dude you want the f4i because it is fuel injected and the yamaha isnt........both around 100 horse power but the styling of the honda far exceeds the yammy.....plus the air intakes on the f4 are awesome and the honda has a better resale value....i was looking at the yam for my first bike but after review chose the honda....built like a tank ,,,,dude they just dont bresk....goodluck
