Hello, im in the market for one of the 2, however the 08 model is $1000 cheaper, wondering if the 09 has enough improvements to vouch for spending an extra grand?

I don´t think so and once the 2010 bike with EFI is out, they will both drop their market value by a good amount.

I have an 08 and have ridden an 09 and I honestly couldnt tell much of a difference in handling between the two at all, but I am far from a fast racer. I say save the money and get the 08 and then spend the money you saved on an exhaust and some suspension work!

Agreed, spend the money saved on a good suspension setup, and an exhaust.

I know the axle size for 09' is larger than previous years. I wouldnt get EFI unill its been out for a couple years also. my buddy bought the suzuki first year with EFI and is having all kinds of problems with it. I have no problems with the carb.

Rear hub and axle, and the swingarm are about the only noticeable changes, neither of which are noticeable on the track to anyone who's last name isn't Stewart. Akira Narita is running an 08 swingarm on his works bike in Japan.

Per MXA -

1. Ignition stator plate - 3 bolts on '08 - 4 bolts on '09
2. 1st and 3rd shift fork shafts increased by 4mm - easier shifting
3. Top triple clamp - more handlebar mount position options
4. Bigger rear axle - 22mm on '08 - 25mm on '09
5. Redesigned swingarm - weight savings & redesigned rigidity balance
6. Lighter by 350 grams = 12.3 ounces - not a lot but it adds up in the right places
7. Repositioned swingarm linkage mount points

Is the above list worth a grand, only you can answer that.

yeah, but the first years always sucks. wait for the 2011! remember the last year of a generation is best for that year. 2009 dialed in with jetting, will be as good if not better

The only good thing I have seen from EFI is that if you crash in the opening race of the reason you will be able to start your bike back up faster then the guy that doesnt have EFI. Even though about 5 out of the top 10 fastest riders dont have EFI ... Its to new to really be a but step , just like when Henry first started racing with the four stoke.

Some people will get this...some wont. Save your money for track time and things that will help you be a faster more confident rider. I.E springs, revalve ect..
I'm trading my 09kx250f for a 08 yz450 , did a lot of reading, dont think the 09 is all that much better.

That can be true, but the '98 YZ400 did not suck, nor did the 2000 YZ426 (even though it was improved on later), nor the '03 YZ450, and definitely not the '06. I'd say Yamaha has a fairly good record with first year issues.

Especially when you add to that list the '01 YZ250F and '99 YZ250. Both of those engines have barely been changed since then, and are still great engines. Also the '05 YZ125 was quite a success. I'd say Yamaha has the first year thing down pretty good.

Yeah, Honda has dumped a few poopers on the public in the first "few" model years. For instance the 1997 Honda with the new aluminum frame was despised in the mags. And the early Honda crf four strokes have been known to need frequent valve jobs, I don't know if they have fixed the problem with there valves yet! Also the 09 Honda has a host of its own problems, aka bad clutch and decompresson breakeage proplems, suspension check the mags.

Yamaha made the switch to aluminum frames without a hitch, the mags loved them. Seamless. The early Yamahas havent been know to have the best suspension, 426, however this has since been fixed. As they now have the best.

Unless your a extremely detailed rider and/or have had experience testing, your most likely not gonna notice the changes IMO.
