Welcome to SBW!!
Talk to other riders,go to the motorcycle dealers,read all the M/C mags you can,check out a bike show,in other words:get all the input you can!!
You choice should be made on several criteria:
2.How much you are gonna spend,(include extra$$ for things like :insurance,leathers,helmet.etc.etc.)
3.What kind of riding your are going to do: more canyon carving or that and also some long distance riding too.
What ever you decide,use your head and ride at your own pace,don't let others force you to ride in situations over your head!!
This is the BEST sport out there if done safely AND done smart.
