This is for those who have both or ridden both older 2 stroke viper and newer 4 stroke Apex. I have a 02 viper and recently puchased a 07 apex how do these two sleds compare. I have not driven the apex yet...what should my expectations be. Im thinking they should be pretty close in performace. Whats your thoughts on: top speed, off the line, handling, fuel milage Ect....
