Anybody parting out an 07 already? If so dibs on the radiators, in particular the left one. Mine isn't quite looking like a radiator should these days, still holds water, but it's a ticking time bomb.
The new 07/08/09 radiators are definately "soft" and are easily crushed but they are very "watertight" after loosing their orginal shape. We've seen some pretty badly crushed and miss shaped 07/08/09 raditors hold water after they looked like they should have failed.
The new 07/08/09 radiators are made by a German company (the older GG radiators were made by the same company that supplies radiators to KTM) and are claimed to be more efficient because they are slightly longer and have more cores which equals more surface area.
If you get a replacement 07/08/09 radiator consider having it reinforced by a local welding shop were they can add some 1/8" thick aluminum to the outside surface, ff course if your having one reinforced have the other done as well. Or invest in some radiator guards.
The cost of the custom fabrication "stiffining" can run around $80.
Raditor guards run around $100 and both Force and Scorpion make good ones. I believe Moose Racing makes guards as well but we've never used them so its hard to recommend them. Others here on GGR.org should be able to comment on the fitment of the Moose raditor guards as they may be another good alternative.
Also don't overlook trying to find an older GG radiator as it will work as well and may be cheaper and much easier to find.

If anyone is in the southeast, ICW does a very nice job beefing up bike radiators. I've used him for a number of custom radiator projects, and he does great work.
These were Fluidynes from a KTM 525 EXC four stroker, and now live on my '04 300 EC. They hold several ounces more coolant, and boil overs don't happen anymore in the summer heat.
