I did want acceleration, and the NA xfire didnt have it.... I bought a bike. Now Im satisfied on all around ultimate performance... My xfire will still be modded, it comes with the testosterone. Am I going to put shiny neon and rainbows all over it...... Hellll no. But I am going to make it even more unique by my own standards, by my own hands, my own way. Show me a car enthusiast that hasnt done something to their car to make it unique.................................... you cant... and the NA isnt slow but its by no means fast.
