fear the gixxer. it should command awe, respect, and MOST importantly, fear. one small mistake and your front wheel is 4 feet off the ground or your headed into a tight turn way too fast. a gixxer will make you feel like you can do stunts and rip through traffic, and in the right hands those bikes can do just that.
the honest truth is that most people on here that are so passionate about steering noob riders away from those bikes because they know someone who has died or they/a friend has been seriously injured on one. there's nothing like a skin graft to remind you for the rest of your life what you did wrong.
also, buy gear first and the bike with whats left. gear is the most important thing EVER for any motorcyclist.
get the gs500f if you want good looks. try a used bandit 600 for a more powerful bike that is still managable to learn on. if you absolutley have to get something faster than the bandit, try an sv650s. it looks good, handles awesome, and is fast. thing is its STILL not as deadly as a gixxer, r6, or cbr. good luck and be safe.
