First of all a Banshee is a 2 stroke 6 speed very light twin cylinder 350 quad with instant on power at the flip of a switch. You cant go wrong with the banshee, and you arent ever gonna outgrow it, It might be alittle fast for your first true quad but it definatly in my opinion will roast the 300ex, or it should anyway, Mine is a six speed twin 350 and it rocks out, this is my third shee and i wouldnt have bought anything else, And i could have and can afford 2 of anything on the market brand new and i choose to buy a used banshee and mod it out, My uncle has a kawa 700 and a honda "dorkman" 700 and i smoke his ass all the time, I am 5'4" and weigh 135 so it kicks ass with me on it. Trust us on this you wont go wrong with the shee.
