I bought the G2 that was private labeled by KTM hardparts, I guess it is the same. I installed the 400 cam on my 07, and all I can say is sweet! My bike was not terrible as some have posted, however the G2 added alot of control and finesse that I think will translate to better drivetrain wear and more traction on slippery conditions.
I paid like 95 bucks, but I can say it is a very well built piece. Nice install when you go to do heated grips, but be sure to install a plug on your wiring so that you can remove the heated element if you want to change cams. I like the 400.
