There was a reason wh the f2 was such a good seller.
It's still a very functional bike. Does it stack up to an f4i. Depends on who you are doing the stacking.
Personally I'd save my dollars and ride the f2 for as long as I could the cost difference is going to buy you a lot of gas and maybe even some up rated suspension goodies or a track day or six.
