I've been riding a 2005 Crf450x for about 2 years now and while i love the bike, I just don't know if it's the best for me. I previously rode a CRF150R expert and prior to that a CR85 big wheel also. The 450x was sort of a hand-me-down from my dad or I probably would've gone with the R model. I only ride in the desert but I wouldn't mind trying out a couple of my local tracks. Even in the desert sometimes i feel that the 450x is just a little too heavy for my liking and wish I had something I could throw around a little easier. I've been eyeing the 09+ 450s ever since they came out and was wondering what your guys' opinion on the EFI is. After some looking around on here I've noticed a lot of people really like the 07 & 08 models. Anyway, I'm just trying to figure out whether upgrading to an 09+ would be worth it or not or if I should look into an 07 or 08 and stay away from the EFI. And if that's the case, would it really be worth upgrading in the first place?
