Judy,
In 2008 the EXC line underwent a complete overhaul. New frame, brand new totally different engine. The 2009 's got minor updates from the 2008's.
The 2007's have the very reliable RFS engines that have been proven excellent for dualsport use.
The 2008-2009 engine has mostly been reliable, makes better power than the RFS. The 2008-2009 chassis is supposed to be a big improvement.
I've ridden both and the 2008 was a better feeling bike to me.
Hope that helps.

2007 was the last of the RFS (racing four stroke) engines. 08 - 09 have a new engine design that includes separate oil for engine and tranny. RFS engines have a single shared oil.
also the valve arrangement is different. 08-09 use bucket under shim like a drz. i dont know the terminology but the RFS has a screw with locking nut.-so the valve adjustment is different.
many people consider the 07 a highlight year for this bike.
you get most of the bugs worked out like the 05 gear problem ( fix with 06 ) and also first year of factory plated.
not sure about the 08-09 but the RFS 2000-2007 is highly recommended to run an electric fan - oil cooler - and cush drive if plating ( save tranny )
i think most online community would agree and many consider those 3 essential.
ktmtalk.com may help
doesn't mean anything but i would pick the '07
i ride an '04 with a street lighting kit.
best of luck al

I waited to install my fan until I had upgraded my stator because I had read some guys on ktmtalk had run down their battery. This was only if you ride slow tight stuff all day long where the fan will be going most of the time. Now with the upgraded stator I can run the fan and a better headlight all the time and it won't run down the battery. I usually turn off the headlight in the trails anyways, force of habit from before the upgrade. I still have the daytime running light on but I think that's only 5W.

What did it cost you to upgrade the stator? I recommended that to Claw, but he didn't want the hit right now.
I can say however that even with the daytime on, it will still kill the battery if it's tight and slow enough. (Salt Spring Island riding = 20km in 4.5hrs to 6hrs)

Can't remember well, but I got the stator and regulator kit for (I think) $150. It puts out 100W at idle and does the job for me. Even on days where I'm in 1st and second all day long (18km for the whole day) I was still able to have the light on and use the starter just fine.
If you haven't modified your wiring much to make your bike street legal, it's very easy to add the stator, regulator and fan... even I was able to do it! The only hard part for me was that Vancouver Supermoto installed the wiring kit to make my '06 525 EXC street legal and I wasn't sure where to plug in for the stator connections because their wiring kit had different connector ends. On stock wiring, the instructions that come with the kit are perfect.
